PRELIMINARY DATA
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 photo-
cathode 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 resolu-
tion. 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.
A
at 8 V (or set the HV knob to -8 kV on the front panel of the HPD module power supply C8237) to PIN 8 and 7.5 V (or set the C8237 diode bias
voltage to +150 V) to PIN 6
B
or "-3 kV" to "-8 kV" high voltage on the C8237 front panel
C
or "70 V" to "152 V" diode bias voltage on the C8237 front panel
D
The characteristics of the bias voltage vs. avalanche gain curve of the diode inside are affected by the ambient temperature conditions, and even
under the same ambient temperature conditions resulting curve may differ between diodes from different production lots. Refer to the individual
data sheet attached to the module.
E

F

G
at 3 V (or set the C8237 HV knob to -3 kV) to PIN 8 and 7.5 V (or set the C8237 diode bias voltage to +150 V) to PIN 6. Input light pulse: 50 ns
(FWHM), 200 kHz.
