A superconducting wire having improved electrical and physical properties.

A superconducting wire rod according to an aspect of the present disclosure is a superconducting wire rod having a flat cross-sectional shape which is characterized in that a voltage is generated with a lower current density or a higher voltage is generated with the same current density in a region on at least one end side in a wire rod width direction as compared with a region other than the region on the at least one end side.

An interconnect may have a first end coupled to a superconducting system and a second end coupled to a non-superconducting system. The interconnect may include a superconducting element having a critical temperature. During operation of the superconducting system and the non-superconducting system, a first portion of the interconnect near the first end may have a first temperature equal to or below the critical temperature of the superconducting element, a second portion of the interconnect near the second end may have a second temperature above the critical temperature of the superconducting element, and the interconnect may further be configured to reduce a length of the second portion such that temperature substantially over an entire length of the interconnect is maintained at a temperature equal to or below the critical temperature of the superconducting element.

A superconductive wire conductor is produced by: embedding a plurality of deposition substrates formed to have a predetermined size in parallel with each other to a connection base material to connect and integrate therewith; depositing an intermediate layer, a superconductive layer and a protective layer on a deposition surface side of the deposition substrate; and winding a single or multiple integrated superconductive conductors around a desired core material, separating each single superconductive wire from the integrated superconductive conductor and winding each superconductive wire around the core material or winding the integrated or separated wire alternately, whereby a superconductive conductor having a good superconductive characteristic without a problem regarding a shape thereof such as local protrusions.

A superconducting material includes YBa.sub.2Cu.sub.3O.sub.7-? and a nano-structured, preferably nanowires, WO.sub.3 dopant in a range of from 0.01 to 3.0 wt. %, preferably 0.075 to 0.2 wt. %, based on total material weight. Methods of making the superconductor may preferably avoid solvents and pursue solid-state synthesis employing Y, Ba, and/or Cu oxides and/or carbonates.

A device for guiding charge carriers and uses of the device are proposed, wherein the charge carriers are guided by means of a magnetic field along a curved or angled main path in a two-dimensional electron gas or in a thin superconducting layer, so that a different presence density is produced at electrical connections.

High-temperature superconducting (HTS) devices and methods are disclosed. An HTS cable subassembly has a rectangular shaped cross section. The subassembly includes a stack of tapes formed of a superconducting material, and a cable subassembly wrapper wrapped around the stack of tapes. The tapes in the stack are slidably arranged in a parallel fashion. A cable assembly is formed of a cable assembly wrapper formed of a second non-superconducting material disposed around an nm array of cable subassemblies. Within a cable assembly, a first cable subassembly of the array of subassemblies is oriented substantially perpendicular to a second cable subassembly with regard to the plurality of tapes. A compound-cable assembly is formed by joining two or more cable assemblies. A high-temperature superconducting magnet is formed of a solenoidal magnet as well as dipole and quadrupole magnets wound of a cable subassembly, a cable assembly, and/or a compound cable assembly.

There is disclosed an assembly for carrying electrical current in a coil of a magnet.

A plurality of layers of HTS tape are fixed within the channel. The channel has at least one pre-formed curved section.

Quench protected structured (QPS) superconducting cables, methods of fabricating the same, and methods of bending the same are disclosed. The methods of bending the QPS superconducting cables can be employed to produce windings. The QPS superconducting cables can rapidly drive a distributed quench to a normal conducting state in a superconducting cable if a region of the cable spontaneously quenches during high current operation.
