Hyper-Kamiokande Experiment to Begin Construction in April 2020

On Sept 12th, Prof T. Kajita, 2015 Nobel Prize Laureate and Director of the Institute for Cosmic Ray Research (ICRR), University of Tokyo, on behalf of the University of Tokyo, host lab of the Hyper-Kamiokande experiment together with KEK, announced that the construction of the Hyper-Kamiokande experiment will start in 2020 (

The Hyper-Kamiokande experiment is the next generation, state-of-the-art flagship neutrino experiment will be constructed near Kamioka, roughly 300 km from Tokyo, Japan. targeting a broad physics program consisting of neutrino oscillations, nucleon decays, and astrophysical neutrinos with unprecedented precision.

Hyper-Kamiokande will be the third-generation underground water Cherenkov detector in Japan following on from Kamiokande and Super-Kamiokande experiments whose discoveries were awarded the 2002 and 2015 Nobel Prizes, respectively.

The QMUL Hyper-Kamiokande group has a strong leadership in the experiment as well as giving strategic contributions to the detector construction on the Outer Detector, Data Acquisition and Calibration. We are also involved in Computing and Physics as well as contributing to a new Water Cherenkov near detector, E61.
