The two beams circulating in the LHC are currently running with different bunch intensities – an unexpected (but successful) premiere, giving us a good chance to reach last year’s luminosity record

The accelerators that feed into the Large Hadron Collider are ready to supply more intense beams

Klystrons are key components in the development of future energy-efficient colliders. The latest edition of the CERN Courier magazine explores their recent developments.

The four accelerators that feed into the Large Hadron Collider have all been restarted, while the LHC itself will receive its first particles in April

Reviewing accelerator operations, supporting an increasingly diverse physics programme and preparing for the High-Luminosity LHC and beyond were key themes of this year’s Chamonix Workshop

Soon, CERN personnel will take a well-deserved winter break, just like the accelerator complex. Following a successful year, the remainder of the accelerator complex was stopped on 2 December, marking the official start of the year-end technical stop

The LHC's third run has been extended until July 2026. The long technical stop that will follow will be extended by four months, postponing the start-up of the High-Luminosity LHC until June 2030
