The Ministry of Education, Culture, Sports, Science and Technology has decided to build a new generation facility “Hyper-Kamiokande” in Gifu Prefecture, which will succeed the elementary particle observation facility “Super-Kamiokande”, which has resulted in the Nobel Prize. We decided to include more than 10 billion yen in the request, including detector development costs.
“Hyper-Kamiokande” led to two Nobel Prizes, “Kamiokande”, the world ’s first successful observation of a kind of “cosmic neutrino”, and “Super-Kamiokande”, which captures the phenomenon called “neutrino oscillation” for the first time. This is the successor to the observation facility
A huge aquarium with a diameter of over 70 meters and a depth of 60 meters in Hida City, Gifu Prefecture, is planned to observe neutrinos, a type of elementary particles coming from space, with a highly sensitive detector.
The total construction cost was estimated to be more than 67.0 billion yen, and a survey cost to consider the significance of construction was recorded this fiscal year, but the Ministry of Education, Culture, Sports, Science and Technology has solidified its policy to start planning from the next fiscal year, We decided to include more than a billion yen in the development of new detectors and manufacturing costs in the budget request for next year.
The goal of full-scale operation is the second half of the 2020s, high results that approach the mystery that the universe was born by observing anti-neutrinos with the opposite properties of neutrinos and proton decay, which is a phenomenon that breaks down the protons that make up the nucleus Is expected.
