Aging Study on Resistive Plate Chambers of the CMS muon detector for HL-LHC (Reham Aly)

Presented on General Muon Meeting (GMM) on 27 January 2020. Slides


The RPC system has been certified for 10 years of LHC (at nominal luminosity of 1034 cm-2s-1 1034 cm-2s-1 ). Longevity program aims to certify that the present RPC detectors can survive the hard background conditions during the HL-LHC period. A dedicated longevity test is set up at the CERN Gamma Irradiation Facility (GIF++), since July 2016 where few spare RPCs are exposed to a high gamma radiation for a long term period to mimic the HL-LHC operational conditions. Two chambers are continuously irradiated “IRR. chambers” and two chambers are turn on from time to time and used as a reference “Ref. chambers” During the longevity test the main detector parameters are monitored as a function of the collected integrated charge. The plots are an update for approved plots in this link And talks
