Politics And Science At The LHC

In the days before Madison Avenue, public relations and spin doctors, Science was free to speak for itself. Like any other activity it was criticized and judged on its activites and results by media and the people. If the public had questions, the scientists answered them. Political games were for government and business. Now big science instituitions and labs with their own bewildering bureaucracies, have developed an interface to present an ideal world of science through their press offices and lobbyists. They sell science like GM sells cars. Somehow the media seems not to have noticed the difference, taking spin doctors' science press kits and sound bite analysis at face value.

Camera shy bumbling scientists with thick accents who were honest about what they were doing, if you could follow the science and what they said, have now been pushed behind closed doors while the media gurus have taken over. At CERN they go a step further and stage media science events, like the big ballyhoo September 10th to show off the Large Hadron Collider during a preliminary start-up test. A modest start-up showcase for an extremely powerful atom-smasher that smashes nothing that day is played out as a big success and a victory for LHC safety. No more doomsday. Doomsayers all wrong, CERN always right. Then three big things go wrong which are skillfully downplayed. While the little ball of protons zips around, the CMS computer system is being hacked by the Greek Team and that for 2 days at the home of the World Wide Web? A 30 tonne surface transformer blows 36 hours later during a thunderstorm. Then a massive failure occurs in the cryogenic cooling system which cripples an eighth of the 17 mile collider ring. Very little information released, but a lot of reassurances on "teething troubles" at the giant baby collider.

It can get worse. The latest surprise from CERN is a new paper published which finally comes to grips with part of the problem with the helium used in their massive near absolute zero cooling system. The CERN paper dismisses every safety concern with helium without considering all of them in "There is no explosion risk associated with superfluid Helium in the LHC cooling system", September 23, 2008, by Malcolm Fairbairn and Bob McElrath of the CERN theory group.

Its focus is helium-4 bosenovas at the LHC and cold fusion during these events.

The short answer is, "We conclude that that there is no physics whatsoever which suggests that Helium could undergo any kind of unforseen catastrophic explosion."

Sounds like these guys were in a hurry, but right behind the Eight Ball. "that that" is fast fast, potential there for a new type of doublespeak. Of course there was an explosive release of one to two tonnes of superfluid helium last time, but that was different. Not a real explosion, more like your radiator exploding, not your gas tank. But the paranormal mindbender winner is, as KFC at the physics arXiv blog said of CERN's conclusions, "That's comforting and impressive. Ruling out forseen catastrophies is certainly useful but the ability to rule out unforeseen ones is truly amazing."

It's a welcome response from CERN even if it is only partial. I first raised the issue myself in ScienticBlogging, July 2nd, 2008, in "Superfluids, BECs And Bosenovas: The Ultimate Experiment" reprinted here on The Science of Conundrums. When CERN didn't bother answering, I contacted their LSAG people via email twice, August 25th and 29th, but included other helium risks like the production of helium-3 via LHC energies ionizing helium-4, where helium-3 bosenovas obviously should also be considered. I received no reply and CERN's paper doesn't address helium-3 bosenovas either. I also wrote about nuclear events in helium, certainly a potential danger in helium-3 and even possible plasma and fusion reactions of helium-3 at the LHC. Again no answer from CERN. Only this sweeping rebuttal: "There is no physics whatsoever which suggests that Helium could undergo any kind of unforseen catastrophic explosion" Is this science or speculation and politics? Don't worry from CERN, but this time not from the CERN PR department, but their CERN theory group.

If this sounds a spectacular failure in addressing safety issues honestly, well what other explanation is there? All they had to say was Helium-4 Bosenovas are Bunk, and Cold Fusion of Helium-4 Stinks. Of course we hope other physicists will examine CERN's 6 page paper and let everyone know if CERN's arguments are sound. Even if they are on Helium-4, one mosquito does not a summer make. Though there have been plenty of light speed protons in another CERN public relations context, masquerading as mosquitos.

If the politics of safety can override safety concerns, like chicks sprawled on red sports cars, are there other similar sales jobs on safety approximating the scientific? Where is the CERN Model hiding out? Look no further than the pharmacuetical industry. When people die, safe products are recalled. Tons of safety reports and tankers on a magazine sunset, and then a giant oil tanker spills and kills birds and animals and fish by the thousands. With 6 months of downtime at the LHC thanks to accidents can happen, they've got plenty of time for gearing up for a new sales campaign, CERN TV commmercials. We're still waiting breathlessly for "Spin the Collider and Win" or "My Best Friend is a Collider / When he gets warm I get hot / Gimme gimme gimme more / My collider / Bang, bang, bang / Big Bang. Be there! Beat Doomsday! Make it happen. Geneva is to die for. Hunker in our bunker or dance the night away. Win a trip for two at participating Dunkin Donuts, your Collider Central. Free Collider Keychain in every limited time only Giant Collider Donut. Careful when you munch. Be safe, dunk first."

Nowadays politics is part of big science. Recently a Climate scientist at MIT, Richard S Lindzen wrote a paper, "Climate Science: Is it currently designed to answer questions?" Although the author states that the focus of his paper is on climate science, "some of the problems pertain to science more generally."

Lindzen notes "the change in the scientific paradigm from a dialectic opposition between theory and observation to an emphasis on simulation and observational programs." The LHC Machine is certainly part of this change from earlier Einsteinian physics to let's see what happens when we simulate the Big Bang.

". . . an emphasis on large programs that never end." Fifty years of CERN and now on a budget of $1 billion a year with a $10 billion broken collider that might never work right.

". . . the hierarchical nature of formal scientific organizations whereby a small executive council can speak on behalf of thousands of scientists as well as govern the distribution of 'carrots and sticks' where by reputations are made and broken." CERN in a nutshell.

". . . the politically desired position becomes a goal rather than a consequence of scientific research." New Physics sought.

". . . scientists adjust both data and even theory to accommodate politically correct positions, and how opposition to these positions is disposed of." Safety or the appearance of safety? Critics are doomsayers who just don't understand.

Well this still works for CERN because it is an enormous organization that has a small powerful directorate and a Director General with Presidential Powers, 'carrots and sticks'. So big and influential in physics that those within and those outside are wary of demurring on anything. Even 20 EU governments that support CERN financially applaud rather than criticize, but then they're not scientists, or cost accountants, and just as misinformed as anyone else. If there are any diplomatic groans, it's probably because the big collider party this October 21st has been called off. In the interests of vitual safety, no doubt here a Virual Inauguration would be safer for Heads of State. Cheaper too, a few souvinir hardhats FedEx'd. Click for Bollinger and caviar now.

No doubt CERN will spring for the real thing. These guys pay their bills. It's prestige that still counts. With participation in other nuclear labs in Europe and friendly relations with many others worldwide, CERN amounts to something like the Church of the Middle Ages. Not based in Geneva for nothing. In 1955 the Swiss Government gave CERN carte blanche to operate in Switzerland as part of the deal to locate its operations in Switzerland. The list of concessions and priviledges CERN enjoys gives it the power of a city state (currently 2,600 staff, plus some 7,931 scientists and engineers, in Wikipedia) or in modern terms, that accorded to a foreign government's embassy and its diplomats. When CERN expanded into France in 1973, the French government was more circumspect but awarded CERN similar if more limited powers. Neither country though has jurisdiction over CERN, its property, its personnel or its activities. Though the French have reserved some rights including the right to intervene if there is a threat to France. If CERN blows up Geneva, Switzerland will have to sue Fermilab. An obvious mistake to put an organization above the law, like we didn't know the gun was loaded. Anyone in Switzerland or CERN care to bet that the obvious mistakes are the most statistically significant?

Surely if there were doubts within CERN as to problems or even the advisability of the Large Hadron Collider in the first place, we would hear about it? Not much has slipped through the cracks in the CERN PR department except their tactics. One source is CERN archives. Some CERN people have found themselves embassassed in hindsight when their candid comments were recorded in CERN videos, transcripts and documents.

One insider has recently commented, not realizing there was some unwritten code of silence. A CERN physicist, Tommaso Dorigo who works at the LHC CMS experiment, wrote in his blog, A Quantum Diaries Survivor, "In fact CERN appears a bit up-tight about the latest events in sector 34 of the LHC tunnel. He goes on to say ". . . since my blog is targeted as a possible source of leaks. . . And if I play fair, maybe I am allowed to survive here, and maybe one day I will stop being threatened every other day, in the name of protecting internal information of the experiments I am a part of."

