Type: Oral Presentation
Session: Photon Detectors
Track: Photon Detectors
We report on the development of a large-aperture Hybrid Avalanche Photo-Detector (HAPD).We have developed an 8-inch aperture HAPD and its readout system.The HAPD is a photo detector expected to replace the photomultiplier tube (PMT) in next-generation imaging water Cherenkov detectors such as Hyper Kamiokande. HAPD has shown its excellent performances, 7 times better time resolution and 3 times better pulse height resolution, compared to PMT. We will present the recent progress made in all glass HAPD to reduce its production cost, its performances including improved dark count rate, and readout system development.
