Outline of Final Research Achievements |
A Hybrid Photo-Detector (HPD) has a great potential to improve various physics sensitivities of Hyper-Kamiokande, which is a next generation large water Cherenkov detector. In order to demonstrate the performance for a long period, its usability was evaluated in a 200 ton water Cherenkov detector. At first, the 20 cm HPD was developed and eight of them were tested into the 200 ton water tank for two years. With a successful development of the preamplifier, the largest 50 cm aperture HPD was completed to detect a single photo-electron with high resolutions.
