HPD (HYBRID PHOTO-DETECTOR) MODULES PRELIMINARY DATA OCT. 2000 H8236-07, -40 PATENT PENDING The HPD (Hybrid Photo-Detector) is a new vacuum photo-detector including a photocathode and an avalanche diode. The HPD provides a gain of more than 1000 in a single multiplication process called 'electron bombardment multiplication'. The photoelectrons from the photocathode are accelerated by a strong electric field to hit the avalanche diode and release a large number of electron-hole pairs corresponding to the acceleration energy. This excellent first multiplication process enables the HPD to achieve excellent multi-photon energy resolution. This first multiplication process is followed by the second avalanche mode multiplication to provide sufficient gain for a variety of applications.
