The performance of RPCs with bakelite electrodes of resistivity under high radiation fluxes

Three medium-size Resistive Plate Chambers (RPCs) with bakelite electrodes having resistivity of 5*10/sup 8/, 5*10/sup 9/ and 3*10 /sup 10/ Omega cm were tested in the Gamma Irradiation Facility at CERN in 1997, 1998 and 1999. The 2 mm gap modules working in an Inverted Double Gap configuration fill...

Descripción
Sumario:Three medium-size Resistive Plate Chambers (RPCs) with bakelite electrodes having resistivity of 5*10/sup 8/, 5*10/sup 9/ and 3*10 /sup 10/ Omega cm were tested in the Gamma Irradiation Facility at CERN in 1997, 1998 and 1999. The 2 mm gap modules working in an Inverted Double Gap configuration filled with gas mixtures containing freon C/sub 2/H/sub 2/F/sub 4/ and operated in avalanche mode exhibit wide efficiency plateau, good time resolution and small time walk due to rate variation even at intensities as high as 1 kHz/cm/sup 2//gap of a continuous radiation flux.
