Figure 3. Schematic CP15 installation for readout of a scintillation detector
The charge pulse from a scintillation detector is electrons, thus negative polarity. The CP15 can
handle positive or negative input pulses, but some readout devices might require a positive going
pulse. To set the CP15 to be overall inverting so that negative input charge gives a positive
voltage, the internal polarity jumper should be set to the default INV position.
9.3.2 Setup with the C400
The C400 is a partner product to the CP15. It provides pulse discrimination and counting
electronics for four independent channels, each of which provides the bias, pre-amp power and
signal processing for a detector system. Detector types can be mixed. The CP15 is well-suited
as a preamplifier for the C400 but can of course be used with other pulse handling electronics
also.
