Dry Ice (Solid CO2) Cooled

Photomultiplier Tube Chambers

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

This Dry Ice Cooled series includes the TE159RF (30 mm side on), TE173RF (65 mm end on), TE218RF (30 mm end on), and TE241RF (53.4 mm end on), Dry Ice cooled photomultiplier tube chambers. These chambers utilize crushed dry ice in highly efficient heat exchangers 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, and the appropriate PMT socket assembly. Chambers in the Dry Ice 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.
