Hyper-Kamiokande (Hyper-K) will be one of the biggest Neutrino detectors when commissioned in 2027.  It will consist of a cylindrical tank, with a water depth of 71m and a diameter of 68m. On the tank wall, 40,000 ultra-high sensitivity photosensors will be installed in order to detect the very weak Cherenkov light generated in the ultra-pure water. Hyper-K will be the 3rd generation of Kamioka neutrino detector. Previous two experiments, Kamikande and Super-Kamiokande have made very significant contributions in Neutrino physics. Both experiments have been awarded Nobel prizes for their contributions. 

Its Physics aims are (

  • Discovery of the difference between neutrino and antineutrino oscillations (CP violation) and precise measurements to elucidate the origin of matter in our universe and why our Universe is matter dominated
  • Precise measurements of neutrino oscillation parameters
  • Further development of neutrino astronomy : supernova neutrinos, neutrinos from other astrophysical sources
  • Proof of “unification of elementary particles” and “unification of electromagnetic, weak and strong force” by the discovery of proton decay

As of June 2022, researchers from 20 countries are participating in the experiment: Armenia, Brazil, Canada, Czech Republic, France, Germany, India, Italy, Japan, Korea, Mexico, Morocco, Poland, Russia, Spain, Sweden, Switzerland, UK, Ukraine, and the United States.

A workshop is planned on the 15th, 16th and 17th November 2022 at Vishwakarma Institute of Information Technology (VIIT), Pune to further strengthen India’s participation in HyperK and possibly nucleate a core group of Physicists and Engineers to form HyperK-India in the near future.

The workshop will open with presentations by researchers from HyperK who will elucidate the Physics as well as technology development plans to achieve the high precision and sensitivity of measurements by HyperK.  This will be followed by presentations of researchers from India who are already participating in HyperK and related experiments.  The researchers from India desirous of contributing to HyperK can also talk about their expertise and how they can contribute.  In the end the deliberations will be summarized and an action plan drawn up to initiate proposals for joint Indo-Japanese funding.
