Résumé

This paper describes the progress towards a single-stage, low power (lower than 1 W) mixed gas Joule-Thomson (MGJT) cryocooler for cooling the current leads required by superconducting electronics. By thermally integrating the leads with the recuperative heat exchanger in the MGJT cycle, it is possible to intercept the electrical dissipation and conductive heat leak of the wires at a relatively high temperature thereby providing a thermodynamic advantage. Also, cooling the leads instead of the cryogenic platform may provide some advantages relative to thermal integration.