Dorigo concludes, "Of course, I still assert my complete disagreement at a way to conduct scientific experiments paid with your tax money which resembles the management of the Pentagon rather than an agorà of education, research and scientific communication."

LHC Quench Stops CERN: Re-start Delayed Again

After last Friday's massive quench at the LHC, CERN has announced that re-starting the collider will have to wait even beyond 2 months for repairs and downtime. With a planned winter shutdown in late November, even if the collider were ready, there would not be enough time to continue tests. Re-start of the LHC should be in April 2009.

Day 7 into the major accident damaging part of the LHC helium cooling and superconducting magnet systems, indicates little progress as yet. Scientists at CERN are still investigating the failure in Sector 3-4, an eighth of the 17 mile ring of magnets that are normally cooled to near absolute zero temperature. The extent of the damage is greater than was reported by CERN initially. Dismissive at first of the collider's "teething problems", CERN suggested that the LHC could be operational soon. A sketchy press release was followed by another sketchy press release.

Oddly after the BBC discovered the massive quench of about 100 magnets in a log entry on a CERN website, "the entry has since been removed" according to TimesOnline the day after.

It was also TimesOnline that said on September 21st that a connection between 2 giant magnets melted, with a release of one tonne of helium, adding the heat also melted 2 giant magnets, causing an explosive release of liquid helium which blasted helium gas through the ring tunnel. No one was hurt as no personnel were in the collider ring said CERN, normally only off limits when proton beams are operating. CERN said that at the time of the accident last Friday morning, there were no beams and only admitted to "a large helium leak" and "a faulty electrical connection between two magnets, which probably melted".

The only piece of real news by CERN's chief spokesman, Dr James Gillies, who does the standard tour of the major media outlets to reassure journalists, outside of his department's press releases, was about the damaged magnets in question that he identified as giant quadrupoles, in the Telegram UK, September 20th. Later the probably melted connection turned out to be a busbar, a type of reinforced splice of magnet ribbon cable, one of many such connections between magnets.

It wasn't exactly a routine failure. Commissioning was still going on in Point 4 and on either side into the later damaged zone of Sector 3-4. and in 4-5. The high energy test was of the RF system for anticipated higher loads when it would be used to power up beams to 5 TeV, that were scheduled for later this year.

As of today only specialized safety teams and technicians have been allowed in to check for hazards and equipment damage. Following the accident Sector 3-4 showed some continuing warming of magnets and helium, some of the warmest then cooling, but now the Sector has been partially re-cooled. Most magnets are at 30 K, with no further helium leaks reported.

Eventually the damaged Sector 3-4 will be warmed to room temperature for repairs to be effected, but that would mean that remaining helium would have to be drained from the system first, and that hasn't started yet. Since temperatures have been brought down, it seems that the strategy is to cool the helium enough so that it can be safely drained as a liquid and stored as it's very expensive to replace. At least two damaged quadruoles will have to be cut out as they are welded together and then new ones welded in, a difficult and expensive proposition.

Coming on the heels of two other major failures, the hacking of part of the CMS computer system, during the big September 10th media launch, and the destruction of a 30 tonne surface transformer during a thunderstorm shortly afterwards, powering 2 sectors of the LHC cooling system, the need for a more careful re-launch of the collider is apparent to CERN, hence the further delay to spring.

CERN publicly has put on a brave if vague face, with its first very short press release of the 20th September, "Incident in LHC sector 3-4", though it was abundantly clear the day of the accident September 19th that it was more than an incident, as reported by the BBC that day. Even on the day of the accident, according to Scientific American, "CERN said on Friday that "The LHC is on course for [its] first collisions in a matter of weeks", just a day later it announced the minimum two-month repair job." Lately Dr Robert Aymar, Director General of CERN referred to the accident as "undoubtedly a psychological blow."

But there are other factors leading up to the accident that haven't been addressed. Certainly timing the First Beam to suit a media bash opening, when the CMS was being hacked, and still going ahead with it, suggests the need to perform for the media above ordinary safety considerations. Several other factors also indicate a rush to perform for the media and a huge worldwide audience.

Reuters reported September 10th, that there were "Small electrical issues before CERN machine start-up". "Project leader Lyn Evans gave no details . . ."

Operating the collider during a thunderstorm is certainly a known risk at the Tevatron, and 36 hours after the September 10th opening, a 30 tonne surface transformer that powers part of the helium cooling system failed during a lightening strike. Cause of failure still not confirmed by CERN.

According to the LHC Commissioning with Beam page, "The winter shut-down will then be used to commissioning and train the magnets up to full current, such that the 2009 run will start at the full 14 TeV design energy." Lyn Evans reiterated the same point in a talk on "The LHC Machine" at a CERN colloquium, Strings 2008, August 18th. Some installed magnets from another supplier had to be retrained. Earlier this year there were plans to jump to 7 TeV. Then 5 TeV was announced as rather a surprise, the new goal per beam. Where the damaged magnets from this lot of not fully trained magnets?

What if CERN has run out of luck? They have been lucky, not running beams they say during the transformer failure and the huge magnet quench, but what if they had been running beams? Beams could have been lost causing more damage. They ran beams during the hacking of CMS, but luckily there were no collisions.

There's a long road ahead. As Fermilab/SLAC's sponsored magazine, Symmetry wrapped up the transformer accident at the LHC, "These kinds of hiccoughs in starting up a large collider are not surprising as the LHC has millions of critical components."

What? Only millions?

Accident Cripples LHC

No collisions, no beams either next week at the LHC. The BBC reports an alarming quench of about 100 superconducting magnets today, that heated up as much as 100 C. A tonne of liquid helium spilled into the tunnel and the CERN fire brigade went in. Cause of the quenching has not been announced, nor have any injuries been reported. Liquid helium leaks vaporize back to a gas almost instantly and would freeze or choke personnel present.

Ordinarily magnet quenches occur when proton beams are lost or scatter into magnets, causing helium coolant and magnets to heat and lose their superconductivity and their power to keep proton beams within the collider. CERN doesn't say whether beams were running today during the accident. They would have been at their lowest power 0.45 TeV per beam, though beams 11 times more powerful at 5 TeV were scheduled before October 12th. Vacuum conditions were also lost said the BBC, which suggests beam damage, though CERN hasn't commented.

This is on top of another major failure to the helium cooling system. Last Friday the 12th's thunderstorm burned out a giant 30 tonne 12 Million Volt Amperes surface transformer that powers some of the helium cryogenics system. Although CERN admitted the problem yesterday, without mentioning the thunderstorm, and said the transformer was replaced last weekend, there was no explanation for the long delay in informing the public. The failure of the transformer caused an initial warming in the helium coolant in 2 of the colliders 8 sectors, some as late as September 17th at near 7 K

Whether an ongoing transformer problem contributed to quenching has not been announced. The TimesOnline initial report on damage said, "One of the beams had been captured by Friday, but work was then interrupted by the loss of electrical transformers that power the cryogenic cooling system . . ." A beam apparently running during the thunderstorm, and more than one transformer lost. CERNS's lastest progress report yesterday was sketchy.

The damaged Sector3-4, an eighth of the 17 mile collider has still not been stabilized since this morning's accident. About half of it or a mile length was well above normal 1.9 K design temperature, about a quarter of the sector and its magnets this afternoon at 15:46 PM were about 82 K to 110 K. Currently all magnets have warmed. The warmest show a slight recovery from 110 K down to 99 K. and Sector 3-4 is still in crisis as of the 20th September 0:418 AM, with no accurate readout for about half the magnets, and the rest showing more warming, with a few outside the spike zone climbing abruptly in temperature since this afternoon.

Given the gravity of the accident, repairs would take a week or longer.

LHC Fails Thunderstorm Test

Nature had her own ideas about testing LHC safety. A thunderstorm last Friday knocked out some transformers at the LHC near Geneva that are part of the helium cooling system, that cools the magnets that keep the proton beams travelling (near light speed) on a circular path through the collider. Technicians have been scrambling to fix the problems, but not before some magnets warmed well above standard operating temperatures, some reaching almost 7K from the usual ultra cold 1.9K .

