LHC schedule change

The world's highest energy atom smasher, the Large Hadron Collider (LHC), will run at half its maximum energy through 2011 and likely not at all in 2012. Officials at the European particle physics laboratory, CERN, had previously planned to run the gargantuan accelerator at 70% of maximum energy this year.

The change raises hopes at the LHC's lower-energy rival, the Tevatron Collider at Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, of being extended through 2012 instead of being shut down next year.
