The LHC has restarted and both beams have been circulating in the machine since 8 April, meaning that the start of the LHC beam commissioning during Easter is apparently not a constant of nature

The first beam-based physics of 2025 has started and more will follow soon. However, some unexpected challenges will cause a small delay in the restart of the LHC

The recommissioning of the accelerators is progressing according to schedule. Unsurprisingly, some issues have arisen, but they have been swiftly addressed by equipment experts. First physics in the PS East Area and n_TOF is scheduled to start next week

While the first H⁻ ion beams have been accelerated up to 160 MeV in Linac4, the PS Booster is preparing for its first proton injection of 2025

The activities of the year-end technical stop (YETS) have come to an end in the first machines of the injector complex

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

Soon, CERN personnel will take a well-deserved winter break, just like the accelerator complex. Following a successful year, the remainder of the accelerator complex was stopped on 2 December, marking the official start of the year-end technical stop

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

Lead-ion physics at the LHC and the SPS North Area is already under way and progressing well. The final lead-ion user in the PS East Area started its physics run on 13 November

As the LHC and SPS wrap up their 2024 proton run, teams are making final preparations for the lead-ion physics run starting on 4 November

This year’s LHC proton run ended on 16 October, surpassing expectations with 11% more collisions than planned. Next up: the lead-ion run
