Operation and Application of a Three-Stage Closed-Cycle Regenerative Refrigerator in the 6.5°K Region
The general methods for obtaining low-temperature refrigeration under laboratory conditions are: boil-off of a bath of liquefied gas such as helium, closed-cycle refrigeration employing expansion engines alone, and closed-cycle refrigeration employing a Joule-Thomson expansion loop tied thermally to an expansion engine cycle for precooling.
