Hyper-Kamiokande detector and its capabilities in astrophysical neutrino search

Abstract Hyper-Kamiokande (Hyper-K) is a next generation underground large water Cherenkov detector. Its tank will be filled with 260000 metric tons of ultra-pure fiducial volume 0.19 Mtons, which about 8 times larger than that its predecessor Super-Kamiokande. In volume, light produced by neutrino interactions and detected newly developed photo sensors installed in dedicated frame. Two different kinds photo-detectors systems are considered for Hyper-K: 20-inch PMT multi-PMT (mPMT). particular, the mPMT system consists pressure sealed vessel 19 3-inch PMTs inside. This configuration was implemented first time KM3NeT experiment, has been demonstrated to improve Hyper-K physics capabilities [1, 2]. located Kamioka mine (Japan), where cavern under 600m-high mountain being excavated installation With fruitful research program, play highly significant role frontier, particular CP violation, including astrophysics providing important information from measurements. The potential program discussed this contribution.
