Hyper-Kamiokande

Hyper-Kamiokande is a planned neutrino observatory to be built on the premises of the Kamioka Observatory near Kamioka , Japan .

This project started in 2010 as the successor to Super-Kamiokande . The start of construction for 2018 was announced in autumn 2017; scientific observations are to begin in 2025. Construction was finally approved on December 13, 2019 and is scheduled to begin in April 2020.

Hyper-Kamiokande will have a tank with a capacity for one billion liters of ultrapure water , making it 20 times larger than the tank for Super-Kamiokande. This capacity expansion is accompanied by a proportional increase in the number of sensors. The tank for Hyper-Kamiokande will have a double cylinder measuring 250 meters in length, 40 meters in width and 40 meters in depth and located at a depth of 650 meters in order to reduce interference from cosmic rays . One of the scientific goals is the first observation of proton decay .
