RPC EcoGas@GIF++ Collaboration

Description

Gaseous detectors play a crucial role in high energy physics experiments, yet their operation often relies on fluorinated gases with a very high Global Warming Potential (GWP). Resistive Plate Chambers (RPCs) operated in avalanche mode typically use high performance gas mixtures based on high-GWP F-gases such as C₂H₂F₄ and SF₆.
As environmental concerns grow and regulations become increasingly stringent, the development of sustainable gas mixtures has become a global priority.

Within the RPC ECOGas@GIF++ Collaboration, a long term R&D program has investigated eco friendly gas mixtures for RPCs and assessed their performance under irradiation. RPCs operated with an HFO-1234ze/CO₂ mixture were exposed to high particle fluxes at CERN GIF++, accumulating O(10² mC/cm²) over three years. This ageing campaign is now complete, and the detectors’ performance has been systematically evaluated across a broad range of rates.

This talk will present preliminary final results from the campaign, along with future perspectives.
