Channel Photomultipliers and Modules
MD Series CPM Modules
Ultra High Sensitivity Gateable Channel
Photomultiplier DC-Modules
Description
The Channel Photomultiplier DC-
Module series is designed for all low
light applications e.g. in industries,
life science or medical analysis, in
high energy physics or pure research.
It is an easy to use module, containing
the Channel Photomultiplier,
a high voltage power supply, an
amplifier with I/U conversion
and an active quenching circuit for
high light protection. It is also
possible to apply an external gate
function. Strong variations in light
levels are possible due to the high
dynamic range of the installed CPM.
The exceptional low noise and high
sensitivity facilitates detection of
extremely low light levels.
Features
· High dynamic range
· No cooling required
· Very high stability in noise level
· Adjustable gain
· Active quenching
· Circuit for high light protection
· Gateable CPM input (only Bialkali types)
· Optical fiber read-out possible
· 5 volts operating voltage
· Monitor voltage output

CAUTION: HIGH VOLTAGE WARNING
This product operates at high voltage. Extreme care must be taken to ensure operator safety and to avoid damage to other
instruments. Avoid direct contact with the entrance window of the built in CPM when high voltage is applied. Avoid placing
conductive material close to the cathode.
Ensure that no light levels are applied, generating higher anode currents than specified.
All given values are nominal/typical @ 20 °C ambient temperature; specification subject to change without notice
