Abstract : This report describes the physical characteristics of the final design configuration of the 1 Watt Split-Stirling Cryogenic Cooler. Qualification testing included evaluation of the 1.0 Watt Cryogenic Cooler under the following conditions: Performance tests over the temperature range of -40 degrees C to +55 degrees C; High and Low Temperature Shock Tests; Mechanical Shock Tests; Sinsoidal Vibration; Self-Induced Vibration; Acoustical Testing; and 1000-Hour Mean Time Between Failure Life Tests. The cryogenic cooler design consists of a motor and compressor assembly, and a remote expander assembly, interconnected by a stainless steel capillary line. The system is nominally a 18.5 VDC, 60 Watt cooler and has a maximum weight of 4 pounds. This report summarizes the results of the performance, environmental and life qualification tests conducted under the contract and provides supporting data for each of the test categories. (Author)
