Air Heat-Exchanged Multi-Stage Series

Thermoelectric Photomultiplier Tube Chambers

for Tubes of 1.1" (30 mm) or less Nominal Diameter

This air heat-exchanged Multi-Stage series includes the TE328RF (end on), TE330RF (side on), TE331RF (end on), and TE332RF (side 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 with the Products for Research no-dew apparatus 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 TE328TSRF, TE330TSRF, TE331TSRF, and TE332TSRF respectively.

Chambers in this Multi-Stage series have been designed to accept all interchangeable options used in the standard line of cooled housings for 1.1 inch (30 mm) or less nominal diameter photomultipliers.
