We have developed a multichannel Hybrid Photo-Detector with fast time response, good timing resolution and low noise after a genuine signal (afterpulse). For this purpose, a prototype has been developed to encapsulate a newly designed multichannel av

We have newly developed a Hybrid Photo-Detector (HPD) with 2-inch diameter. It consists of a bialkali photocathode and a 3 mm x 3 mm Multi-Pixel-Photon Counter (MPPC) sealed in a glass tube. The electric field inside the tube is designed so that phot

A hybrid photodetector (HPD) combined with a III-V photocathode is considered to be an ideal photodetector, because the quantum efficiency (QE) is high, the collection efficiency is 100%, and the excess noise factor is negligible. As the first step,
