A large-aperture photodetector is essential for a large-volume detector aiming at a neutrino physics and a nuclear decay search. Several new photodetectors with high resolution and efficiency have been developed for a one megaton water Čerenkov detector, Hyper-Kamiokande, planned in Japan. A proof test started in 2013 using a 200-ton water Čerenkov detector to evaluate feasibility of high quantu ... More

Hyper-Kamiokande is a proposed future neutrino experiment with various physics goals such as the discovery of leptonic CP violation, nucleon decay, supernova neutrino, and so on, using a 1 Mton water Cherenkov detector. Because of the large volume, About 99000 of 20 inch photosensors are planed to set in the detector. (About 9 times as many as 20 inch photosensor in Super-Kamiokande) Consideri ... More

Hyper-Kamiokande is a next generation huge water Cherenkov detector proposed for a discovery of proton decay and neutrino observations. It is planed to have 20 times larger volume than Super-Kamiokande, with 100,000 next generation photo sensors. One candidate of the sensor is a 50 cm Box-and-Line dynode photomultiplier tube (BL PMT), which have excellent time resolution and energy resolution. How ... More

Hamamatsu Photonics has been providing several types of vacuum photon detectors for HEP experiments in many years. We have been making effort to develop new products accordingly. In this time, fast time response PMT series is shown as example. It includes 4 kinds of PMT sizes from 1-inch to 2-inch. T.T.S. of 170 ps was achieved in 1-1/8-inch PMT. This fast time response PMT series is suitable for ... More
