Over the five experiments (ALICE, ATLAS, CMS, LHCb and TOTEM) taking data at the CERN Large Hadron Collider (LHC) more than 28 gas systems are delivering the proper gas mixture to the corresponding detectors. They are complex systems that extend over several hundred meters and have to ensure an extremely high reliability in terms of stability and quality of the gas mixture delivered to the detectors...
The Compact Muon Solenoid (CMS) experiment at the CERN Large Hadron Collider (LHC) is equipped with four gas systems, one per each of the muon detectors (i.e. Cathode Strip Chambers, Drift Tube and Resistive Plate Chambers) and one for the inner detectors neutral gas flushing (pixel, tracker, Electromagnetic and Hadron calorimeters). Each gas detector is suitable operated with a well defined gas mixture...
