    Abstract

    We present recent results of an extensive aging test, performed at the CERN Gamma Irradiation Facility, on two bakelite Resistive Plate Chambers (RPC) detectors. With a method based on a model describing the behavior of an RPC exposed to a large particle flux, we have periodically measured the electrode resistivity ρ of the two detectors over 3 years. We observed a large increase of ρ with time, from initial values of about 1010 Ω cm to more than 200 × 1010 Ω cm. A corresponding degradation of the RPC rate capability, from about 3 kHz/cm2 to less than 200 Hz/cm2, was observed. The reversibility of the process, using a humid gas mixture, has also been studied.
