Liquid Heat-Exchanged Multi-Stage Series

Thermoelectric Photomultiplier Tube Chambers

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

The liquid heat-exchanged Multi-Stage series for MCP PMT's includes the TE314RF,  TE315RF,  TE354RF, and the Economical TE454RF thermoelectrically cooled photomultiplier tube chambers. These chambers utilize cascaded 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 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 TE314TSRF,  TE315TSRF,  TE354TSRF, and  TE454TSRF respectively.

Liquid heat-exchanged thermoelectrically cooled PMT housings typically use water, either by means of a recirculating liquid heat exchanger, or tap water flowing into an open drain to remove heat from the PMT cooler. Other non-hazardous liquids may also be used.

Chambers in this Multi-Stage 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
