Description
In the future Phase-2 LHC runs, LHC instantaneous luminosity will reach a maximum value of 7×10^34 cm^-2 s^-1 and the CMS muon system will be extended up to η (pseudo rapidity) region of 2.4 where the expected maximum particle rate is 600 Hz cm^-2. In view of the expected background conditions, we have studied high-sensitive thin phenolics double-gap RPC models to improve the rate capability in the past few years. The improved Resistive Plate Chambers (iRPCs) has been studied with cosmic muons and with 100-GeV SPS H4 muon beams at CERN at the new Gamma Irradiation Facility (GIF++). The performance of iRPC was tested with a maximum gamma rate of about 4 kHz cm^-2 by using dedicated algorithm for clustering and tracking and fairly satisfies the operational condition required in the future Phase-2 LHC.
