Description
Resistive Plate Chambers are gaseous detectors extensively used in several domains of Physics given their excellent time and space resolution.
When operated in avalanche mode they make use of a high-performance high- Global Warming Potential gas mixture based on C2H2F4 and SF6, both fluorinated greenhouse components.
The RPC ECOGas@GIF++ Collaboration is carrying on an intense R&D activity devoted to search for new eco-friendly gas mixtures for RPCs, complying with recent European regulations, and assessing their performance in different irradiation conditions on a long-term time scale.
Different Resistive Plate Chambers, flushed with a HFO 1234ze-CO2 based gas mixture, have been exposed to high particle rates at the CERN Gamma Irradiation Facility (GIF++). During a 3 years-long ageing campaign, they have integrated O(100 mC/cm2) and their performance has been systematically evaluated, on a wide range of particle rates, by dedicated beam tests to study possible effects of ageing.
In this talk, results on these studies together with their future perspectives will be presented.
