And they’re off! The 2025 LHC physics season gets underway
“Stable” particle beams are back in the LHC machine, marking the start of the 2025 physics data-taking campaign
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*).
The 2025 campaign will start with proton collisions at 13.6 TeV, and the proposed integrated luminosity targets for the LHC’s four experiments are ambitious, aiming for almost as much as in 2024, although the proton-proton programme will be shorter than last year. And the more luminosity, July.
the more collisions for the experiments and therefore more data. The lead ion campaign will take place in October and November, and the lessons learned from the 2024 campaign could lead to further optimisation, and therefore greater integrated luminosity. New in 2025: the LHC’s first oxygen ion run will take place in
