HPD (HYBRID PHOTO-DETECTOR) MODULES

PRELIMINARY DATA

H8236-07, -40

OCT. 2000

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