Abstract Lockheed Martin’s Advanced Technology Center (LM-ATC) is developing the cryocooler system for the United States infrared instrument on the Russian-American Observational Satellites (RAMOS) under contract to the Space Dynamics Laboratory. The project is presently fabricating the engineering model, which consists of the cryocooler and electronic controller. LM-ATC s cryocooler is robust and simple, consisting of a two-stage coldhead with no moving parts, driven by a linear flexure-bearing compressor and powered by a high-efficiency electronic controller that includes ripple suppression and vibration cancellation. A distance of up to one meter separates the coldhead and compressor. The controller provides temperature control at 75K. The cryocooler is designed simultaneously to provide 0.75 W of cooling at 75K and 6 W cooling at 130K while rejecting heat at 313K. Total system power is 117 W and the exported vibration is less then 0.2N. This paper presents the status of the engineering model and overall system characteristics.
