Development of a Low Noise 10K J-T Refrigeration System

Abstract

This report summarizes work done on the development of a low noise, Joule-Thomson, microminiature refrigeration system. Progress has been made on the development of the pneumatic compressor drive system which will be used to operate the compressor to determine the compressor lifetime and refrigerator system performance. Work on the refrigerator itself also has progressed well with operation down to 20K now being achieved, and reliably reproduced. Work is underway on the heat exchanger section of the third stage of the refrigerator, the helium stage.
