The LHC starts again after a short technical stop

28 February 2010

After a short technical stop, beams circulate again on 28 February 2010. A month later, on 19 March, 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.
