Super K -

Contains over 11,000 20-inch PMTs that monitor the main water volume.

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 Super K

The tank is lined with roughly 11,000 to 13,000 Photomultiplier Tubes (PMTs) . Contains over 11,000 20-inch PMTs that monitor the

Super-K has provided foundational evidence that has shaped modern particle physics. Contains over 11

This report covers (often abbreviated as Super-K or SK ), a massive underground neutrino observatory located in the Kamioka Mine, Japan. Overview

The detector is a feat of engineering located 1,000 meters (3,300 feet) underground to shield it from cosmic radiation.
