Abstract :
Several small single gap Resistive Plate Chambers and two RB1 CMS final stations have been exposed during the last year at the CERN Gamma Irradiation Facility to study possible long-term ageing effects. Up to now, an integrated charge of about 0.05 C / ( cm 2 gap ) and 0.025 C/(cm 2 gap) has been accumulated for the small RPCs and the large RB1 stations, respectively. Current, rate, fast charge and efficiency have been continuously monitored with muon beam or cosmics. Results concerning operation with a moisty mixture are also reported.
