Air Heat-Exchanged Multi-Stage Series

Thermoelectric Photomultiplier Tube Chambers

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

This marked, air heat-exchanged Multi-Stage series includes the PC328CE (end on), PC330CE (side on), PC331CE (end on), and PC332CE (side on) thermoelectrically cooled PHOTOCOOL, 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 PC328TSCE, PC330TSCE, PC331TSCE, and PC332TSCE 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.
