Contains about 1,885 8-inch PMTs that act as a "veto" to identify and exclude particles entering from outside the tank.
A cylindrical stainless steel tank measuring approximately 39.3 meters in diameter and 41.4 meters in height . Medium: It contains 50,000 tons of ultra-pure water . Super K
Contains over 11,000 20-inch PMTs that monitor the main water volume. Contains about 1,885 8-inch PMTs that act as
This report covers (often abbreviated as Super-K or SK ), a massive underground neutrino observatory located in the Kamioka Mine, Japan. Overview Contains over 11,000 20-inch PMTs that monitor the
Super-K has provided foundational evidence that has shaped modern particle physics.
The tank is lined with roughly 11,000 to 13,000 Photomultiplier Tubes (PMTs) .
When a neutrino interacts with water, it can produce a charged particle moving faster than the speed of light in water. This creates Cherenkov light , a faint blue flash detected by the PMTs. Scientific Achievements
