During a 2-year technical stop the machine has been prepared for running at almost double the energy of the LHC’s first run. On 9 December 2014, the magnets of one sector of the LHC were successfully powered to the level needed for beams to reach 6.5 TeV. The goal for 2015 will be proton collisions at double the energy.
“After the huge amount of work done over the last two years, the LHC is almost like a new machine,” said CERN’s Director for Accelerators and Technology Frédérick Bordry. ALICE, ATLAS, CMS and LHCb, the four large experiments of the LHC, are also undergoing major preparatory work for run 2. They will now enter their final commissioning phase.
