Effect of temperature on MRPC with pad read-outs

To obtain a quantitative understanding of the influence of temperature on the performance of multi-gap resistive plate chambers (MRPCs), we have tested the performance of a 10-gap, 12-pad, 2×2×12 cm² active area MRPC at different temperatures with cosmic rays. Presented are results from measurements of high-voltage scans, noise rate, dark current, streamer, time resolution, count rate, charge spectrum, and detection efficiency. The test results show that the MRPC performance is significantly affected by temperature arising from the temperature-dependence of the glass resistivity.
