LHC breaks energy record

The Large Hadron Collider has beaten its own world record for accelerating particles. Around midnight last night, engineers at CERN broke a world record when they accelerated a beam of particles to 6.5 trillion electronvolts—60 percent higher than the previous world record of 4 TeV. On April 5 engineers sent beams of protons all the way around the improved Large Hadron Collider for the first time in more than two years (pictured above). On April 9, they ramped up the power of the LHC and maint...
