Cryogenic cooler system

Abstract

A cryogenic cooling system comprising a cold finger and a compressor unit connected by a compressor transfer line is provided, for example for cooling of a detector or similar device. Either or both of the cold finger and compressor unit which may be provided with one or more heat pipes passing partially or wholly through the mounting body of the cold finger and / or housing of the compressor. In preferred embodiments, each lumen is situated so as to pass through the greatest possible thickness of said mounting body, and as close as possible to the working fluid present therein, whilst ensuring the integrity of the cryogenic circuit. In preferred embodiments, where the cold finger and / or housing of the compressor are substantially cylindrical, the lumens provided for the heat pipes describe chords of the circular cross section.
