Description
"Gas systems for Particle Detectors"
Over the five experiments (ALICE, ATLAS, CMS, LHCb and TOTEM) taking data at the CERN Large Hadron Collider (LHC) 30 gas systems are delivering the proper gas mixture to the corresponding detectors. They are complex apparatus that extend over several hundred of meters and have to ensure extremely high reliability in terms of stability and gas mixture quality. In fact, the gas mixture is the detector sensitive medium: correct and stable composition are basic requirements for good and safe long-term detector operation.
The operational experience during the LHC Run 1 demonstrated an impressive reliability level, greater than 99.95%, corresponding to less than 1.5 hours of downtime per year. An intensive maintenance and upgrade program is on-going in order to consolidate these performance for future operation.
In this seminar the PH-DT gas systems design philosophy and the recent developments focusing the attention on the main functional modules will be discussed.
