Improvements to the cooling power of a space qualified two-stage Stirling cycle cooler.

Summary

A long life two-stage cooler has been developed at Rutherford Appleton Laboratory for space purposes. This cooler is used for shield cooling and for precooling a Joule-Thomson stage for the production of temperatures below 4 K. The cooling power at 4 K can be increased by reducing the precooler temperature. An experimental programme has been conducted in looking at the effect of different regenerator materials on the cooling power of the cooler. The best cooler performance was obtained with a combination of lead wire and erbium(3)-nickel.
