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. The neutrinos are observed by detecting the weak light emitted by the neutrinos entering the tank.
Matsusada Precision manufactures and sells high-voltage power supplies for photomultiplier tubes that are used to detect weak light in analyzers and other devices.
