After initial lower energy collision physics from November 2009 onwards, ATLAS records collisions at 7 TeV centre-of-mass energy for the first time. Particle physicists around the world anticipate a rich harvest of new physics as the LHC begins its first long run at an energy three and a half times higher than previously achieved at a particle accelerator.
