Description
Run 3 data taking of the LHC will conclude in the summer of 2026. So far, the CMS experiment has accumulated 30.36 fb⁻¹ of proton-proton collision data at a center-of-mass energy of 13.6 TeV in 2026 alone, bringing the total for the entire Run 3 to 326.03 fb⁻¹. The CMS experiment is designed to identify muons robustly, efficiently and redundantly. One of the detectors used for this purpose is part of the muon system and consists of resistive plate chambers (RPC). These detectors are present in both the barrel and endcap regions. The RPCs undergo calibrations to optimize the operating voltage of each chamber and ensure stable detector performance under varying running conditions. In parallel, several performance and operational studies are carried out to guarantee high data quality and reliable detector operation. The latest RPC performance results will be presented, including the most recent calibrations performed on the detector. These results will cover detector efficiency, cluster size, and operational stability. A summary of the ongoing upgrade activities and their current status will also be presented.
