Abstract: A composite billet includes an array of textured-powder bars in a geometry that is compatible with assembly and drawing of a billet with LAR˜1:1. A method is presented of compressing the bars suitable for the billet geometry in an inert gas environment. Methods of drawing of the billet control the deformation of the composite billet during area-reducing draw to fine wire so that the shape and registration of the constituent bars is preserved. Lastly a method is disclosed to fabricate a cable-in-conduit conductor containing the textured-powder Bi-2212/Ag wires that enables robust forming of windings and also provides in-cable containment of a buffer gas flow under high pressure during the high-temperature heat treatment of the winding that is required to produce optimum superconducting performance in the winding.

Abstract: A design is presented for a structured cable suitable for carrying a large electric current in a cable-in-conduit comprising an assembly of rectangular stacks of thin superconducting tapes, with provisions for mechanical support of large mechanical stress and cross-flow of cooling fluid capable of removing large amounts of heat.

Abstract: 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.
