Beams of protons are again circulating around the collider’s 27-kilometre ring, marking the end of a multiple-year hiatus for upgrade work

Data-taking has started again at the LHC: the experiments are continuing their exploration of physics at the unprecedented energy of 13 TeV.

For the first time this year, the LHC is circulating beams of protons, following a 17-week-long extended technical stop

The LHC went into standby on Friday last week following an electrical perturbation at point 8, caused by a small animal

The first low-intensity stable beams have been declared in the LHC following the restart in March 2016

Quiet beams declared in the LHC as the first test collisions are made

On 3 June, experiments at the LHC are set to collect their first physics data in two years, marking the start of the accelerator's second run

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

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

The short circuit to ground delaying the restart of the LHC has been fixed