Electromagnets at the LHC need to be this cold to be superconducting, or at peak efficiency, in order to deliver extremely high magnetic fields in the 27 km ring of 1200 giant magnets and thousands of smaller ones, at 8.33 Teslas or about 200,000 times the earth's magnetic field strength.

Everything about this atom smasher is boggling, including the numbers, like its cost at about $10 billion and CERN's yearly operating budget of $1 billion, with over 2500 physicists working on site.

Reports from CERN today state that repairs were successful and the collider will be poised for proton collisions next week at a base energy of 0.90 Trillion Electron Volts. CERN is aiming for much higher energies never before attempted, 5 TeV per beam before October 12th.

CERN didn't say whether the collider was operating with beams or not during the emergency. If it had beams shooting through the ring, protons could have scattered, further warming and quenching some warm magnets, that might have exploded if the automatic heaters had also been affected by the power failures. Several sectors did warm partially at the LHC. If they all had, in the worst case scenario, beams might have unravelled and crashed down the LHC, causing a catastrophic failure. With the warming of magnets and helium coolant, up to 40 refrigeration plants above and below ground could have failed, usually with a loss of helium. In December 2003, the Tevatron had a catastrophic beam loss and a major quench, not related to thunderstorms.

Some hassles during storms have hampered operations at Fermilab's Tevatron, currently the most powerful collider until the LHC goes full blast. Even though both colliders are largely underground, lightning travels well though moist earth or wet clay, and part of the LHC in the vicinity of the second largest experiment, the CMS, has been excavated from clay, so unstable that it had to be artificially frozen during excavation of the giant CMS cavern. Hence its nickname at CERN, see-a-mess.

Like any machine the LHC is vulnerable to its environment and its own weaknesses, not forgetting the colossal energies and particle collisions it will produce.

LHC Not So Safe

The Greek Security Team, computer hackers who know Greek at least, left this souvenir behind on the CMS experiment's computer system. The attacks went on for two days, September 9 and 10, part way into First Beam commissioning. "We are 2600 --dont mess with us" was their sign-off.

One of the CMS team fighting off the hackers said it was a "scary experience". Dr James Gillies, chief spokesperson for CERN said "It was quickly detected." A half dozen files were uploaded by the hackers. One CMS computer file was damaged. It could have been worse. An CERN insider commented that if the attackers had penetrated into a second computer system, some of the CMS could have been turned off, adding, "it is hard enough to make these things work if no one is messing with it." The CMS is a gigantic solenoid magnet that could slow down traffic in Paris, though here it will be used to detect muons with its millions of pixels and sensors, or whatever else registers during proton beam collisions of extraordinary power.

CERN of late is under siege as the LHC moves closer to full 5 TeV beams before October 21st. Emails and telephone calls are flooding in from panicked people fearing the worst, from black holes to tsunamis caused by collider operations. If tsunamis are typical of the irrational sort of fears, CERN has admitted micro black holes are a possibility, but won't be dangerous.

The current blitz against CERN is mostly by professional spammers. Yesterday CERN got 1.4 million emails, about 98% spam.

As usual CERN is not worried. "There seems to be no harm done." said Gillies.

The Black Hand Of Dr Cern

Not a 50's B movie, but the latest Press Release from the biggest black hole on the planet, sucking up an astronomical $10 billion and ready for more, (gulp) dollars. What an appetite! Even now it's going after spare change. $10 million a month from the U.S. alone. When will it end? Is any sofa safe from the Black Hand of Dr Cern?

Of course it says it doesn't want your money. This monster Collider has some self-respect. It sends out Press Releases, like this one, all nice and cosy from September 5th, "CERN reinterates safety on eve of first beam" like on a snowy winter's eve with a baby first beam, http://press.web.cern.ch/press/PressReleases/Releases2008/PR07.08E.html

"A report published today . . ." it says " . . . provides comprehensive evidence that safety fears about the Large Hadron Collider are unfounded."

Comprehensive, no. Stuff not considered, lots.
Evidence, no. Theories, yes.
And which report?

Well the one the news stories based on this Press Release are trumpeting as though this was a new safety study just released. An assumption made by journalists too busy to read the CERN Press Release under a microscope. Here is what they mistakenly wrote about shortly after seeing the new CERN Press Release:

"a new report . . ." http://www.telegraph.co.uk/earth/main.jhtml?xml=/earth/2008/09/05/scilhc105.xml

Burried at the bottom is the old LHC Safety Assesment Group (LSAG) report from June, though still not identified as the subject of this Press Release. CERN's PR Machine is so good it could publish the Geneva phonebook as a safety report and it would still make headlines, No One Dead Yet, Claims CERN in a New Geneva Safety Report.

One safety study flows into another without being named and instead of four CERN physicists and one Russian who wrote the June LSAG report, it's "The report (still un-named) was prepared by a group of scientists at CERN, the University of California, Santa Barbara, and the Institute of the Russian Academy of Sciences." There is no one from the University of California, Santa Barbara that contributed, no groups except the CERN group and one Russian. Yes there is a scientist from UCSB, but he contributed to a different paper, "Astronomical Implications of Hypothetical Stable TeV-Scale Black Holes" and that report was done by a group of two, the UCSB guy and a CERN scientist.

The other safety reports are not exactly numerous, only one other LSAG report from 2003, CERN's first on the subject, based on the earlier RHIC safety report for a small low power U.S. collider in reply to Dr Walter Wagner's concern that micro black holes might be produced at the Relatavistic Heavy Ion Collider in Long Island, the 2003 LSAG report now the basis of the June 2008 update, the last update, the presumed subject of the CERN Press Release.

A few words later, "The papers comprising the report . . ." What report? What papers? Why not list all these papers and reports and provide hot links? Isn't this relevant in a Press Release? Or is CERN planning to send journalists Ask CERN Virtual Crystal Balls?

The only 2008 safety report was a single 15 page document undated, with one addendum of 11 pages, the total LSAG report. There was another much thicker report by two scientists on mBH, one from CERN, that was used to buttress the mBH section of the 2008 LSAG report. Those are all the papers, all the reports on safety this year from CERN. No doubt the whole kit and caboodle was presented to the CERN Scientific Policy Committee (SPC) of 20 unnamed scientists who CERN says are independent of CERN. If they pay for parking that settles it. Five out of 20 studied in depth "the 2008 report" meaning what report exactly? OK, say it was all they had, "and endorsed the authors' approach of basing their arguments on irrefutable observational evidence . . ." in the 2 documents submitted, the LSAG 2008 report, 15 plus 11 pages, and the GM Black Holes 2008 paper of 97 pages, finally clear from a read of the 5 page "SPC Report On LSAG Documents".

All this Press Release blather about 2 documents, previously published in June, previously reviewed in an undated SPC Report, the arcane subject of an September Press Release.

Go back a bit to the 5 page SPC Report. If the Press Release is a labyrinth, who claims the straight and narrow "irrefutable observational evidence"? What "irrefutable observational evidence to conclude that new particles produced at the LHC will pose no danger." These new particles have never been observed by CERN or anyone else. There is no evidence, only theories. But the SPC Report makes it clear that they weren't observing "new particles", but "irrefutable observational data on cosmic rays and on astronomical bodies". For journalists who aren't physicists what are they supposed to think? Don't worry about "new particles", we have observational evidence? We have observed these "new particles"? We saw them yesterday?

"The full SPC unanamously agreed with their findings." But why didn't the other 15 of the full SPC 20 study "in detail" the so-called report? Are they that busy, that the safety of CERN itself and their people and Geneva, isn't worth the full particpation of even one CERN hosted committee? But they all unanimously agreed with the select five and each other, perhaps on the very fate of the planet. 20 men decide for us all. The Black Hand Of Dr Cern won't let go of this Collider. It's mine mine mine! hisses Dr Cern, but we never see his face, only the blasted black hand groping for change.

On To September 10th And The Other LHC Machine: The CERN PR Department

The First Beam injection is an important test of LHC engineering. A single low power proton beam is going to circulate through the main 17 mile ring. It's not dangerous like some critics in the media are suggesting, with over-the-top headlines, The BBC calling it "Big Bang Day" for their live radio coverage on BBC FOUR.

