The proton physics run has now been paused for the first block of machine development studies, a technical stop and short oxygen- and neon-ion physics runs. Protons will be back in the machines on 12 July

Following the achievement of 2460-bunch stable beams on 24 May, the accelerator complex experienced an SPS magnet failure, a central timing glitch and a complex-wide power disruption. Yet the LHC remains on track to achieve its 2025 luminosity goal

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

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 tenth year of operation ends with exceptional data collection

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

On 23 September, the LHC reached its 2024 target for integrated luminosity. And then a cryogenic station broke down…

The physics run for the SPS North Area will start on 4 November, followed by the LHC lead-ion physics run on 6 November, and the PS East Area on 11 November

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

CERN’s accelerators show very good availability rates: beams are in place

Restarting the entire accelerator complex after a technical stop is rarely seamless and often comes with unexpected technical challenges

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