Description
The Hyper-Kamiokande (Hyper-K) is the third generation of underground water Cherenkov detectors in Japan. It will serve as: (1) the far detector for a long-baseline neutrino oscillation experiment for the upgraded, 1.3 MW power, J-PARC muon neutrino/antineutrino beam, and (2) a detector capable of observing proton decays, atmospheric neutrinos, and neutrinos from astronomical sources. The fiducial region of the Hyper-K detector, with a mass of 186 kton, will be instrumented with 20,000 20-inch photomultipliers (PMTs) and 800 multi-PMT modules, each containing 19 3-inch PMTs. Assembly and testing of detector components are underway, and operation is scheduled to begin in 2028. The Hyper-K status, research program, and sensitivities to different processes, including proton decay and CP violation in the neutrino sector, will be presented.