Ordinarily CERN would be cringing at misinformed media hype. But it also plays 2 ways. A successful first test cancels fears that the collider is dangerous. Reacting to the media hype some other media outlets are making fun of the dangers, especially in Europe, a nice PR bonus for the machine.

CERN is turning this easy September 10th test into a bigtop LHC media circus, the perfectly safe collider. Hundreds of journalists will be on site for the thrilling 1/15 of normal operating energies single beam, 1/30 of eventual combined energies. The big CERN Dome will be the real hot spot, with all the collider action in up and down and side to side near-collisions of piled high plates from the giant free all day all you can eat buffet, if CERN doesn't forget to call the caterer. Warning, journalists are a grumpy hungry lot. Don't tell them to eat at the cafeteria. They could destroy it! If all goes well at the buffet, a bonanza of headlines the next day, Surprise, It's Not the End of the World. Not even close. Take your cue from Fermilab's own same day LHC Pajama Party, http://www.technewsworld.com/rsstory/64412.html?wlc=1220824563

CERN's direct competion is Fermilab's Tevatron collider, steady since the start of Run II at 0.90 TeV per beam or half the LHC First Beam attempt at 0.45 TeV. Still those small numbers are in Trillion electron Volts, enough to burn down the CERN Dome, easy, its only low-tech wood, but it is the media center for the day, so watch where you point that thing.

Still in the hunt for the Higgs, the Tevatron's in a last ditch attempt to beat the LHC. Due to run through to 2010 before being scrapped thanks to a recent financial bailout, $5 million from an anonymous donor and more cash this year from the U.S. Government's deep pockets or at least some loose change behind cushions in Washington, the venerable Tevatron has an extra year or two of life.

Way back when CERN's LEP collider was looking for the Higgs in its last days of 1999-2000, before 40,000 tonnes of it was hoisted away to make way for the LHC, CERN optimized and then pushed the LEP beyond its design energies. http://www.sciam.com/article.cfm?id=higgs-wont-fly

There was even a call to wait on demolition and press ahead with the LEP due to some tantalizing last minute results. They weren't heeded and for 8 years CERN has been in a vacuum doing no physics since then. Physicists at CERN have been understandably restless for years and now more so with the Tevatron still blazing. Another (unexpected) 'doubly strange' particle discovered a few days ago with energies higher this year and data optimized to the max, http://www.physorg.com/news139673506.html

Taking its cue from the old LEP do-or-die experiment, current Tevatron energy is 0.98022 TeV per beam, http://www-bd.fnal.gov/notifyservlet/www?project=outside the Higgs maybe a few more GeV down the road. Let's hope the old collider can take it. http://www.sciam.com/blog/60-second-science/post.cfm?id=fermilab-says-hey-wait-were-in-the-2008-08-08

With the Higgs in Fermilab's pocket, the LHC, ostensibly built to find the mother of all particles, might be a $10 billion irony, just another lonely financial black hole. CERN would definitely disagree. I'll make it easy for them here, since they don't bother responding to my blog articles or to my letters to the LSAG about potential hazards not analyzed by LSAG reports, like bosenova implosion/explosion from quantum state helium-4, or helium-3 produced by LHC ionization of helium-4, first proposed by me in a ScientificBlogging article, http://www.scientificblogging.com/big_science_gambles/superfluids_becs_and_bosenovas_the_ultimate_experiment
and now a part of the European Court of Human Rights suit on LHC safety; or thermonuclear fusion of this helium-3 also first proposed by me in The Science of Conundrums, http://bigsciencenews.blogspot.com/2008/03/almost-thermonuclear-lhc.html

CERN absolutely disagrees with everybody out there who hasn't got a CERN badge. Of course critical internal CERN Intranet emails are taken seriously before they are bounced into the not fully tested LHC thousand tonne beam dumps, where they've been known to smoke some graphite into methane, but don't tell anyone. It's top secret!

CERN has said there is other new physics out there as do collider happy physicists everywhere, maybe extra String theory dimensions and then oops micro black holes that oops might merge into a bigger mBH that might start accreting mass at 17,000 tonnes a year that might radiate some nuclear energy that might destroy Switzerland and might go on destroying the planet until it is destroyed, or so says a physicist, Dr Rainer Plaga, http://arxiv.org/PS_cache/arxiv/pdf/0808/0808.1415v1.pdf whom CERN has dismissed with an admirably quick but short 2 page argument printed on 4 pages, http://arxiv.org/PS_cache/arxiv/pdf/0808/0808.4087v1.pdf Plaga's paper on metastable quantum black holes is only theoretical, but can we relax when CERN's counter-arguments, all its safety studies are also all based on theories?

In the final analysis, the only practical analysis, CERN's implied LHC safety rests on one point rattling around somewhere behind their theories: So far no major threats have been found in the operation of tiny colliders using low energies.

For now it's theories versus theories, smoke and mirrors, from both sides of the question: Is The LHC Safe? Later this October with a big do-or-die totally unnecessary quantum jump in energy to the first LHC 5 TeV beam, way way more powerful than any collider's on the planet, that might all change.

Professor Sir Chris Llewellyn Smith of CERN says: "In any case, they will only send the hadrons in one direction this week. The collisions start in October. Until then, at least, we're not all doomed." Or last chance to visit Geneva or buy a Rolex. Quote from http://www.independent.co.uk/news/science/the-large-hadron-collider-end-of-the-world-or-gods-own-particle-921540.html

No, not the end September 10th, of the end of the world debate, maybe equipment failure, collider damage or something more surprising. Like basic nuclear physics they don't know about or maybe dismissed at the water cooler because everyone had another meeting on parking lot passes, the next big ski-weekend or New Dimensions in String Theory. (For the demonstration, please bring your own string and sharp scissors are recommended.)

If the LHC survives, then the first 10 TeV proton collisions later this year will be something to watch on the BBC's New and Improved Big Bang Day broadcast. Add a Rock Concert from the CERN Dome, for backgound music and intercutting into the boring bits. Hey Dr Brian Cox, Rock your Collider!

Let's have this one live on TV worldwide, or maybe Google Earth can get their just launched satellite cameras callibrated in time. About 500 miles up, Google Eye should be safe. Hope the DVD Live At The Collider makes it outta there. Might be the collector's item.

Stop CERN Euro Court Action Slips And Slides Forward

LHC Kritiks in Switzerland, Germany and Austria survived the first ruling on their case by the European Court for Human Rights, August 29th. So did CERN's Large Hadron Collider, which will go ahead while the court action continues. A stunningly quick decision by the ECHR only 3 days after the complaint was filed against CERN and its 20 member countries from the EC, denies any Interim Measures that would have forced CERN to suspend operations of the LHC.

Soon to be the world's most powerful atom smasher and the biggest and most costly science experiment ever, the $10 billion LHC straddles the borders of Switzerland and France, near Geneva. CERN the giant European nuclear physics lab has completed the 17 mile underground construction of the ring accelerator and is now in the first stages of start-up. It's goal is to unlock the secrets of the early Universe, through unparalled high energy collisions of hadrons, protons at first and then heavy lead ions. Critics believe that the LHC could pose enormous dangers to the planet.

Markus Goritschnig, a spokesman for LHC Kritiks said, "This quick decision of the court to dismiss the claim for Interim Measures is not a negative sign as such. The Court is studying the whole appeal in detail now. Only the claim for Interim Measures was rejected, not the appeal itself." The Court gave no reasons for dismissing the preliminary injuction to stop LHC operations.

"The case before the European Court of Human Rights," said Dr James Gillies, chief spokesman for CERN, commenting on the Court case in the Telegraph, "contains the same arguments that we have seen before and we have answered these in extensive safety reports."

Bosenovas haven't been addressed by CERN. All 12 points in the LHC Kritiks arguments are being considered by the ECHR, including Bosenovas. A new risk of a Bosenova produced during collider operations that might destroy the LHC, was first raised in the on-line science magazine ScientificBlogging in an article July 2nd, by Alan Gillis. Other well-known safety hazards have been studied in the latest CERN LHC Safety Assessment Group report, theoretical objects and dangers that might be produced at the LHC, like micro black holes destroying the planet. MBH is the main focus in the Court suit. CERN concludes there is no risk.

