Summary

A SURPRISINGLY WIDE DIVERSITY OF SENSORS, INSTRUMENTS OR DEVICES USED FOR MILITARY, CIVIL, SCIENTIFIC AND MEDICAL PURPOSES REQUIRE COOLING TO CRYOGENIC TEMPERATURES. SOME WORK BETTER OR FASTER AT LOW TEMPERATURES, ARE MORE SENSITIVE OR MORE EFFECTIVE. FOLLOWING A LONG PERIOD OF INTENSIVE DEVELOPMENT AND EVALUATION OF MANY DIFFERENT MECHANICAL SYSTEMS MINIATURE STIRLING ENGINES APPEAR TO EMERGE AS THE SYSTEM OF CHOICE. THEY ARE SMALLER, WEIGH LESS, ARE MORE EFFICIENT AND CAN BE MADE AT A REASONABLE PRICE. EARLY DISAPPOINTMENT WITH LIMITED LIFE AND HIGH MAINTENANCE REQUIREMENTS HAVE BEEN ALLEVIATED AS THE TECHNOLOGY MATURES, DESIGNS ARE STABILIZED AND MANUFACTURING AND TEST TECHNIQUES DEVELOP.
