Description
This poster presents the efforts to boost the performance and the reliability of the Resistive Plate Chambers (RPC) of the muon system of the Compact Muon Solenoid (CMS) experiment. The focus is on both the maintenance of the existing RPC chambers and the installation of the improved RPC detectors (iRPC) for the Phase-II upgrade. The RPC system consolidation is based on the standard maintenance of the present power system and the gas leak repair, which would allow powering back on the leaking chambers. The installation of 72 new improved RPC detectors, in addition to the upgrade of the power system, is ongoing as part of the new RPC Phase-II upgrade programme. At the end of 2024, 36 iRPC chambers were installed and are already under commissioning in the CMS experiment. This poster offers valuable insights into the maintenance procedures of the RPC detector and the activities crucial for the success of the ongoing and Phase-II data taking of CMS.