LHC Kritiks strongly disagree on the level of risk and CERN's claim that they have addressed it. "In the complaint", said Markus Goritschnig, "we took all the safety arguments into consideration that were given by CERN in their standard reactions to the global risk. They will have to produce a better LSAG report."

One of CERN's chief critics on mBH is the eminent scientist, Dr Otto E Rössler. He has been linked to the Court challenge, though he is not directly behind it. There are three principal signatories to the suit, one each from Switzerland, Germany and Austria. In the suit Dr. Rössler's theories on mBH figure prominently. In answer to Dr James Gillies, he told me that CERN still has not disproved his general relativistic theory on mBH or proved that neutron stars are immune to mBH because mBH don't exist. Dr Rössler said these, the most dense stars, are not attacked by mBH because they are protected by their own superfluidity, so mBH pass through them as there is no friction. MBH can exist in space, he insists. CERN has no proof one way or the other. Dr Rössler said, "This unproven argument does not impart any security onto earth as CERN alleges."

Dr Rössler added that there is further confirmation of his theory that mBH do not evaporate, contrary to what Professor Stephen Hawking states, through his Hawking radiation theory. "I just learned about an earlier proof of non-evaporation given by Vladimir Belinski, Institute des Hautes Etudes Scientifiques at Bures-sur-Yvette, France, in Physics Letters A. (Vol 209, p 13)

The authors of the Euro suit have included a new study on the mBH question, not considered in the LSAG report as both are recent documents. The paper by Dr Rainer Plaga, a German physicist, that supports Dr Rössler on possible mBH production and dangers, uses quantum physics arguments as CERN does. Markus Goritschnig thinks that Dr Plaga's work is a compelling contribution to the argument for dangerous mBH. "Plaga says the first consequence of producing black holes in lower dimensions would be a disastrous explosion. Then the semi-stable black hole would intensively radiate, consuming 17,000T of material each year. It would be unremovable, undestroyable, and surely endanger the planet as a whole."

Dr Rössler is due to meet with the Swiss President, Pascal Couchepin, this fall on LHC safety issues. According to a spokeswoman for the ECHR, "The proceedings before the Strasbourg Court are expected to take several years."

Suit Alleges CERN In Violation Of Human Rights

Yesterday, a group of LHC critics filed a suit against CERN in the European Court of Human Rights, in Strasbourg . The authors of the suit are physicists, professors and students largely from Germany and Austria, who feel that the operation of the $10 billion Large Hadron Collider near Geneva, poses grave risks for the safety and well-being of the 27 member states of the European Union and their citizens. The Rule of Law, the suit states, is also threatened. The legal arguments that define the legitimacy of the suit appear clear-cut, and have been crafted in German by a well known Professor of International Law, Adrian Hollaender.

The arguments for several major risks that might develop into wholesale disasters are based on papers from various physicists and a risk assessment analyst, whose conclusions will be examined by the court as well as counter-arguments by CERN. It's a question of theories versus theories. The outcome is anyone's guess, but a cogent risk analysis could be the deciding factor. The suit highlights the possible production of Micro Black Holes, which could be a pollution hazard or combine and destroy the LHC. In the worst case, mBH could start consuming the planet, producing dangerous radiation.

MBH are admitted as theoretically possible by CERN. Indeed CERN anticipated large scale production of mBH, but lately has refuted the possibility and denied that they could be produced at the LHC, unless there were extra dimensions as postulated in String Theory. In that case CERN says mBH would be harmless, evaporating quickly due to a theoretical Hawking radiation, though this radiation has not been detected from black holes in space.

Bosenovas are a new risk theory in the suit, besides the better known Strangelets and Lowered Vacuum State theories. Unlike the others there is some experimental evidence for a Bosenova, but this phenomenon of implosion/explosion has only been produced in small groups of atoms of Rubidium-85 in an ultracold state, a Bose-Einstein Condensate.

What might occur at the LHC, is a new type of Bosenova from what amounts to a BEC used there as a coolant, an ultracold Superfluid Helium II, of about 60 metric tonnes in the LHC ring, and a further 60 tonnes of somewhat warmer Superfluid Helium I in refrigeration plants on the surface connected to the subterranean main ring. Whether possible or not is unknown, no experiments having been done by CERN to rule out the possibility, nor any theoretical model studies. The Bosenova risk was first raised in an article by Alan Gillis in the on-line science magazine, ScientificBlogging, July 2, 2008, "Superfluids, BECs and Bosenovas: The Ultimate Experiment".

The first full proton beam injection into the LHC is due September 10th. As further studies and experiments required to assess risks are a long way off, and even a decision on risks as presented by the plaintiffs could take the European Court some time to evaluate, the authors of the suit are asking the court for a speedy granting of Interim Measures. The LHC should be shut-down pending the Court's ruling. The argument that the LHC be limited to no more than 2 TeV energy overall, similar to Fermilab's Tevatron collider design energies, they exclude from the Court's consideration.

A similar suit is before the US court in Hawaii, launched by Dr Walter Wagner and Dr Luis Sancho, against CERN and Fermilab, court in session September 2nd.

LHC Start-up To Shut-down 2008

After the Olympics, the next big thing is the international Large Hadron Collider. There's a lot of excitement at CERN. The first injections, and without a hitch, of low energy protons shot through an eighth of the 27 km LHC ring. Back to back for this weekend they're doing it again at 0.45 TeV with the anticlockwise beam. It's an important preliminary test, kicking the protons from the pre-accelerator loops, into the unknown. At this point CERN is confident there is nothing to worry about. The energy is only half of the currently most powerful collider, Fermilab's Tevatron, in Batavia, Ill. So, CERN's probably right, this time. Higher energies will be the real test.

Now for the news, major media aren't covering, from the current Strings 2008, a CERN conference, and not only on String theory. It's another window on CERN that is fascinating.

Even at 1% of design energies, as Lyn Evans, Project Director, said August 18th in his talk, on LHC Machine Status, we'll be in new territory. He also confirmed that the first beam right around the main ring is still set for September 10th, as announced last week.

There's one problem Evans said quickly, a turbine needs replacing in Sector 6-7, but it won't delay operations. Once another test is done for the other beam later in September, CERN plans to go ahead with 5 TeV runs before the standard winter shutdown. A Russian scientist, Alexander Vodopyanov of the Joint Institute for Nuclear Research (Dubna), said recently in RIA Novosti World, that he's heard that the LHC will be inaugurated October 21st, which supposes that the collider, will by that time have had one test run at least. Though beam collisions at 10 TeV, probably will start later. CERN is in a hurry though, having cancelled earlier plans for a gradual ramping up of beam energies. Going from a known quantity, suddenly into the unknown is a risk, and totally unnecessary. The big rush is due to three years of delays, construction and equipment problems.

Seems they would even have skipped 5 TeV and gone straight to 7 TeV beams this fall, as Evans said the collider wasn't ready for the design energies, as some magnets had been lying around for two years, and were found to require retraining for higher energies, though they were previously trained, this batch from some other supplier. Those will be retrained during the winter shutdown, so they can all go skiing. Mount Blanc is only a proton away. That's not official though. Ski report widgets and desktop ski weather icons and live webcam links to the best ski resorts are all over CERN desktops and laptops. Ski weekend emails fly like alarm routines.

Magnets have to sit up, bark and rollover, as they say at Fermilab. Twelve hundred 15 meter ones at about a million dollars a pop, thousands of smaller ones. But Evans added they were proceeding with care, with some magnets not fully trained, not pushing them beyond 5 TeV, as there are always some protons lost from the beams, and that can cause magnet quenches. As we know from the Tevatron, quenches can crash down the entire collider. Sometimes beams are lost, potentially a dangerous situation.

So September 10th, 21 days to go, is not the BBC's "Big Bang Day", as they're calling it, on their live Radio Four broadcast, starting at 0:8:30 BST. No need to panic yet. Try again later this October. For all you fans of micro black holes, you'll have to wait for them too. CERN's not convinced they'll show up during proton collisions. If they do, Dr O. Buchmüller, speaking on The Search for New Physics at the LHC, said at Strings 2008, after the Evans presentation, that if they show up they would be within SUSY parameters, and their signature would be clearly obvious. Keep your fingers crossed so they aren't too obvious.

