CERN’s next accelerator, the High-Luminosity LHC (HL-LHC), aims to crank up the current collider’s performance by increasing the integrated luminosity tenfold beyond the design value of the LHC. We are fast-approaching Long Shutdown 3, when the accelerator will be shut off for 47 months from July 2026, and during which all installations for the HL-LHC will be completed – ready for the start of the HL-LHC era in June 2030. 

This is now, therefore, a critical time for the project as all teams, both within CERN and in the numerous collaborating instututes worldwide, work towards the shutdown period.  

The annual project newsletter, including contrubutions from across the project, contains updates and progress from the evolution of collaborations, testing, and integration activities to specific technologies like the magnets, crab cavities and beam instrumentation.
