Performance of multigap resistive plate chamber in a γ-ray aging test 1 first-author 1 1 1 1 1 Department of Modern Physics, University of Science & Technology of China, Hefei 230026, China Department of Modern Physics, University of Science & Technology of China, Hefei 230026, China The aging test of multigap resistive chamber (MRPC) was carried out under conditions of irradiation from a 137 Cs γ source facility. The total charge induced at the anode or at the cathode of the MRPC module was about 29 mC. The gamma dose rate was 10 -2 Gy·h -1 , and the total accumulative radiation dose was 4.3 Gy. After irradiation, there was an obvious degradation in the properties of the MRPC module. MRPC Irradiation dose Aging References Williams M.C.S ., Nucl. Instr. Meth . 2002 , A 478 : 183 . Nucl.
