A Recuperative Superfluid Stirling Refrigerator
A superfluid Stirling refrigerator has been built with a counterflow heat exchanger serving as a recuperative regenerator. It has achieved temperatures of 296 mK with a 4% 3He-4He mixture. Cooling power versus temperature and speed is presented for a 6.6% mixture.
