I usually use a lighter, but this explains the basic physics behind it.

More glitches for the Large Hadron Collider (LHC): The same day operators announced that a 30-ton transformer that cools part of the particle smasher had broken within hours of the LHC’s launch last week, a mishap yesterday resulted in “a large helium leak” into the collider’s tunnel.

According to a press statement, “the most likely cause of the problem was a faulty electrical connection between two magnets, which probably melted at high current leading to mechanical failure.”

Scientists expect startup glitches in the massive, complex machines they use to smash atoms.

But the unique qualities of the world’s largest particle collider mean that the meltdown of a small electrical connection could delay its groundbreaking research until next year, scientists said Sunday.

Because the Large Hadron Collider operates at near absolute zero — colder than outer space — the damaged area must be warmed to a temperature where humans can work. That takes about a month. Then it has to be re-chilled for another month.

As a result, the equipment may not be running again before the planned shutdown of the equipment for the winter to reduce electricity costs. That means Friday’s meltdown could end up putting off high-energy collisions of particles — the machine’s ultimate objective — until 2009.

“Hopefully we’ll come online and go quickly to full energy a few months into 2009 so in the long term, this may not end up being such a large delay in the physics program,” Seth Zenz, a graduate student from the University of California, wrote on the site of the U.S. physicists working at the European Organization for Nuclear Research, or CERN.

“It’s obviously a short-term disappointment, though, and a lost opportunity,” he wrote.

CERN spokesman James Gillies said the repair operation will last until close to the usual winter shutdown time at the end of November. There has been some discussion that the new equipment could operate through the winter, but no decision has been made, he said.

The melting of the wire connecting two magnets Friday would have taken only a couple of days to repair on smaller, room-temperature accelerators that have been in use for decades, Gillies said.

Gillies said particle accelerators using superconducting equipment at Fermilab outside Chicago and at Brookhaven National Laboratory in New York state had similar problems starting up, but have been operating smoothly since then.

“Once they settled in they seem to be pretty stable,” Gillies said.

At the Sept. 10 launch of the collider, beams of protons from the nuclei of atoms were fired first at the speed of light in a clockwise direction though a fire-hose-sized tube in the tunnel. Then proton beams were fired in the counterclockwise tube.

Dear Sebastian,

How they laughed at us at school. How they called us geeks and squares and laughed at our haircuts and glasses. How they ridiculed us because we could do the Rubik’s cube and name all the dinosaurs.

Oh, remember how the girls mocked our shitty shoes? Our clothes? Accused us of stalking? Well my friend the time is near. First week of October…boom!!!

Hahahaha, hehehehe, hahahahahah!”
