Liquid Heat-Exchanged and Air Heat Exchanged

Thermoelectric Photomultiplier Tube Chambers

for Microchannel Plate Photomultiplier Tubes of 70 mm, 64 mm and 45 mm Nominal Diameter

This marked, liquid heat-exchanged and air heat-exchanged thermoelectric PHOTOCOOL series of cooled housings for MCP PMT's includes the PC268CE, PC271CE, PC321CE, and PC352CE 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 MCP PMT coolers are provided complete with magnetic, electrostatic and RFI shielding, a double pane evacuated window cell 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 PC268TSCE, PC271TSCE, PC321TSCE, and PC352TSCE respectively.
Chambers in this standard series have been designed to accept most 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
