Performance of RPC with low-resistive silicate glass electrodes exposed to an intense continuous electron beam

摘要

Four-gap resistive plate chamber (RPC) prototypes with silicate glass electrodes (bulk resistivity ～10~8-10~9 Ω cm) were studied for suitability in time-of-flight (TOF) applications at high rates. These studies were performed using a continuous electron beam of 34MeV at the FZ Dresden-Rossendorf electron linac ELBE. Time resolutions of about 100 ps and efficiencies larger than 95% were obtained for flux densities up to 20 kHz/cm~2.
