Liquid Heat-Exchanged and Air Heat Exchanged Standard Series

Thermoelectric Photomultiplier Tube Chambers

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

The liquid heat-exchanged and air heat-exchanged thermoelectric standard series cooled housings for MCP PMT's includes the TE352RF,  TE271RF,  TE321RF, and TE268RF 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 TE352TSRF, TE271TSRF, TE321TSRF, and TE268TSRF respectively. Chambers in this standard series have been designed to accept most interchangeable options and accessories used in conjunction with the standard line of cooled housings for 2.1 inch (53.4 mm) or less nominal diameter photomultipliers
