Description

The H8236 HPD (Hybrid Photo-Detector) is a new vacuum photo-detector including a photocathode  and an avalanche diode. The H8236 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.

H8236 is an HPD module, containing high voltage power supplies and a pre-amplifier.
