Science: LHC Shut Down By Transformer Malfunction 293 comments
Ortega-Starfire writes "A 30-ton transformer in the Large Hadron Collider malfunctioned, requiring complete replacement on the day the LHC came online. No one at CERN reported any problems, and they only released this data once the Associated Press sent people to investigate rumors of problems. I guess it's hard to just sweep a 30-ton transformer breaking under the rug."

holy_calamity writes "CERN have released images of the damage done to the world's most powerful machine, the Large Hadron Collider, when an electrical fault caused a helium leak. New Scientist has posted them, along with explanations of what you can see. The sudden burst of gas shifted some of the huge superconducting magnets by half a meter, causing at least $21 million in damage."

Science: Large Hadron Collider Struggling 371 comments
Writing in the NY Times, Dennis Overbye covers the birthing pangs and the prospects for CERN's Large Hadron Collider (which we have discussed numerous times). "The biggest, most expensive physics machine in the world is riddled with thousands of bad electrical connections. [And] many of the magnets meant to whiz high-energy subatomic particles around a 17-mile underground racetrack have mysteriously lost their ability to operate at high energies. Some physicists are deserting the European project, at least temporarily, to work at a smaller, rival machine [Fermilab's Tevatron] across the ocean. ... Technicians have spent most of the last year cleaning up and inspecting thousands of splices in the collider. About 5,000 will have to be redone... Retraining magnets is costly and time consuming, experts say, and it might not be worth the wait to get all the way to the original target energy [of 7 TeV]. Many physicists say they would be perfectly happy if the collider never got above five trillion electron volts. Dr. Myers said he thought the splices as they are could handle 4 [TeV]. 'We could be doing physics at the end of November,' he said in July, before new vacuum leaks pushed the schedule back a few additional weeks. 'It's not the design energy of the machine, but it's 4 times higher than the Tevatron,' he said."

I like their quote "The cost of the work will fall within the Cern's existing budget" though it does make me idly speculate on the size of their budget and how large a secret fortress I could build with it....

14 million quid is the price of a decent footballer. It's really not that much money at all. CERN's total budget runs to something like £700 million per year.

You'll can probably build some undergroung fortress with some 20km or 30km of radius, I guess. With a doomsday machine still on budget!

"The media portrayal of the LHC experiments has been branded as irresponsible and sensationalist by psychologists - especially since the death of a 16-year-old Indian girl, who killed herself after being distressed by the coverage on an Indian news channel." [trinitynews.ie]
The threat to human life from people like KDawson posting sensationalist anti-LHC garbage to places like /. is real and documented. At least one person has actually, demonstrably died due to the precise behaviour that KDawson is exhibiting on this story.
The supposed threat from the LHC, on the other hand, is a fantasy made up and promoted by irresponsible, money-hungry media shills like KDawson to sell ads.
The LHC is safe. People like KDawson kill.

At least one person has killer herself because she went into an irrational panic, and did something stupid and rash. That's often a sign of psychological problems.
Yeah, the media coverage has been sensationalist and dumb. But it didn't kill anyone.

No you've got it all wrong. Its 'And then, we will be stuck in the event horizon, but with my new flux capacitor I can bring two person through into a parallel universe across the twenty-fifth dimension. One of them has to be me, because only I can control it and I was thinking perhaps you... but no it would mean staying in a confined space without light for hours
several hours later: Gosh this parallel world is the one just like ours but where the laws of physics are different enough that the LHC didn't make a black hole'

Re:Black Hole Calculation (Score:5, Insightful)
Whether something is a black hole or not is not determined by mass but by density. In theory, if you can sqeeze the mass into a small enough volume it will collapse into a black hole. No one ever said that any produced black hole will destroy the solar system, let alone impact the galaxy.
The worst case senario is the blackhole spirals through the Earths crust for the next few hundred thousand years, hardly ever absorbing any matter because of its extremely small size. Even if it were to eventually absorb all the matter of the Earth you would have a black hold smaller than the head of a pin, going around the exact same orbit with the exact same amount of gravitational attraction that the earth had.
Of course, this ignores the fact that such a small black hole will almost instantaniously evaporate in a puff of Hawking radiation. It also ignores the fact that most likely the LHC is an order of magnitude too weak to produce the micro black holes at all. Finally, it ignores the fact that neutron stars exist. If the LHC is powerful enough to produce a stable black hole, then cosmic rays hitting neutron stars are too. After a few million years we wouldn't have neutron stars as they would all be converted to black holes.
The point is, there are lots of reasons that the LHC won't destroy the Earth. Not having enough mass to produce a black hole isn't one of them.
