Research abstract
MANY MATERIALS, SUCH AS DOPED SI AND GE, REQUIRE LOW OPERATING TEMPERATURES FOR OPERATION. ELEMENTAL SUPERCONDUCTORS, SUCH AS NB, MUST BE OPERATED BELOW THEIR TRANSITION TEMPERATURES, WHICH DO NOT EXCEED 9 KELVIN. THE EXISTING CRYOCOOLER CYCLES, EVEN IF THEY CAN REACH THESE TEMPERATURES, ARE VERY INEFFICIENT BECAUSE OF POOR REGENERATOR PERFORMANCE. THE PROPOSED EFFORT COVERS THE DEVELOPMENT, USING AN INNOVATIVE CONCEPT, OF IMPROVED LOW TEMPERATURE REGENERATORS. THIS COULD, IF SUCCESSFUL, MAKE HIGH EFFICIENCY, LOW TEMPERATURE REGENERATIVE CRYOCOOLERS POSSIBLE.