Make a date to watch the September 10th LHC Sparks and Quarks, starting 0:8:30 BST, firing of the First Beam an hour later, like on BBC Radio Four, either on Eurovision, if you have a feed or can buy an Internet pass for this one. Or if you're broke after blowing $10 billion on the LHC, watch it for free on CERN's tiny TV Live Webcast, better in Flash if you have internet lite, but a fast machine.

The just-ended Strings 2008, the best in arcane viewing, even if you're a physics fanatic, was a live webcast on the same CERN url daily this week. Earlier talks from Strings 2008, you might have missed, including the must see Evans and Buchmüller talks, should be available as videos a few days late on this same CERN url, see below.

From First Test To First Beam To First Collisions

CERN's image (above) of last weekend's first proton bunch injection, raises some questions for those who aren't particle physicists. If you read the CERN descriptions of the particle beam and bunches of protons, they look nothing like this.

Ordinarily at design energies, CERN states there will be 3,000 bunches of protons in the beam, and numbering overall anywhere from 100 billion to the trillions of protons, depending on how much luminosity the physicists at the LHC would like for each experiment. The pictured bunch according to SciAM is 5 million protons, a far smaller number than would be usual, which would be at least 100 million protons per bunch. And CERN always describes their beams as less than the thickness of a human hair, and each bunch about 5 cm long. What we're seeing with this first bunch is a hot ball of protons, with a big halo and tail, at about 7.5 mm on the Y-axis, and with the halo included, about 11 mm overall, more like the width of your baby finger.

There's nothing wrong here, as this is typically what you get from the low energy 0.45 TeV SPS pre-accelerator that feeds the LHC. Further focusing of the beam will occur later, to produce needle-like bunches, through collimators throughout the main ring. But the halo is worth looking at. It's well understood this is mostly an electron cloud, generated through interactions of these accelerated protons and extremely high magnetic fields from the superconducting di-pole magnets.

But in the LHC the initial halos, that are cleansed later and focused, show some foreign matter in the beam cryostats which is burning, and this in the best vacuum that CERN can produce for the beam lines, a greater vacuum than is found on the Moon.

Recently, Katherine McAlpine, a science writer working for CERN, put it this way. ". . . with that first beam, they're going to be getting so much more data coming out from those protons running into things that are in the beam pipe than they're getting from cosmic rays coming in from outer space right now that the detector people will have a lot more information to work with calibrating."

Of late she's become well known as AlpineKat through her rap video, "Large Hadron Rap", with CERN back-up.

Besides some collider debris, electron cloud production at the Proton Synchrotron and the Super Proton Synchrotron has been an unresolved problem, especially the proton scattering which comes with an unfocused beam. Other pre-accelerators have the same problem.

Looking back to what Lyn Evans said at Strings 2008, there's an interesting effect that might be seen on September 10th, during the First Beam right around the collider ring.

As some magnets are not properly trained, they won't be ideal superconductors like the other magnets, that will be at 8.33 Teslas. Their magnetic fields will be somewhat weaker and so the First Beam of protons will pass through various field strengths around the collider. This also affects the Superfluid Heliums that circulate through the magnets and cool them and the cryostats. As Superfluid Helium is considered to be a Bose-Einstein Condensate, it has been demonstrated in another BEC that an abrupt change in magnetic fields starts the Bosenova implosion/explosion.

No CERN experimental studies or theoretical analysis has ever been produced on this safety issue by CERN. The recent LSAG safety report by CERN ignores this possible risk that might destroy the collider.

There should be some news this weekend on another test. The counter-rotating beam, like last weekend's test will be injected this weekend, probably with similar success. The next thing to watch is the September 10th First Beam, where there is more risk of failures in engineering and equipment. Look for a follow-up article here on what CERN might discover, when it's too late.

Katherine McAlpine also said, in line with earlier reports from CERN, " . . . on September 10th they're really only going to have one beam going around, so they're not going to have collisions until they project about two months later after startup."

So around November 10th for the first particle collisions at 10 TeV.

CERN Confirms Big Bash

If there's no big crash, CERN says the Collider Inauguration will be October 21st, as Vodopyanov said. 10 TeV Collisions are scheduled before winter shutdown, CERN says again, confirming what McAlpine said. And I was right about the second kicker magnet test. No problems. There was a bit more action from one of the smaller forward detectors, the VELO, part of the giant LHCb detector. The protons knocked through part of the VELO array, and CERN captured the first particle tracks in a series of images, showing at least that this bit works. A relief, these card modules are supercomplex. See the preliminary data and beam schedule on this CERN summary page.

LHC News Update

Well Fuk, over to you.

Right Brian. Over on Earth, 'Red Button Day' is fast approaching. That's when they push the big red button at the Large Hadron Collider.

It's finally a go, right Fuk?

We make it a preliminary feed. We're getting some Russian satellite interference. We're filtering now. Gillies at CERN is on top of it.

Wasn't he on top of it for June? Fuk?

That was full cooldown, Brian.

So we got full cooldown, Fuk?

No Fuking way. They're almost there.

Fuking glitch factory, Fuk? Weren't they gonna hit that Fuking button 3 years ago?

That's affirmative, Brian. But when they do, they're gonna hit a Fuking Home Run.

Hope you're right, Fuk.


The real down to earth story is the Russians have scooped CERN on start-up of the LHC. RIA Novosti World says the collider "will be officially unveiled October 21". The source is a Russian scientist, Alexander Vodopyanov of the Joint Institute for Nuclear Research (Dubna). CERN has been awash with start-up rumors lately, including one in The New York Times, and hasn't commented.

James Gillies, CERN's PR Director, reported in CosmicLog MSNBC, did announce that the timing of the first beam injection will be sometime during the first 2 weeks of September. "The machine is basically cold now." See for yourself. Click on LHC Cooldown Status Live, on this page, from a column of KEY CERN SITES on your right, only 5 of 8 sectors are cold enough, at 1.9 K . But this first injection is for only one beam into one sector of 8, basically a test of one of the Injection Kicker magnets that kicks a proton beam into the main ring from the PS and SPS pre-accelerators. This will be the clockwise beam, the counterclockwise beam test should be a month later. The beam energy isn't specified, but it will probably be 0.45 TeV, which is what the pre-accelerators deliver to the main 17 mile ring, where beams will be further accelerated to 5 TeV, maybe in October as Vodopyanov says, just before the official inaugeration.

CosmicLog also has some useful updates on a rival Fermilab search for the Higgs Boson, some ZZs turning up, yawn. And the Wagner/Sancho suit, to be heard in court on September 2nd. It could be dismissed then or an injunction could be granted to delay LHC start-up. Or proceedings could drag on. Probably the Hawaiian Court will say they don't have jurisdiction.

And all the fuss on the latest LHC Rap Video, not enough juice to power a hearing aid, at 0.0000000000003 GeV. The Cernettes Channel on Youtube can't be beat.

Lately too, you might want to see a dazzling gallery of 28 hi-res images of the LHC by CERN photographers on The Boston Globe on-line edition's Big Picture.

STOP PRESS August 7, 2008

It's official. CERN announced the first attempt to circulate a beam of protons through the LHC ring will be September 10, 2008. The beam energy is what the pre-accelerators can deliver, that is 0.45 TeV. The target is still 5 TeV per beam later this year, with collisions possible before the planned Winter shutdown.

The big event will be on Eurovision, but elsewhere you'll need a paid on-line account with them. There's a big media circus being carefully planned for hundreds of journalists descending from the skies or driving in. The good news is the rest of us will be able to watch it live on up to 4 CERN Webcast Channels for free. Thanks to all at CERN. Don't forget to stock up on your Collider Donuts and don't miss this. If you're worried, it's still too early to be really worried, only a low energy single beam run. Still the LHC has never been tested like this. Expect some sparks and quarks.

The initial test of an Injection Kicker magnet into one sector is way ahead of schedule, set for this weekend. This must be an LHC first. Ahead of schedules and rumors? Amazing!

