On July 31, 2025, the Hyper-Kamiokande collaboration completed the excavation of the colossal cavern that will house the main detector volume of Hyper-Kamiokande, a next-generation ultra-pure water Cherenkov detector currently under construction in the city of Hida, Gifu, Japan.
The Hyper-Kamiokande (HK) project is an international scientific research collaboration led by the University of Tokyo and the High Energy Accelerator Research Organization (KEK) that aims to discover the subtle asymmetry between matter and antimatter in neutrinos and observe the interior of stars as a neutrino telescope. In addition, Spanish companies are beginning construction of several components of this gigantic experiment for installation in 2027.
The Laboratorio Subterráneo de Canfranc coordinates Spain’s contribution to the construction of Hyper-Kamiokande, funded by MICIU and the European Union’s Next Generation EU/PRTR program. Once the design is complete, Spanish companies will begin construction of several components of this gigantic experiment for subsequent installation in 2027.
