A New Refrigeration System for 4.2°K
A year ago, a new refrigeration cycle was described [1,2]. Its basic simplicity showed promise of excellent reliability and ease of construction. It was able to reach 35°K and to generate refrigeration efficiently at 80°K and above in its most elementary form. The purpose of this paper is to show how the basic method with modifications can be used as the base for a small, simple helium-temperature refrigerator and to describe such an operating refrigerator.
