| Abstract |
| Resistive Plate Chambers (RPCs) are gaseous detectors widely used in high energy physics experiments, such as Compact muon solenoid detector (CMS), operating with a gas mixture primarily containing Tetrafluoroethane (C2H2F4), commonly known as R-134a, which has a global warming potential (GWP) of 1430. In response to climate change concerns and to comply with European regulations, the RPC EcoGas@GIF++ collaboration, involving different experiments, has undertaken intensive research and development efforts to explore new environmentally friendly alternative gas mixtures for RPC technology. Several eco-friendly alternatives to C2H2F4, have been studied in the last few years in order to find an alternative mixture with low GWP, while maintaining reasonable performance of the RPC chambers. An aging test campaign was launched at the CERN Gamma Irradiation Facility and during test beams the detector performance has been studied with different gas mixtures under the conditions of High luminosity LHC Phase. This talk will report the latest results of the aging studies and the performance evaluations of the detector. |
