Photosensor cover development by Spanish collaborators

Ultra-sensitive photosensors with a diameter of 50 cm are used in the Hyper-Kamiokande. The photosensor has adequate water pressure resistance for use in water of the detector, and installing photosensor cover will increase safety. Hyper-Kamiokande is an international research collaboration, with various countries sharing the research and development work. The Spanish group is playing a […]

Excavation for the Hyper-Kamiokande access tunnel has begun

The access tunnel excavation for the Hyper-Kamiokande project begun on the 6th May. Following the completion of the entrance yard construction, the excavation work started in earnest. An approximately 2km long tunnel will be rapidly excavated in 9 months followed by the excavation of approach tunnels and the main cavern. With preparations going smoothly, the […]

The production of Hyper-Kamiokande photosensors has begun

Charged particles generated by high-energy events, such as neutrino interactions or proton decay, emit Cherenkov light when they pass through the water. Photosensors attached to the wall of the Hyper-Kamiokande tank are used to collect this Cherenkov light. The light collected is then used to identify the type of each particle and to measure their […]

Hyper-Kamiokande elects spokespeople

With the approval of the Hyper-Kamiokande experiment in Japan and the approval of the collaboration agreement, Hyper-Kamiokande moved in June 2020 from a proto-collaboration to a collaboration. The collaboration elected its first co-spokespersons in December 2020: Prof. Masato Shiozawa (as the Japanese spokesperson from ICRR University of Tokyo, Japan) and Prof. Francesca Di Lodovico (as […]

Hyper-Kamiokande Experiment to Begin Construction in April 2020

Last week at the 7th Hyper-Kamiokande proto-collaboration meeting, a statement was issued by the University of Tokyo recognizing the significant scientific discoveries which the planned Hyper-Kamiokande experiment would enable. It states that, based on these exciting prospects, the University of Tokyo will ensure that construction of the experiment will begin in 2020. Hyper-Kamiokande now moves from planning […]

The Hyper-Kamiokande Project is in the MEXT Large Projects Roadmap

Hyper-Kamiokande (Hyper-K), a third generation Water Cherenkov detector and the latest in an illustrious series of world-leading experiments located in Japan, is being developed by an international collaboration. It will take advantage of its predecessors: the double Nobel prize winning experiment (Super-)Kamiokande and the extremely succesful K2K (1999-2004) and T2K (2010-) long baseline neutrino experiments.
