LHC delivers collisions at record energy

After a three-month winter maintenance stop, the Large Hadron Collider [LHC] at CERN has resumed operation, with beams, on 14 March. Two days later, low intensity beams were accelerated to 4 TeV for the first time, achieving a new world record.

During the preceding month, all machine components – including almost 2,000 superconducting magnet circuits – were tested for operation at currents which allow these accelerating beams of up to 4 TeV…
