Summary:

Consideration is given to the use of a hydrogen refrigerator to assist in the production of temperatures below those obtained with hydrogen. A hydrogen refrigerator is used to maintain a precooling evaporator at or near 21° K in a helium gas circuit. The helium circuit may be arranged to produce liquid for external use or to produce refrigeration between 21° K and 4.2° K in a closed system. Charts have been developed that show the requirements of the composite helium: hydrogen system and the effect of heat exchanger performance. The relative quantities of refrigeration (hydrogen and helium) at various temperature levels have been determined.
