Description
The RPC detectors in the CMS experiment operate with a gas mixture made of 95.2% C2H2F4, known to be a greenhouse gas. Several eco-friendly alternatives to C2H2F4, such as HFO, have been studied in the last few years in order to find an alternative mixture with low Global-Warming Potential (GWP), while maintaining the performance of the RPC chambers. Another way to improve the RPC standard gas mixture GWP, could be replacing between 30% and 40% of the C2H2F4 with CO2. Studies of Eco-gas and CO2 based mixtures are carried out at the CERN Gamma Irradiation Facility (GIF++), where the LHC Phase-2 conditions are mimicked by a 13.6TBq radiation source and a muon beam. This poster presents the performance of a 1.4 mm gap RPC chamber with several alternative gas mixtures in a high gamma background environment, as well as future perspectives of aging studies.
