We have developed a multi-pixel photon counter (MPPC) with Hamamatsu Photonics for use in the TokaiKamioka (T2K) long baseline neutrino experiment. A total of 60,000 MPPCs will be used in the T2K near detector, the first time that MPPCs have been used on such a large scale. We have created a test bench to measure the gain, noise rate, crosstalk and afterpulse rate, and photon detection efficiency of 17,686 of these MPPCs. The results of these measurements are presented in this paper. © 2010 Elsevier B.V. All rights reserved.
