Particle accelerator to restart in September

GENEVA (AP)  — Additional safety features being added to the world's largest particle accelerator will postpone its startup until the end of September, a year after the $10 billion machine was sidelined by an electrical fault, the operator said Tuesday. The cost of the repairs and added safety features has yet to be determined, but it will be covered by the regular budget of the European Organization for Nuclear Research, spokeswoman Christine Sutton said. Scientists have taken the setback in stride, saying that particle colliders always have such problems in the startup phase.
