The 2025 run was successfully completed on 8 December at 6.00 a.m., signalling the start of the year-end technical stop for the LHC and the injector complex

With only three weeks left until CERN’s annual closure, the end of the 2025 run is approaching fast. In less than two weeks, all the beams throughout the accelerator complex will be stopped

The 2025 LHC proton run has come to a close, with record performance delivered to all experiments. The LHC now gears up for the upcoming lead-ion run

“Stable" particle beams are back in the LHC machine, marking the start of the 2025 physics data-taking campaign

The Chamonix Workshop is in full swing, and the initial outlines of the 2025 LHC configuration and operational scenarios are beginning to take shape

Although the much-appreciated winter break is well behind us and most of us are back at work, the accelerator complex is still in hibernation – but not for much longer

The LHC was scheduled to conclude its outstanding 2024 run on 25 November, but a massive magnet quench brought it to an end two days early

The LHC's third run has been extended until July 2026. The long technical stop that will follow will be extended by four months, postponing the start-up of the High-Luminosity LHC until June 2030

On Sunday, 1 September, the LHC integrated luminosity for Run 3 (2022–2025) equalled that of Run 2 (2015–2018)

The ATLAS collaboration has released its first results from searches for new physics phenomena conducted with data from Run 3 of the LHC

Dismantling a beam dump is a real conundrum – that’s what the 2020 “autopsy” concluded. To solve it, the new spare LHC beam dumps have been made easier to “cut”

We are optimistic that we will have a successful luminosity production period this summer
