The First Meeting of the Hyper-Kamiokande Experiment Financial Forum


The first meeting of the Hyper-Kamiokande Experiment Financial Forum (HKFF), in which foreign agency representatives gathered to engage in discussion with host organizations and project members, was held at Kojima Hall, Hongo Campus, the University of Tokyo on January 11th, 2019.

Hyper-Kamiokande (HK) is a new world-leading international scientific research project aiming to start its operation in the second half of the 2020s. The HK detector is planned to have eight times larger fiducial mass than its predecessor detector, Super-Kamiokande, and it is equipped with newly developed high-sensitivity photosensors. The aim of HK is to elucidate the Grand Unified Theory and the history of the evolution of the universe through an investigation of proton decay and CP violation (the difference between neutrinos and antineutrinos), together with the observation of neutrinos from supernova explosions.

Professor Takaaki Kajita, the director of NNSO, invited foreign agency representatives and researchers from 14 countries (Armenia, Brazil, Canada, France, Italy, South Korea, Poland, Russia, Spain, Sweden, Switzerland, UK, USA and Japan) and about 50 people gathered to hold discussions.

Prof. Kajita Calls on Participants to Further Solidify International Collaboration

In the meeting, Professor Kajita made an opening address saying, “The forum was established to offer a place for agencies to find out the details of the Hyper-Kamiokande project including its goals, timelines and the organizational structure, and to share information on interests and constraints of each country and region. We’d like to have discussions to identify the necessary tasks to further solidify the international collaboration.” The President of the University of Tokyo, Makoto Gonokami, said, “Of course, this project cannot be realized by the University of Tokyo alone. Cooperation with international partners, as well as the High Energy Accelerator Research Organization (KEK) and other institutes in Japan, is indispensable. We look forward to closely working with you in the future, and hope that this meeting will be the first step towards our fruitful collaboration and the success of realizing this exciting project.”

About 25 Participants Make a Visit to the Super-Kamiokande

On the next day, January 12th, about 25 participants made a visit to the Super-Kamiokande detector in Hida City, Gifu Prefecture, whose tank is almost full of water after undergoing refurbishment work.
