Résumé

A system based on a nitrogen throttle cycle precooled by a mixed gas refrigerator was developed. It provides a temperature of 80 K needed for the specific demand of an application under discussion here (current leads between 80 K and ambient temperature level). The use of the mixed gas JT-cycle allows to achieve a high efficiency of the system. The behaviour of the refrigerator for the forced flow vapour cooled current leads was simulated and verified experimentally for varying heat loads. The paper contains the description and analysis of this system.
