The TBPS Rings are in production, offering an innovative design to incline sensors toward the LHC beam and maximise coverage. They are the first support structures in production for the new Tracker!
The first of the improved Resistive Plate Chambers for Hi-Lumi CMS were installed in record time during the LHC winter break.
CERN and CMS engineers and technicians have installed the first two of nine required next-generation carbon dioxide (CO2) cooling plants in the underground Service Cavern of the CMS experiment in Cessy, France, as well as two of the accumulators.
2024 was an impressive year: the most data ever collected by CMS, many important results including two landmark results (

CMS scientists discover some of the rarest collisions that the LHC can produce – such as the scattering of light by light – and learn more about the quantum nature of electromagnetism, search for new particles, and much more.
Welcome to our look back at 2024 - and what a year it has been!
The heavy ion Run has just concluded, marking the start of the extended year-end technical stop (EYETS). Reflecting on 2024, this year’s LHC Run exceeded expectations, delivering the highest accumulated data volume to date.
