Abstract
A refrigeration process is described which enables the production of a sub‐λ‐point 4He temperatures without the production of superfluid. The advantages of the process for zero gravity (0‐g) and low‐noise refrigeration are described. The lowest temperature produced to date is 1.25 K. The process is also useful with other gases for refrigeration; the output temperature is selected by gas type.Keywords
