Two cold boxes have been transported down into the service tunnels of the future accelerator

The CMS Collaboration demonstrates that machine learning can outperform traditional methods in the full reconstruction of particle collisions at the LHC

CMS has recently completed the first prototype slice of its innovative High-Granularity Calorimeter (HGCAL), which will be the largest silicon-based detector ever built

As we prepare to implement the High-Luminosity LHC and secure approval of a flagship collider to follow it, we must work together to create the best possible environment for success

This technical stop is particularly intense, being both shorter than usual, to maximise the limited time for physics, and very busy, to make essential preparations for LS3, which begins in June

A look back at a year of advances in science, technology and benefits to society

The first large refrigerators for the High-Luminosity LHC have been installed

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

The software managing CERN’s compute workload has handled a massive stress test, far beyond normal operating conditions, designed to simulate the needs of the future

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

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
