31 March 1982 Two Years Orbital Performance Summary Of Stirling Cycle Mechanical Refrigerators
Author Affiliations +
Four Stirling cycle mechanical refrigerators are continuing to provide cooling to two gamma ray detector instruments after over 860 days in orbit. These units were developed jointly by North American Philips Laboratories and the Johns Hopkins University/Applied Physics Laboratory and placed into orbit on 24 February 1979 aboard the P78-1 spacecraft. The four units have demonstrated between 4,700 to over 16,000 hours of unattended operation and represent a major breakthrough in the lifetime capability of mechanical refrigerators.
