Hyper-Kamiokande or Hyper-K is the next generation Water Cherenkov detector being constructed in Kamioka, Japan, following the successful running Super-Kamiokande experiment. The Hyper-Kamiokande will not only measure neutrinos from the accelerator at J-PARC, Tokai in Japan, as a long-baseline neutrino experiment but also from the natural sources like the sun and the atmosphere.
The design and construction of the detector is progressing currently, and the experiment is expected to start taking data in 2027. Apart from advanced PMT configurations, the Hyper-K will also have an Intermediate Water Cherenkov Detector (IWCD) at a distance of approximately a km
from the neutrino-source,
while the far detector will be located 295 km away.
The designs and status of this enormous detector Hyper-K, which is currently under-construction, the status of the near or intermediate detectors,
and the main and expected physics capabilities of the experiment are described in this report.
