ABSTRACT:
A thermal plug which provides an electrical connection between first and second regions at different temperatures includes a plurality of interleaved heat transfer resistive laminae and heat conductive laminae. The laminae are stacked together to form a laminate and a plurality of superconducting strands are attached to the stack such that they are in thermal contact with the laminate. The superconducting strands are also in electrical contact with a conductor (e.g., a low temperature superconductor), in the first region and a conductor in the second region to allow the supply and withdrawal of electrical energy to and from the conductor in the first region.
