Characterization of Raytheon’s 60 K 2W Protoflight Spacecraft Cryocoolerich uses a mass balancer to reduce vibration. It is designed to lift a heat load of 2W at 60K, with a nominal rejection temperature of 300K. The characterization of the PSC involved a series of experiments, including cool-down to lowest temperature, design point verification, parameter optimization,

Development of a 12 K Stirling Cycle Precooler for a 6 K Hybrid Cooler System is a continuance of our previous work on linear Stirling coolers. We have developed one-, two-, and three-stage Stirling coolers for various NASA and Department of Defense programs. For the Explorer 6 K, we have focused on adapting our three-stage Stirling cooler for operation at lower temperatures

Thermodynamic Optimization of Multi-Stage Cryocoolersme typically available to perform optimization procedures combined with the large number of variables and their complex interaction results in sub-optimal products. This paper presents a concept for optimization that more rapidly converges on an optimal design.
