Large Hadron Collider will restart at half-power
August 7, 2009
The Large Hadron Collider will run at only half its maximum energy when it restarts in November after a serious fault forced it to be shut down for more than a year.
Officials from the CERN particle physics laboratory in Geneva announced last night that it will be 2011 before the world’s most powerful atom-smasher reaches its full capacity.
While the £4 billion “big bang machine” should eventually be capable of running at an energy of 7 teraelectronvolts (TeV), it will operate initially at just 3.5 TeV when it starts smashing protons together in mid-November. The first science results are expected a few weeks later.
It will move up to higher energies only once engineers are confident that it is safe to do so, and it will reach maximum power only after it is shut down for a refit in the winter of 2010-11.
