Neutrino astronomy is astronomy based on the observation of neutrinos. Neutrinos are observed using an apparatus consisting of photomultiplier tubes placed on the walls of a huge underground water tank. These instruments detect neutrinos by capturing the faint Cherenkov light. This light is emitted by secondary particles (such as electrons) that are produced when neutrinos interact with the water inside the tank.
Matsusada Precision manufactures and sells high-voltage power supplies for photomultiplier tubes, which are used to detect faint light in scientific analyzers and other sensitive instruments.
