Description

T2K is a long-baseline neutrino oscillation experiment. T2K collaboration is planning to upgrade the near detector to better constrain neutrino interaction systematics. Super-Fine Grained Detector(SFGD) will be a new detector in the upgraded detector. SFGD utilizes 56,384 multi-pixel photon counters(MPPC), so it is important to understand their behaviour before installation. A performance test for those MPPC-PCBs is performed. In the test, I measure and analyze their dark noise, gain, photon detection efficiency, cross talk and operation voltage.
In this work, I will present the design and validation of the test system and report the latest measurement results.
