Abstract
Resistive Plate Counters (RPC) detectors at the Large Hadron Collider (LHC) experiments nor- mally use gas recirculation systems to cope with large gas mixture volumes and costs. A new long-term systematic study of gas purifiers has been carried out at CERN in a low-radiation test area, with the use of RPC chambers with currents monitoring and gas analysis. The study aims at measuring the lifetime of purifiers, release of contaminants, and to characterize the behavior of RPC dark currents as a function of contaminants.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
