What is a "neutrino"

All photos of this post were taken in one of the most advanced and equipped laboratories in the world, which is called the Super-Kamiokande. It is located at an incredible depth of 1 kilometer in zinc Kamioka mine, and all the equipment installed in it only serves only one purpose - to study the unique elementary particles called neutrinos. Read and see further.

At kilometer underground in the Kamioka mine zinc miners do not work, and scientists - there is a laboratory with a neutrino detector Super-Kamiokande. It is designed to search for hypothetical proton decay, study neutrinos, as well as detection of the neutrino supernova explosions.
The detector is a stainless steel tank, 42 ​​meters high and 40 meters in diameter, filled with 50,000 tons of specially purified water. On the walls of the tank are placed 11 146 photomultipliers. Also, the detector is equipped with a large number of electronics, computers, calibration devices and equipment for water purification. It is extremely light-sensitive devices, in contact with the surface of a single quantum of light they generate an electrical impulse, which is then processed by a special electronic system.
