ABSTRACT:
A high temperature superconductor lead assembly for reduces the heat leak into a cryocooled magnet system includes a superconductor and a first lead connector bonded to a first end of the superconductor. The lead connector includes an electrically insulating, thermally conductive ceramic mount for attachment to a mechanical cryocooler for cooling the connector. The superconductor is in the form of a stack of ribbons. The superconductor is attached to an electrically and thermally insulating support. A cryocooled magnet system includes a mechanical cryocooler having a warm end and a cold end, a superconductor magnet maintained at a temperature of the cold end of the cryocooler, two superconductor leads, and two current carrying leads for supplying power to the superconductor leads.
