9.3.8.4. PMT Cooler
The PMT cooler uses a Peltier cooler supplied with DC current from the switching power supply
in the Power Supply Module. An overall view is shown in Figure 9-11. The temperature is
controlled by a proportional temperature controller located on the Preamp board. The input
voltage from the supply is 15 VDC. Typical current through the cooler at room temp is about 1.5
to 2 A. At normal room temperatures the 7

C set point should be maintained within 0.1C. The
current and voltage can be measured at test points on the fan shroud at one end of the NO

sensor module. See the Schematic in the Appendix.
