The Large Hadron Collider (LHC) will reopen for business in late September and will start conducting experiments a month later, the European particle-physics lab CERN in Geneva, Switzerland, announced today. The LHC, the world's most powerful particle collider, has been closed for repairs since 19 September 2008, when an electrical fault triggered a leak of liquid-helium coolant, damaging 53 of the LHC's superconducting magnets.
