Abstract
A new sub-Kelvin refrigerator, the superfluid Stirling cycle refrigera tor, uses a working fluid of He-3-He-4 mixture in a Stirling cycle. Th e thermodynamically active components of the mixture are the He-3, whi ch behaves like a Boltzmann gas, and the phonon-roton gas in the He-4. The superfluid component of the liquid is inert. Two refrigerators ha ve been built, and temperatures of 340 mK have been achieved.
