New large aperture, hybrid photo-detector and photo multiplier tube for a gigantic water Cherenkov ring imaging detector

We are developing a 20-in. aperture high quantum efficiency photo-multiplier tube (PMT) and a hybrid photo-detector (HPD) for Hyper-Kamiokande which is a next generation underground large water Cherenkov detector. We have measured prototypes of 20-in. PMT with a high quantum efficiency photocathode,...
