This photomultiplier tube represents Masatoshi Koshiba's research at the Kamiokande and Super-Kamiokande facilities in Japan. These large facilities are located in a water-filled mine. More than 1,000 photomultiplier tubes were placed in the Super-Kamiokande.
Neutrinos are elusive particles that can arise in nuclear reactions in the sun and during supernova explosions. Only one in a trillion neutrinos are stopped on their way through planet earth. When this happens, an electron is formed that generates a small flash of light. To prove the existence of neutrinos, Masatoshi Koshiba used photomultipliers like this one. The photomultiplier captured the flashes and amplified them so that they could be registered.
Masatoshi Koshiba donated the photomultiplier to the Nobel Prize Museum in 2002. - Pristagare