Make a date to watch the Collider Show here, Wednesday September 10, 2008. It's five hours later in France if you're in New York. There's a CERN LHC LIVE WEBCAMS spot on your right. Click on CERN Live Webcasts. Next one is August 18, 08:00 or 3 AM in NY, lectures on String theory, "Strings 2008".

LHC Sci-Fi And Critics Buried In The Blogosphere

The British ATLAS Team inspecting their Stargate Portal, the higher-dimensional ‘shipping container’ ready for activation, beating the American LOST Team by 2.2 years. The Russians were the first to crack the top secret potential of the LHC Time Machine, but forgot to commercialize it.

Now the American LOST Team has the Hollywood edge, with millions watching every week, and an Internet frenzy that eclipses anything on real science. Fifty million hits on one LOST fan site alone. The LHC Money Train smokes, while mighty NASA bites the Martian dust.

It gets goofier with the new Dan Brown movie, Angels and Demons, and Tom Hanks, scheduled for launch May 15, 2009. Stealing antimatter from CERN to make a bomb to blow up the Vatican. CERN did produce antiprotons with the old LEP and even a tiny bit of antihydrogen, enough to blow up a jumbo cup of movie popcorn, though they’re not planning to produce any with the LHC, unless by accident, in which case it might blow up and uh-oh fuse some helium.

So the interest in the LHC is big, sideways. Considering its real world unknown potential to blow itself up with a super bosenova, and maybe Geneva, or produce a runaway black hole that might devour the planet, or strangelets, or magnetic monopoles or wormholes, there’s, oddly, little enough real interest outside the physics community.

The problem is, that apart from a few critics with scientific credentials who have gone public, those with some international clout, either support the LHC, like Stephen Hawking, or are working directly or are collaborating with CERN, about 8,000 or half of all particle physicists. The others are teaching or working at other labs. Some have their doubts about the wisdom of going ahead with the LHC, but they’re either obliged to keep them private to protect their jobs and reputations, or they voice their concerns during coffee breaks at committee meetings. For those physicists outside the CERN loop, CERN invites them to contact Michelangelo Mangano, a CERN physicist and quantum spin doctor, who handles serious objections at the LHC. He must be good. Complaints go in and like in a black hole, they never come out again.

With the mainstream media unwilling to investigate possible dangers at the LHC, that leaves the field open for anonymous and amateur scientists to criticize the LHC, about a dozen major websites and blogs geared to monitor the LHC, and comments posted on hundreds of news sites that run articles on the LHC, even on social bookmarking sites and anonymous blogs and blogs within blogs. Comments run from the abysmally dumb, to panic-stricken, to rumor-mongering, to honest complaining or just having fun with doomsday, though there is some erudite analysis, tantalizing but not easily verifiable. Here are a few worth reading.

From Physicsworld: vbarashkov June 24, 2008 2:58 PM
I doubt that is how a black hole can be formed, considering that as we know so far it takes an entire star to form one. Not only that, but for a black hole to form exactly how much must the two atoms be compressed. Certainly a lot more than they can be in a head on collision even at near twice the speed of light. If I had 20 ton iron sphere, and I compressed it to fit on a tip of a needle, the only thing it would do is explode with enough energy to destroy the entire planet. . .

Anyone seen a black 20 ton iron sphere? It was here a second ago? Never mind, Val found the vodka.

From Geekology: VtFarmboy - February 12, 2008 11:22 AM
I think Mr. Scott needs to get back to the enterprise. He's needed the Klingons are attacking and the warp drive dilithum crystals are decaying.

And Spock. Is that new compression algorithm ready? We need to beam up the LHC before it blows up. Professor Rössler wants it on the Moon right now.

From The Great Beyond, BlogsNature: Walt 06-18-08 01:00 AM
. . .The CERN-LHC website Mainpage itself states quote: "There are many theories as to what will result from these collisions..." This stunning admission is because they truly don't know what's going to happen. They are experimenting with forces they don't understand to obtain results they can't comprehend. If you think like most people do that 'They must know what they're doing.' you could not be more wrong. The second part of the quote reads "...but what's for sure is that a brave new world of physics will emerge from the new accelerator..." A molecularly changed or Black Hole consumed Lifeless World? The end of the quote reads "as knowledge in particle physics goes on to describe the workings of the Universe." These experiments to date have so far produced infinitely more questions than answers but there isn't a particle experimentalist physicist alive who wouldn't gladly trade his life to glimpse the "God particle", and sacrifice the rest of us with him. . .

Walt has it right. Here is the actual embarrassing CERN webpage, Our understanding of the Universe is about to change...

From NatureNews: David Wenbert 06 May 2008
. . . 4. Perhaps the unqualified legacy of monumental failure and waste exhibited by the high energy and plasma physics community is instructive here. After more than 50 years of building ever larger and more powerful colliders and plasma reactors, at a cost of untold Billions of dollars, NO useful scientific breakthroughs have ever been recorded from either such device, and both a Fundamental Understanding of Matter, and Controlled Fusion Energy remain totally elusive. The abject failure of particle physicists to have achieved their objectives (i.e. discovering the Higgs Boson) with prior collider experiments - although widely predicted to have done so - indicates the low reliability of their certainty in the outcome of these experiments. Consistently wrong, over decades, in their assertions that 'the last big machine' would illuminate the structure of matter - or ignite a controlled breakeven reaction, for that matter - leaves us with no alternative but to conclude that the same physicists may be no more accurate in predicting the behavior of 'the next big machine. The math doesnt fix this, since each such project had 'good math' to contend it would meet its scientific objectives, and yet, repeatedly, failure ensued. The rich, deep, and unbroken record of failure in these "Big Physics" projects is a Red Flag that the warnings from the fringe on potential distasters should be heeded. The physicists who propound the reliability of their assumptions have yet to be proven right once, whereas, the alarmists only need to be right 'once'. The Precautiionary Principle would seem wisely applied in these collider debates.

Read the thread and Wenbert’s full comment, in response to a previous comment by Richard Dawson who wrote to CERN and got some answers he quotes from the CERN letter.

One important point on micro black holes, received no comments, but is worth another look. The unnamed CERN source wrote, “But since, in case they (mBH) really exist, there will be millions produced, this means that indeed a few of them would be stopped within earth and start accretion. This however does not mean that they will crush the earth.” This is the point most commentators have been worried about. The odd thing is that at first CERN ignored the possibility of black hole formation, then embraced it publically as the LHC Black Hole Factory, while in their latest safety report, the LSAG is busy swatting mBH as though they were CERN’s famous TeV mosquitoes. That embarrassing Safety at the LHC webpage has been deleted, replaced with a summary of the new LSAG report where Einstein has been resurrected, and therefore “. . . it is impossible for microscopic black holes to be produced at the LHC.” Mosquitoes however, linger on Are LHC Collisions Safe?

The best analysis ever was made inadvertently, by The New York Times, when they called the LHC, The Large Hardon Collider, which fits in well with Big Bang Theory, on everybody’s mind since the hit TV show.

Seriously, there is one dissenting group of physicists at CERN, forced to do retro cabaret or else get lepton, none other than those sexy control room bottoms from the biggest collider ever, Les Horribles Cernettes.

Superfluids, BECs And Bosenovas: The Ultimate Experiment At The LHC

The first BEC, a rubidium-87, at 3 temperatures, 400nK, 200nK and 50nK, each pile of atoms 1 mm wide, activity greater nearer absolute zero, NIST 1995

In a familiar world of solids, liquids and gases, we find the fourth state of matter, the plasmas of lightning to the aurora borealis and fluorescent tubes at the office. Further out, minor phenomena becomes the big event in space, our shining stars are plasma being fused producing light. Not until 1924 was a fifth state of matter considered possible. Intrigued by quantum statistics, invented by the Bengali physicist, Satyendra Nath Bose from observations of light, Einstein applied Bose’s work to matter. The Bose-Einstein Condensate(BEC) was born. Was there any truth to the theory, Einstein himself wondered, that matter that could condense at ultracold temperatures into something new?

