All experiments broke records in the final full operating year of the third run of the LHC

With only three weeks left until CERN’s annual closure, the end of the 2025 run is approaching fast. In less than two weeks, all the beams throughout the accelerator complex will be stopped

Since its first experiment in 2015, the HIE-ISOLDE accelerator has been pushing back the boundaries of nuclear physics

A team of accelerator scientists is testing the use of new, more resistant sensors based on hollow glass fibres to measure particle beams

The 2025 LHC proton run has come to a close, with record performance delivered to all experiments. The LHC now gears up for the upcoming lead-ion run

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

On 6 October, the total integrated luminosity passed the symbolic mark of 100 fb⁻¹, exceeding the forecast curve. This allowed the bunch intensity to be increased to explore the intensity reach and limitations in view of the HL-LHC era

Oliver Brüning, who has led the HL-LHC project since 2020, is handing the position of HL-LHC project leader over to Markus Zerlauth

The delivery of two huge compressors kicks off the installation of the new helium refrigerators for the High-Luminosity LHC
