Matrix returns? (8 photos)

Who knows - what is it?





See the continuation of Japanese subatomic particle detector returns. Impressive Observatory is located at a depth of one kilometer underground in an old zinc mine under Mount Ikena in Japan. It consists of a vast "basement", filled with 50,000 tons of water and about 11,200 photomultiplier tubes.

Super-K was flooded in November 2001, when some of its pipe exploded because of overflow water. The resulting shockwave destroyed about 6,800 of the 11,000 tubes of the detector.















Despite this, now repair "glass cathedral" is over, and it will be recharged in June. To prevent another catastrophic accident, the detectors will be protected plexiglass and glass.

The observatory was known in 1998, when with the help of it has been proven that neutrinos have mass. In the future, Super-Kamiokande possible to study these difficult to obtain particles.