Einstein’s theory was left hanging, as a mathematical artifact, until 1938. Fritz London, a German theoretical chemist and physicist, working on helium at the same time as the Russian Pyotr Kapitsa who discovered its superfluid state at just under 2.2 K, found it behaved like Einstein’s theoretical BEC. Subsequent research confirmed London’s insight. Both stable isotopes, ordinary helium-4, and the rare helium-3 at much lower temperatures, are quantum superfluids, behaving like matter-waves or superatoms, undifferentiated matter with vastly different properties from their gas state or their ordinary bottled fluid state. Now scientists had a way of studying laboratory tabletop quantum physics. These, the only two superfluids known with zero viscosity, have sparked intense interest, helium-4 a bosonic superfluid and helium-3, a fermionic superfluid. Bosons are force carriers like photons of light and fermions are the matter we can touch. A gateway opened which eventually led to the laboratory production of other BECs when finally ultracold states could be induced, starting in 1995.

Viewing superfluid helium in action, demonstrates the baffling counter-intuitive nature of quantum fluids and other BECs. Some of the stunning properties of superfluid helium were observed if not understood back in 1908 when the Dutch physicist, Heike Kamerlingh Onnes, cooled helium-4 to -269 Celsius. Not only was there no resistance to flow, the superfluid could climb the walls of the vessel, like a film, always 30 nanometers thick, defying gravity, or pour through the smallest hole or fissure, or leak through some apparently non-porous matter.

Further studies showed that this superfluid, now called Helium II, behaved as a two-fluid model, partly in a low energy ground state, and partly in an excited state. With a little added heat and manipulation of the superfluid, an interaction of the two states was enhanced, producing a fountain effect, as though 2 fluids existed.

In our own Sun and countless other stars, hydrogen fusion produces helium, the second most abundant element, and is in turn eventually fused by steps into carbon-12. On Earth there isn’t much, a trace atmospheric gas but found in quantity up to 7 percent in some natural gas. It’s produced by nuclear decay, as from radium and polonium, dangerous alpha radiation releasing, in fact bare nuclei of helium that eventually pick up electrons and form stable helium isotopes.

Given an electric charge, helium can fluoresce like neon. Even rarer molecules of helium-3 have been produced in helium-4 during ionization. Superfluid helium is also a superconductor, 30 times more efficient than copper as well as a thermal conductor 300 times that of copper. And both helium-3 and helium-4 have been cooled to near absolute zero, helium-4 retaining its superfluidity, helium-3 crystallizing, yet still capable of movement like other BECs. Adding enormous pressure of 25 atmospheres and more, forces even helium-4 to act like other BEC ‘solids’.

If superfluid helium can tell us a lot about other ultracold BECs now being studied and produced by over 200 research teams worldwide, then BECs that also appear to be superfluids and have two coexisting states like the two fluid state of superfluids, could show us how superfluids behave. It’s more than satisfying the curiosity of pure research. BECs have been turned into atom lasers and BECs have produced bosenovas, an inexplicable phenomenon where BECs explode, releasing more than the energy present in the system and where about half of the BEC sample literally vanishes without a trace. Fascinating and worrisome in any lab working with small amounts of BECs, but superfluid Helium II BEC is being used in great quantities as a coolant in certain nuclear reactors and particle accelerators.

The possibilities of a giant BEC bosenova produced in superfluid Helium II haven’t been investigated. The matter is urgent as 120 T of superfluid Helium II are being used at the Large Hadron Collider at Geneva, whose energies far surpass any other collider’s, not only beam energies, but RF applied, extreme Tesla Fields by superconducting magnets, and electrical energies equivalent to the consumption of Geneva, powering the 27 km ring system. Startup of the LHC at 5 TeV per proton beam has been delayed to this September but for other technical reasons.

The problem too, is that BECs are new and strange. It wasn’t until 1995 that an ultracold BEC was produced by new methods of supercooling, in this case applied to a gas of Rubidium-87 to bring it near absolute zero. For physics it was a sudden explosion in the quantum world. A new field of study, Condensed Matter Physics, a new state of matter positively confirmed, but far from understood. Matter acting as one giant atom with the properties of a superfluid. Shared Nobel Prizes awarded in 2001went to the team leaders at JILA, the joint NIST project with CU-Boulder, Carl E. Weiman and Eric A. Cornell. A third share in the Nobel for a sodium-25 BEC developed independently went to Wolfgang Ketterle now at MIT. Research at MIT is on a massive scale with several big BEC labs, working in part on BEC atom lasers. Don’t worry, Ketterle has said, atom lasers only work in a vacuum and would only travel a meter without one. Nevertheless matter-wave lasers are bound to be improved. There’s always military interest and funding.

A bosenova explosion of rubidium-85, from a new burstmovie by NIST, 2008

What astonished some physicists was another BEC event in 2001, well beyond anything anticipated. The BEC discovery team at JILA produced a new rubidium-85 BEC. While an electromagnetic field was applied to cause a stronger attraction among the BEC atoms, the BEC started to shrink and then exploded like a supernova. The result was a release of particles in various streams, leaving behind a much smaller BEC remnant. The thermal energy released was greater than the energy in the BEC and about half of all the thousands of atoms of the rubidium-85 disappeared. The effect was at first nicknamed the bosenova, and still a total puzzle to this day. After 7 years of study, the latest research on whatever goes on in a bosenova, now referred to as a BEC loss, needs a “new microscopic BEC physics” to explain it, says N.R. Claussen et al of a joint BEC team at the U of Colorado at Boulder, in a paper published in February this year. A second team at UC-Boulder led by Elizabeth A. Donley published the following month, also could not account for the bosenova phenomenon nor the apparent loss of atoms.

Though the bosenova effect is staggering in its repercussions for the Standard Model, none of the more than 200 teams experimenting with BECs appear interested. The only study groups working seriously on bosenovas are those at JILA. Other research teams are looking for new BECs and a few are looking for applications of BECs to create things like better atomic clocks, interferometers or even studying light by teasing BECs with lasers to slow light down or stop it! In the future, quantum computing might use BECs and lasers. BECs could be big business.

What happens next at the LHC will be the next big experiment in a superfluid Helium II BEC. It’s not part of the design parameters, as physicists assume that the helium will be stable based on its use in the much smaller, much less powerful, up to 250 GeV per beam, RHIC collider in Long Island, NY. CERN’s interests lie in producing the Higgs boson at the LHC, perhaps micro black holes and quark-gluon plasma. Even in the much awaited CERN safety study released last month, there’s absolutely nothing on a possible bosenova implosion/explosion. Of course to test the safety of the enormous LHC to handle foreseen and unforeseen events you’d need another disposable one. But at least it is possible to subject Helium II to some of these high energies and hadron beams as a test. Not at the low energies of the RHIC, but at Fermilab’s Tevatron, currently the most energetic collider with 0.9 TeV per beam, though still far short of the power of the monster LHC at ordinary operating conditions of 7 TeV and ultimately 1,150 TeV collisions of lead ions at nearly twice light speed. Helium II could simply be used as a target by Tevatron beams to see what would happen, besides being exposed to high and fluctuating Tesla fields, ionized by electrical currents, subjected to some of the extreme conditions anticipated at the LHC.

The LSAG safety review at CERN, even their new report, is still a 4/5 majority internal assessment, and with an independent SPC Report/review of that review that’s still a CERN committee of 5 physicists, though the mainstream media is content with the CERN press releases, ‘No Danger That The LHC Will Destroy The Earth’, about everywhere. Though now black holes are now unlikely, but previously predicted to occur rapidly by CERN in the ‘LHC black hole factory’, but initially ignored, until a physicist wrote about the possibility in a letter to Scientific American that sparked the initial 2003 CERN safety assessment. There’s hard science and there’s French farce. Which one are we getting? Pushing the LHC big button as a test is a risky way to go. CERN has always insisted that small amounts of hadrons can’t do very much, but there’s an enormous amount of energy in the LHC and 120 T of BEC superfluid. There’s still a suit in the Hawaii courts to delay LHC startup because of safety concerns like black hole and strangelet production. Lately and since I first considered the possible dangers of superfluid helium in my article of March 7, 2008, ‘The Almost Thermonuclear LHC’, the plaintiffs, Dr Walter Wagner and Luis Sancho have announced they will seek an addendum to their suit to include bosenova risks at the LHC.

Seven years after the rubidium-85 BEC produced the first bosenova, we still don’t know what happened to half of the Rubidium-85 atoms that disappeared.
