CERN Accelerating science

The extraordinary performance reflects decades of accumulated expertise, a culture of continuous development and improvement, and a sustained collective effort across all technical and operational domains

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

At a dedicated meeting of the CERN Council on 6-7 November, delegates from CERN’s Member and Associate Member States reviewed the outcome of the Feasibility Study for the proposed Future Circular Collider

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
