Abstract
Not Available We propose an affordable, compact, reliable, lightweight, and efficient 10K refrigerator for superconducting electronics applications. Recent advances show an improved 10K refrigerator can be developed. Significant progress developing Gifford-McMahon, Stirling, and Pulse Tube refrigerators for high-temperature superconducting (HTS) electronic applications has demonstrated several characteristics needed for an improved 10K refrigerator. Improvements in regenerator materials such as textured neodymium ribbon offer enhanced regenerator performance at temperatures below 10K. We will integrate these and other recent developments into a single refrigerator concept. The thermodynamic cycle, compressor and expander technology, regenerator materials and geometry will be selected by comparing the performance of existing components to requirements for superconducting electronics applications. Critical thermodynamic and engineering choices will be modeled, and we will select a baseline approach for Phase II. To focus concept development and guide Phase II and Phase III planning, candidate applications will be selected in consultation with potential customers and the Navy. In Phase II, we will complete detailed design, build and test the baseline refrigerator, and verify that performance meets the requirements for the Phase III application(s). In Phase III, we will partner with a vendor of superconducting electronics to build a fully integrated system (e.g. voltage standard or analog-to-digital converter.
