Accelerator Report: Preparing for 2025 LHC operation and setting goals

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 year-end technical stop (YETS) activities in the accelerator complex’s first machines are nearing completion, but in the LHC about six weeks of work still lie ahead of us before the machine is handed over to the Operations group on 13 March for recommissioning.

While having a well-defined and approved schedule is essential, an equally critical element for the 2025 run is establishing clear operational configurations and scenarios. These are developed and refined throughout the year in various meetings, working groups and committees. They are then consolidated in two key workshops, which are vital not only to ensure the immediate operation of the accelerator complex but also to prepare its long-term future…
