Super-Kamiokande (16 photos)

Stunner Super-Kamiokande represents a huge underground tank (cylinder diameter 39 and height 41 m) filled with 50 thousand tons of ultrapure water. On the walls of the reservoir with 11,000 photomultipliers, "browsing" the entire volume of water and detecting Cherenkov radiation particles. The large thickness of soil above the unit protects it from cosmic-ray background, so that the volume setting occur only rare events of which the most interesting are those that induced by solar or atmospheric neutrinos. In the research program also search for proton decay, detecting neutrinos from supernovae appealing, accelerator and astrophysical neutrinos.
