Hybrid Photodetector (HPD) is being developed for Hyper-K and a proof test is planned using a 200-ton tank at Kamioka site.
The development of an 8-inch HPD and a plan for the first proof test will be shown.

The next generation neutrino experiments call for significantly increasing the total detector volume. Inexpensive PMTs with large size and high efficiency photocathode are needed in order for these experiments to become reality. We have developed a conceptual design of large focusing type PMT aiming for improving the PMT photon detection efficiency. The transmission photocathode coated on the...

Photo-detector development for maximizing the overall photon detection efficiency
The baseline Hyper-K concept relies on 99,000 20” photomultiplier tubes (PMTs) to provide 20% photo-coverage. We are investigating solutions that would enhance the photo-coverage without compromising either contrast or timing resolution. Contrast roughly quantifies the fraction of photons detected that retain...
