Abstract:

Future MDA missions will require various enhancements in multi-stage cryocoolers. These include increased efficiency, reduced vibration and reductions in overall system mass and power consumption. For the small coolers required, pulse tube and Stirling coolers offer the best opportunities. At present, the efficiency of these coolers is limited by the effectiveness of low-temperature-stage regenerators. Below about 60 K, two factors play key roles in reducing the effectiveness of regenerators. One is that the heat capacity of most materials falls rapidly with decreasing temperature, thereby, severely limiting the number of useful materials to a few in common use. A second factor is that these commonly used materials are only available in powder form, a form known to raise reliability issues. In this effort, we will address both factors. We will use newly developed materials with high heat capacities at temperatures below 60 K, higher than that of commonly used materials. Further, we will use a novel low-temperature regenerator matrix that will address both the aspect of high-efficiency and regenerator durability. Both the void fraction and the ratio of surface area to solid fraction of the regenerator matrix will be varied to achieve high efficiency
