“…In order to draw consistent test results, applied high-voltage (HV app ) values were converted to effective values (HV eff ) under the standard conditions, P = 1013 hPa and T = 293 K [8]. The prototype multigap RPCs were installed at a mean distance of 45 cm from a 200-mCi 137 Cs gamma source to examine detector responses to high-rate gamma-ray background.…”

We report a systematic study of phenolic multigap Resistive Plate Chambers (RPCs) for highrate triggers in CMS. In the current R&D, prototype RPC modules have been built with fourand six-gap structures and tested with cosmic muons and gamma rays irradiated from a 200-mCi 137 Cs source. The detector characteristics of the prototype multigap RPCs were compared with those of the double-gap RPCs currently used in the CMS experiment at LHC. The mean values for detector charges of the cosmic-muon signals drawn in the four-and six-gap RPCs for the efficiency values in the middle of the plateau were about 1.5 and 0.9 pC, respectively. We concluded from the current R&D that use of the phenolic multigap RPCs is advantageous to future high-rate triggers in CMS in virtue of the smaller detector pulses.

“…Taking into account an additional safety factor, a rate capability of around 2 kHz/cm 2 should be required for the new chambers, while standard CMS double-gap RPCs have been tested to reach around 1 kHz/cm 2 (see, for instance, [9]). Therefore an improvement in the rate capability of these detectors is needed.…”

The CMS muon system is based on three types of gaseous detectors, RPC, CSC and DT. While operating very well in the present conditions, upgrades are foreseen for each of the subsystems, necessary to cope with the increased pile-up, coming along with higher rates and radiation, during the upcoming periods of data taking.Moreover, an important issue will be to make the system able to perform its delicate task of muon triggering and tracking also in the High Luminosity phase of LHC, foreseen to start after Long Shutdown 3 in 2023 and to last for about 10 years.Studies devoted to asses the system perfomance stability for the future will be presented. In addition, the stategy -which is being developed -to complement the existing system with new detectors, based on GEM or improved RPC technologies, will be shown.

The Resistive Plate Chambers (RPC) detector of the CMS experiment at the LHC proton collider (CERN, Switzerland) will employ an online gas analysis and monitoring system of the freon-based gas mixture used. We give an overview of the CMS RPC gas system, describe the project parameters and first results on gas-chromatograph analysis. Finally, we report on preliminary results for a set of monitor RPC.
