Huge $10 billion collider resumes hunt for 'God particle'

The LHC, the world's largest particle accelerator, has been under repair for more than a year because of an electrical failure in September 2008.

Now, excitement and mysticism are building again around the $10 billion machine as the European Organization for Nuclear Research (CERN) gears up to circulate a high-energy proton beam around the collider's 17-mile tunnel. The event should take place this month, said Steve Myers, CERN's Director for Accelerators and Technology.

The collider made headlines last week when a bird apparently dropped a "bit of baguette" into the accelerator, making the machine shut down. The incident was similar in effect to a standard power cut, said spokeswoman Katie Yurkewicz. Had the machine been going, there would have been no damage, but beams would have been stopped until the machine could be cooled back down to operating temperatures, she said.
