General Description
The Image Photon Detector (IPD) System , now in is 3rd generation is a true single photon counting
system which offers the ability to capture and integrate an image in real time Unlike our HRPCS systems,
the IPD detector is a serial device. It is capable of measuring only one event at a time and has the ability
to record the arrival time of the event to nano-second accuracy.

Principle of Operation
The IPD3 camera uses Photek’s Image Photon Detector (IPD) as the primary method of photon
amplification in conjunction with a propriety electronic readout system.

Incident photons pass through the input window and hit the photocathode.
Photoelectrons are released from the photocathode and are accelerated by a potential field to the
micro-channel plate.

The photoelectron is amplified by a factor of 10 by the stack of MCPs. The actual gain of the
detector can be adjusted by varying the voltage across the MCPs.
The cloud of electrons emitted from the MCP is collected an anode.
The IPD detector normally used a resistive anode which has for corners labelled A,B,C and D.
Depending on the position of the event charge is proportionally split to each of the outputs (other
anodes are available on request).
Signal from the anode is then amplified by four separate charge sensitive amplifiers and a
discriminator before being digitised and processed.
