We will make the repair and resume the very successful operation of the accelerator."Ī transformer failed outside the cold zone about 36 hours after the collider's launch. "We have encountered a weakness in one particular connection during very final hardware commissioning," Engelen told The Associated Press by e-mail. Jos Engelen, CERN's chief scientific officer and deputy director-general, said the startup showed that the LHC can handle complex operations. Then proton beams were fired in the counterclockwise tube. 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. "Once they settled in they seem to be pretty stable," Gillies said.Īt the Sept. 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. 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. There has been some discussion that the new equipment could operate through the winter, but no decision has been made, he said. "It's obviously a short-term disappointment, though, and a lost opportunity," he wrote.ĬERN spokesman James Gillies said the repair operation will last until close to the usual winter shutdown time at the end of November. physicists working at the European Organization for Nuclear Research, or CERN. "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. That means Friday's meltdown could end up putting off high-energy collisions of particles - the machine's ultimate objective - until 2009. Then it has to be re-chilled for another month.Īs a result, the equipment may not be running again before the planned shutdown of the equipment for the winter to reduce electricity costs. Send us feedback.GENEVA - Scientists expect startup glitches in the massive, complex machines they use to smash atoms.īut 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.īecause 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.

Recent Examples on the Web The new circular supercollider will sit next to its predecessor at CERN in Switzerland, but will be nearly three times its size, with a circumference of 100 kilometers.Īndrea Willige, Forbes, 18 Mar. ![]()
