Abstract

Recent emphasis on energy conservation has resulted in new efforts to develop more efficient, long-life refrigeration techniques for the DSN maser. As the new techniques are developed, a comparison of their reliability and efficiency to those of the closed-cycle helium refrigerator presently used will have to be made. Measurements of the refrigeration capacity have been made on an existing refrigeration system as a function of the supply pressure and the return pressure in the Joule-Thomson circuit. The performance of the refrigerator has been calculated and compared to the ideal Carnot-cycle refrigerator.
