Performances of Resistive Plate chamber Operated in Avalanche Mode under 137Cs Irradiation

A 2 mm gas RPC with bakelite plates has been operated in avalanche mode under 137Cs source irradiation. We report on measurements of the efficiency in cosmic rays detection and of the charge developed in the gap, performed for different gas mixtures. We show that C2H2F4 based mixtures exhibit a wide...

Sumario:A 2 mm gas RPC with bakelite plates has been operated in avalanche mode under 137Cs source irradiation. We report on measurements of the efficiency in cosmic rays detection and of the charge developed in the gap, performed for different gas mixtures. We show that C2H2F4 based mixtures exhibit a wide full efficiency plateau with low streamer probability, while the argon based mixtures allow to reduce the detector power consumption
