Masatoshi Koshiba

Masatoshi Koshiba - (born on September 19, 1926 in Toyohashi, Aichi Prefecture) - Japanese physicist, Nobel Prize winnet in Physics in 2002 (half of the prize with Raymond Davis "for the creation of neutrino astronomy").

In March 1970, Koshiba became a professor at Tokyo University.

In the 1950s and 1960s, Koshiba was studying the high-energy cosmic radiation and related phenomena in the upper atmosphere. In 1970, these studies led him to the muon and neutrino physics and the physics of elementary particles. After participating in the JADE - a joint German-Japanese project on the accelerator DESY in Hamburg, he designed Kamiokande detector to record the proton predicted by the disruption theory. Since the registration of proton was not successful, he rebuilt the detector in the neutrino detector and was able to register cosmic neutrinos in the process of explosure of supernova 1987A managed to register 12 neutrinos, 9 of which were in the first 2 seconds. This was the first direct experimental evidence of the theories about the processes occurring in the collapse of the star, in particular the theory of neutrino cooling. In 2002, he was awarded the Nobel Prize for physics. Together with Raymond Davis, he received half of the prize, the second half was Riccardo Giacconi.
