Performance of improved RPCs demonstrator for the CMS at the HL-LHC

Pressure correction study for the CMS iRPC detector

“…Due to the small thickness of the gas gap, the number of electrons generated by the passage of charged particles through the gap will be reduced and absorbed faster in the thinner electrodes which increases the sensitivity and rate capability of the detector. A sensitive, low-noise, high-time resolution Front-End Electronics Board (FEB v2.2) [2] is used to handle low charge signals with a threshold below 50 fC and keep the iRPC efficiency as high as in the usual RPC [3].…”
