CERN Accelerating science

Watch 11 physicists from the LHC experiments ALICE, ATLAS, CMS and LHCb explain what they hope to discover during the accelerator's second run

This morning, for the first time in two years, proton-proton collisions were delivered to the LHC experiments at injection energy: 450 GeV per beam

After both beams having been ramped to their full energy of 6.5 TeV, the last two weeks saw the beam commissioning process advancing on many fronts

The LHC restart, highlights from FCC week, the first bending magnet of SESAME and more in this spring issue

The major news this week is, of course, the start of LHC Run 2

Last night the LHC operations team successfully circulated a beam at 6.5 TeV - one of many steps before the LHC can deliver collisions to experiments

With proton beams back in the LHC, operations experts have weeks of work to do before they can collide beams in experiments at the energy of 13 TeV

Some 340 people attended the inaugural FCC conference week in Washington DC to discuss the study status and plans for the future

The LHC started up again on Sunday for the first time in two years. LHC operators celebrated the smooth restart with champagne and chocolate eggs

Featuring some 33 talks about latest results and the future of cosmic-ray physics, CERN’s AMS Days will take place from 15-17 April

After two years of intense maintenance and consolidation the Large Hadron Collider is back in operation

The first beams could be circulating in the machine sometime between Saturday and Monday
