KAMIOKANDE (Kamioka Nucleon Decay Experiment)
The operation of KAMIOKANDE started in July 1983 to explain the stability
of protons and bound neutrons.
The detector was upgraded to detect low energy neutrino events.
Neutrinos coming from SN1987a was detected in 1987.
Neutrinos from the sun was measureed in 1988.
KAMIOKANDE Detector.
To detect charged particles, the KAMIOKANDE detector utilizes Cherenkov
radiation in the water.
Cherenkov radiation is generated when a charged particle pass through
the matter with velocity greater than that of light in the matter.
Cherenkov photon is detected by the 20"PMT which is attached inside
of the water tank.
Awing to a total of 2140 t of water, KAMIOKANDE can detect rare events
such as a nucleon decay and a neutrino event.
Super Kamiokande has been under construction since 1991, and will start its
full operation in 1996.
In Super Kamiokande, significantly higher statistics will be obtained
with better dtector performance than the current KAMIOKANDE.
