This report summarizes work done on the development of a low-noise Joule-Thomson, microminiature refrigeration system designed for 10 K operation. Topics discussed include: calculation of phase diagram of mixtures of certain hydrocarbon gases with nitrogen using the Benedict-Webb-Rubin equation of state; the setup of a magnetron-enhanced sputtering system to allow sputtering a layer of adhesive on the glass substrates with a much-better-defined thickness than can be laid down using the older screen printing method; redesign of H/sub 2/ refrigerator test stage, redesign of mixed-gas heat exchanger, refrigerator fabrication, and gas cleaner.
