The effect of temperature on the rate capability of glass timing RPCs

In this study, we demonstrate a strong influence of the working temperature on the counting rate capability of large-area timing resistive plate chambers (RPCs) incorporating industrial flat glass electrodes. The effect relies on the sharp dependence of glass resistivity on temperature, approximately one order of magnitude for each 25 °C, allowing a considerable extension of the counting rate capability merely by a moderate warming of the detector. sults confirm operation at 1.5 kHz/cm2 for irradiation with gamma photons, and may be extrapolated to 6 kHz/cm2 for the detection of minimum ionizing particles (MIPs) with a timing resolution below 100 ps σ.
