Description
We studied 200 MeV proton irradiation effects on Hamamatsu MPPCs (Si-PMs) in the Wakasa-wan Energy Research Center in Japan. Hamamatsu K.K. made test versions of MPPCs (S14420-3050MOD, S14160-3050MOD) and we studied these performances. As a result, dark current and lower energy threshold of modified MPPCs were comparable to the old one, and thus there were no significant improvements observed in our experiments.
