First collisions at LHC at 7 TEV! The two beams are at 3.5 TEV each and everything is cool!
CERN has a live webcast here ((Please note that, as of the date of republishing this archived post, the webcast is no longer available. In lieu, here are some clips from the day: The high-energy collisions at 7 TeV, building 40, 30th March 2010, LHC News April 2010 : LHC First Physics, LHC first physics : clip resume of the day March the 30th, 2010)).
