Description
Hyper-Kamiokande (Hyper-K), a proposed one-megaton water Cherenkov detector to be built in Japan, is the logical continuation of the highly successful program of neutrino (astro)physics and proton decay using the water Cherenkov technique. In its baseline design, the Hyper-K detector consists of two cylindrical tanks lying side-by-side, the outer dimensions of each tank being 48m x 54m x 250m. The inner detector region will be instrumented with 99,000 20-inch photo-sensors.
Hyper-K will offer a broad program of physics and astrophysics, such as precise measurements of the lepton mixing matrix and leptonic CP asymmetry with accelerator and atmospheric neutrinos, a search for the nucleon decay with an order of magnitude better sensitivity, and other researches in particle and astroparticle physics with extraterrestrial neutrinos.
An international collaboration has been intensively working on the R&D of key components such as optimization of cavern and tank construction, development of high performance photosensors, calibration, readout and trigger systems, design of new near detectors, J-PARC neutrino beam improvement, and development of simulation and reconstruction software. The overview of R&D and the status of project will be presented
