Abstract
A lead interface for a superconducting device has a segment of normal conducting lead electrically connected to a segment of superconducting lead coiled within a dewar. The superconducting lead is adapted to be cooled to below the superconductor critical temperature by circulating a cooling fluid through an internal fluid chamber which runs the length of the superconducting coil and into an intermediate disk having an internal spiral fluid chamber. When the superconducting device is on standby, a superconducting switch is closed and the superconducting segment of the interface is left uncooled. To charge or discharge the superconducting device, the superconducting segment of the interface is cooled prior to opening the superconducting switch.
