Every day counts, so the LHC operations teams have mapped out a precise sequence of running phases to maximise the physics output during the machine’s final months

The final physics season at the LHC has just kicked off! The experiments will record collisions until the end of June, when work will begin on transforming the machine into a high-luminosity accelerator.

Many activities are currently progressing across the accelerator chain as the complex moves steadily towards full operation

Beam commissioning is progressing well in CERN’s accelerator complex, with beams already at the gates of the SPS

Linac4 and the PS Booster have already completed their standalone beam commissioning successfully and have handed over the baton to the PS

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
