Results obtained by the RPC ECOgas@GIF++ Collaboration, using Resistive Plate
Chambers operated with new, eco-friendly gas mixtures, based on
Tetrafluoropropene and carbon dioxide, are shown and discussed in this paper.
Tests aimed to assess the performance of this kind of detectors in
high-irradiation conditions, analogous to the ones foreseen for the coming
years at the Large Hadron Collider experiments, were performed, and demonstrate
a performance basically similar to the one obtained with the gas mixtures
currently in use, based on Tetrafluoroethane, which is being progressively
phased out for its possible contribution to the greenhouse effect. Long term
aging tests are also being carried out, with the goal to demonstrate the
possibility of using these eco-friendly gas mixtures during the whole High
Luminosity phase of the Large Hadron Collider.Comment: Submitted to European Physical Journal C on October 24, 2023, 15
