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.
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
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
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
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
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
