Liquid Nitrogen

Cooled Photomultiplier Tube Chambers

for PMT's of 65 mm, 53.4 mm, and 30 mm Nominal Diameter and MCP PMT's of 64 mm Nominal Diameter

This Liquid Nitrogen Cooled series includes the TE166TSRF (end on), TE176TSRF (end on), TE183TSRF (side on), TE193TSRF (side on), and TE335TSRF (end on) LN2 cooled photomultiplier tube chambers. These chambers utilize ColdZone temperature controlled LN2 flow to achieve temperatures needed for superior detector performance. 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, Digital PID Temperature Control and the appropriate PMT socket assembly. Chambers in the Liquid Nitrogen Cooled series have been designed to accept all 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.
