A composition comprises one or more continuous fibers embedded in a high temperature superconducting material.

A structure and method provide cables of high-temperature superconducting flat tape and/or filament wires, with a small bending diameter. A cable has a former having cross section that includes a rectangle having rounded ends (i.e. an obround), and the flat tape is wound around the surface of the former at an angle to minimize bending. The former surface may have raised helical ribs or lowered grooves to provide tape registration in multi-layer configurations. Tape may be wound from a spool onto the former under tension, and cut with a laser cutter to produce fine filaments immediately before winding. The former may be slit longitudinally to prevent loop eddy currents and reduce AC losses. The wound cable may be jacketed to provide a cable-in-conduit conductor (CICC), and coolant channels may be provided in the jacket or in the former.

The present disclosure provides a circuit that includes a first component and a plurality of superconducting wires thermally-coupled to the first component. The superconducting wires of the plurality of superconducting wires are arranged and configured such that a threshold superconducting current for each superconducting wire is dependent on an amount of heat received from the first component. The circuit further includes a dielectric material separating the plurality of superconducting wires from one another. A superconducting wire nearest the first component among the plurality of superconducting wires is more than a phonon mean free path of the dielectric material from the first component. The circuit further includes control circuitry electrically-coupled to the plurality of superconducting wires and configured to provide current to each of the plurality of superconducting wires.
