Type of article: Article
Summary
A COMPLETE HYDRIDE REFRIGERATOR SYSTEM HAS ACCUMULATED MORE THAN 1,000 H AT 29 K OR BELOW (14 K MINIMUM). A METAL HYDRIDE COMPRESSOR, WITHOUT AN ATTACHED CRYOGENIC SECTION, OPERATED SUCCESSFULLY FOR 35,000 CYCLES (5,800 H). COMPONENT TESTING HAS SHOWN NEGLIGIBLE DEGRADATION AFTER YEARS OF SERVICE. A COMBINED CHARCOAL AND HYDRIDE REFRIGERATOR REQUIRED POWER OF ABOUT 400 W TO PRODUCE 1 W OF LIQUID HYDROGEN COOLING OR 600 W TO PRODUCE 1 W OF 10 K COOLING. POSSIBLE LONG-LIFE ADDITIONAL STAGES TO REACH 4 K INCLUDE ADIABATIC DEMAGNETIZATION REFRIGERATION, HELIUM DESORPTION, OR HELIUM COMPRESSORS WITH JOULE-THOMSON REFRIGERATION.
