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
Against a backdrop of great progress in the powering tests for running at 6.5 TeV, a short cicuit is causing a delay, writes Rolf Heuer
