Abstract Two technology areas have been investigated recently at Raytheon Infrared Operations (RIO). First, we have developed a small cryocooler with good performance at high operating temperatures. The design approach for this cryocooler will be reviewed, and the measured performance data at the integrated dewar/cooler assembly level will be presented, with emphasis on performance at high operating temperatures. The first production run of over 100 cryocoolers was recently completed. Second, the design of a long-life compressor for tactical cryocoolers was completed. A flexure bearing suspension system is used in order to minimize contact between the pistons and their cylinders. The flexure design is challenged by severe constraints in terms of package size and overall compressor mass. The design approach and the resulting configuration is described.
