A superconducting structure () has a plurality of coated conductor tapes (-), each with a substrate () which is one-sided coated with a superconducting film (), in particular an YBCO film, wherein the superconducting structure () provides a superconducting current path along an extension direction (z) of the superconducting structure (), wherein the coated conductor tapes (-) provide electrically parallel partial superconducting current paths in the extension direction (z) of the superconducting structure (), is characterized in that the coated conductor tapes (-) are superconductively connected among themselves along the extension direction (z) continuously or intermittently. A more stable superconducting structure with which high electric current strengths may be transported is thereby provided.

A method for superconductingly connecting two or more wires (), each comprising at least one filament (-) that contains MgBor a mixture of Mg and B, wherein a superconducting connection is realized through exposed end regions () of the filaments (-) via an MgBmatrix, is characterized in that a bulk boron powder () is provided into which the exposed end regions () of the filaments (-) of the wires () project, the boron of the bulk boron powder () being present in amorphous modification. The bulk powder () is then compacted together with the projecting exposed end regions () of the filaments () to form a compressed element () and the compressed element () is infiltrated with molten magnesium () from the surface () of the compressed element (). The method improves the quality, in particular, the current-carrying capacity and the critical magnetic field strength of a superconducting connection of MgBsuperconducting wires.

A current lead () for connecting a superconducting load system (), in particular, a magnet coil, to a current feed point () that is at a higher temperature than the load system () comprises a flat, elongated carrier () and a plurality of mechanical and electrical parallel high-temperature superconductors (HTSC) (), wherein the HTSCs () are disposed side by side on the carrier (). The carrier () is made of stainless steel, and a plurality of HTSCs () are each disposed side by side on two opposite carrier () sides of the carrier. The carrier () is constituted in the shape of a plate with cut-outs (-). The current lead has a high current capacity and low thermal conductivity and provides improved emergency conduction properties in case of failure of the superconductivity in the HTSC.
