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.sciencedaily.com/releases/2008/09/080904220342.htm

"A new report . . ." http://www.universetoday.com/2008/09/05/new-report-lhc-switch-on-fears-are-completely-unfounded/

"A new report . . ." http://www.eurekalert.org/pub_releases/2008-09/iop-lsf090408.php

"A new report . . ." http://www.physorg.com/news139810863.html

"A new report . . ." http://www.newswise.com/articles/view/544021/?sc=rssn

"A new report . . ." http://www.newkerala.com/fs/b/ai-1621.htm

"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."
