Another year of outstanding accelerator complex performance
By Mike Lamont Another fantastic year of LHC proton–proton operation came to an end on 18 November, with 125 fb⁻¹ delivered to both ATLAS and CMS, 12.5 fb⁻¹ to LHCb and a smidgeon to ALICE in line with their more modest proton demands. All this follows the similarly spectacular performance of 2024. Over the full…

Accelerator Report: A summer of hot spells for the LHC
So far the summer run has seen solid progress in luminosity production, but also some unexpected beam and machine behaviour. Careful monitoring revealed a hardware issue, now being closely watched as the LHC continues to perform at full capacity.

Accelerator Report: Focus on luminosity production
Following the successful oxygen and neon ion runs, protons are back in the LHC, delivering luminosity at a high rate and slowly catching up with the forecast production rate. In addition, a slight increase of the bunch intensity is being considered

Accelerator Report: The LHC wraps up its first 2025 physics block
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

Accelerator Report: LHC on track despite disruptions throughout the accelerator complex
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

Accelerator Report: The LHC reached 1200 bunches per beam – full intensity is in sight!
On 19 May, the LHC reached 1200 bunches per beam, a level that is considered meaningful for physics. The full intensity of 2460 bunches per beam could be achieved before the end of the week.

Accelerator Report: The first stable beams of 2025, a milestone and a beginning
The LHC operations team and many other experts have been working hard to set up and validate the accelerator for safe beam operation, leading to the first stable beams for physics of 2025 on 5 May

And they’re off! The 2025 LHC physics season gets underway
Today at 13h51, the engineer in charge of the LHC at the CERN Control Centre announced that stable beams had returned to the Large Hadron Collider (LHC), marking the start of the 2025 physics data-taking campaign, the fourth year of the LHC’s third operating period (Run 3*).
