Second chance for Large Hadron Collider to deliver universe's secrets

At first glance, the piece of metal in Steve Myers’s hands could be taken for a harmonica or a pen. Only on closer inspection can you make out its true nature. Myers, director of accelerators at the Cern particle physics laboratory outside Geneva, is clutching a section of copper piping from which a flat electrical cable is protruding.

It looks unremarkable. Yet a piece of cable like this one was responsible last year for the world’s most expensive short-circuit. More than £30m-worth of damage was done to the Large Hadron Collider (LHC), the most advanced particle accelerator ever built, a few days after its ceremonial opening. It has taken Myers – and hundreds of other Cern scientists – more than a year to pinpoint the guilty piece of cable and repair the wreckage. “It was a very small piece, but it did immense damage,” he said. It remains to be seen whether Myers can fix Cern’s tattered technological reputation in the process – when his team restart their great machine in a few weeks. “I am not a nervous person,” said the 63-year-old Belfast-born engineer. “And that is probably just as well.” more

Science correspondent Ian Sample talks to Lynn Evans, project manager of Cern’s Large Hadron Collider, who relives the moment he found out something had gone horribly wrong:
