Abstract: The Advanced Baseline Imager (ABI) Pulse Tube Cooler System is a two-stage pulse tube cooler for space applications. The cooler incorporates an integral HEC (High Efficiency Cryocooler) pulse tube cooler and a remote coaxial cold head. The two-stage cold head was designed to provide simultaneous large cooling power at 53 K and 183K. This paper presents the data collected on the lifetest cooler during acceptance testing. Tests included thermal performance mapping at different heat rejection temperatures, cooler orientation relative to gravity and temperature stability tests. Designed for a 10-year life, the ABI coolers are required to provide 2.27 W of cooling at 53 K and 5.14 W of cooling at 183 K while rejecting to 300K with less than 143 W input power to the compressor. The ABI lifetest cooler meets the cooling requirement at 53 K while exceeding the requirements at the remote cold head (157 K vs. 183 K) and compressor input power (125W vs. 143 W).
