Air Heat-Exchanged Thermoelectric

Cooled Photomultiplier Tube Chambers

for Tubes of 2.1" (53.4 mm) or less Nominal Diameter

This marked, air heat-exchanged PHOTOCOOL, series includes the PC182CE (end on), PC212CE (side on), and PC312CE (end on) thermoelectrically cooled photomultiplier tube chambers. These chambers utilize single stage Peltier devices to achieve temperatures needed for superior detector performance, while maintaining the convenience of thermoelectric cooling. These PMT coolers are provided complete with magnetic, electrostatic and RFI shielding, a double pane evacuated window cell (PC182CE and PC212CE), or a single pane window (PC312CE), designed to prevent formation of condensation in the light path, the low voltage DC power supply to drive the Peltier devices, and the appropriate PMT socket assembly. Digital PID Temperature Control is available as Option 36, and if included, changes the type numbers to PC182TSCE, PC212TSCE, and PC312TSCE respectively. Chambers in the air heat-exchanged standard series have been designed to accept all interchangeable options and accessories used in conjunction with the PHOTOCOOL line of cooled housings for 2.1 inch (53.4 mm) or less nominal diameter photomultipliers.
