Long delay to fix collider
Experts have gone into the 27km circular tunnel housing the Large Hadron Collider under the Swiss-French border to examine the damage that halted operations about 36 hours after its September 10 start-up, said James Gillies, spokesman for CERN, the European Organisation for Nuclear Research.
“It’s too early to say precisely what happened, but it seems to be a faulty electrical connection between two magnets that stopped superconducting, melted and led to a mechanical failure and let the helium out,” said Gillies.
