A method for forming a plurality of filaments, such that each filament is superconducting. The method includes providing a substrate having first and second sides. The substrate has a plurality of grooves in the first side of the substrate having a coating of a superconducting material so that for each groove within the plurality of grooves. A first part of the coating on a first side of a feature of the groove is separated from a second part of the coating on a second side of the feature of the groove. The second side of the feature of the groove is opposite of the first side of the groove, with removing from the second side of the substrate, at least a part of the substrate, to remove at least a connection from the first part of the coating to the second part of the coating via the substrate.

A hybrid cable generally comprising a superconducting material and a material consisting at least partially of a conventional conductor. In operation, the hybrid cable is chilled to superconducting temperatures, wherein current primarily passes through the superconducting material. If the superconducting material loses performance, e.g., is quenched, current will flow primarily through the chilled conventional conductor. In the event hybrid cable temperature further increases, the current will travel through the conventional conductor at its normal capacity.

A conformal dipole winding includes a superconducting tape configured with a geometry that orients a face of the superconducting tape to be parallel to a local magnetic field produced by the winding along a length of the superconducting tape. The superconducting tape forms a tape-stack cable formed from a stack of a plurality of the superconducting tapes. A face of each of the superconducting tapes is oriented parallel to the local magnetic field and is in face-face contact with adjacent superconducting tapes.
