We present recent results of an extensive aging test, performed at the CERN Gamma Irradiation Facility on two single-gap RPC prototypes, developed for the LHCb Muon System. With a method based on a model describing the behaviour of an RPC under high particle flux conditions, we have periodically measured the electrode resistance R of the two RPC prototypes over three years: we observe a large spontaneous increase of R with time, from the initial value of about 2 MOmega to more than 250 MOmega. A corresponding degradation of the RPC rate capabilities, from more than 3 kHz/cm(2) to less than 0.15 kHz/cm(2) is also found.

Abstract
We present recent results of an extensive aging test, performed at the CERN Gamma Irradiation Facility on two single-gap RPC prototypes, developed for the LHCb Muon System. With a method based on a model describing the behaviour of an RPC under high particle flux conditions, we have periodically measured the electrode resistance R of the two RPC prototypes over three years: we observe a large spontaneous increase of R with time, from the initial value of about 2 MOmega to more than 250 MOmega. A corresponding degradation of the RPC rate capabilities, from more than 3 kHz/cm(2) to less than 0.15 kHz/cm(2) is also found.File in questo prodotto:
