1 About this User’s Manual Volume 1
CSA
Canadian Standard Association: sets norms and standards that are
important for Canada (and America), among other things, the
Directive for Explosion Protection and Low Voltage.
PMT
Photomultiplier or only multiplier: converts the flashes of light gen-
erated by the radiation in the detector into electrical signals.
HV
HV = High voltage
The multiplier is operated at high voltage, so that flashes of light
can be converted into electrical pulses.
The high-voltage control allows for measurements that are stable to
temperature and aging. Each multiplier has a slightly different sen-
sitivity, and must therefore be operated at a different high voltage.
active / passive (Source / Sink)
Depending on the detector type, the current output can be config-
ured as a current source or current sink. The following terms are
used interchangeably:
• Current source: active / Source Mode
• Current sink: passive / Sink Mode
