Part of the Advances in Cryogenic Engineering book series (ACRE, volume 23)


The growing importance of potential applications of large superconducting magnets focuses attention on the need for highly efficient helium refrigeration and liquefaction systems. This thermodynamic optimization study was intended to provide cycle guidelines for large refrigerators operating between 300 and 4.2 K. Systems studied ranged from the basic Claude cycle with one expander, to refrigerators with six expansion engines, with calculations made for both Joule-Thomson (J-T) and wet expansion in the final stage.
