Compressor Cooled

Photomultiplier Tube Chambers

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

This Compressor Cooled series includes the TE222RF (end on), and TE254RF (end on) Compressor cooled photomultiplier tube chambers. These chambers utilize high performance detachable, temperature controllable compressors 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. Digital PID Temperature Control is available as Option 36, and if included, changes the type numbers to TE222TSRF, and TE254TSRF respectively. Chambers in the Compressor 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.
