Geneva, Switzerland (GenevaLunch) – The Large Hadron Collider (LHC) at Cern (European Centre for Nuclear Research) will be switched on this weekend 21-22 November after its year-long repairs. The LHC, the world’s most expensive machine, smashes atoms into each other at very high energies in order to recreate the conditions at the very beginning of the universe. The LHC will start up very slowly at first, probably at no more than 45o GeV, says James Gillies, head of communications. Energy levels will slowly be increased to about 3.5 TeV by mid-January.
GenevaLunch asked Gillies why the LHC, designed to run at 7 TeV, was going to go at only half-steam. He explained that the LHC’s breakdown in September 2008 required a series of careful checks on the machine before it could ramp up to full power.
