The LHC starts again after a short technical stop

After a short technical stop, beams circulate again on 28 February 2010. On 19 March 2010, two 3.5 TeV proton beams successfully circulate in the Large Hadron Collider for the first time. This is the highest energy yet achieved in a particle accelerator and an important step on the way to the start of the LHC research programme.
