Hyper-Kamiokande is the next generation water Cherenkov detector for the study of neutrino oscillations including the search for leptonic CP violation using high intensity neutrino beam produced in J-PARC. In order to reduce the systematic uncertainty of the CP violation measurement, a 1kton scale Intermediate water Cherenkov detector (IWCD) is planned to be constructed around 1km downstream the J-PARC neutrino beamline. The multi-PMT modules, which consist of 19 3-inch PMTs will be installed in the IWCD to improve the detector performance with their higher granularity.
In this poster, we will present the measurements of the performance for 3-inch PMT such as time resolution, dark noise rate and relative photon detection efficiency.
