Hyper-Kamiokande is a neutrino observatory being constructed on the site of the Kamioka Observatory, near Kamioka, Japan. Among the main scientific objectives will be the search for proton decays, and to detect neutrino emission from astrophysical sources. Researchers from the JU Astronomical Observatory, Krzysztof Ziętara, Prof. Michał Ostrowski and Dr hab. Łukasz Stawarz, are involved in the Hyper-Kamiokande project.
Hyper-Kamiokande will have a tank with a billion litres of ultrapure water, 20 times larger than the tank for Super-Kamiokande. This increased capacity will be accompanied by a proportional increase in the number of sensors. The tank for Hyper-Kamiokande will be a cylinder 71 meters tall with 68 meter diameter, and buried 650 meters deep to reduce interference from cosmic radiation.
The excavation of the dome section of the Hyper-Kamiokande main cavern was completed on 3 October. The Hyper-Kamiokande dome with a diameter of 69m and a height of 21m is one of the largest human-made underground space.
