Superconductor structure and method for manufacturing same

Claim 1

A conductor structure comprising: (a) at least one inner ribbon shaped superconductor which is stabilized with normally conducting material, said superconductor extending in the longitudinal direction of said structure; (b) a jacket which consists of a reinforcement material with a mechanical strength higher than the normally conducting stabilizing material, formed by a metal sheet which is bent around said superconductor with the longitudinal edges of said metal sheet abutting and joined to each other so as to completely and immovably enclose said superconductor; (c) said sheet preprofiled so that it contains first strip like zones which extend in the longitudinal direction of the conductor and make direct contact with the superconductor and second strip like zones extending between the first zones and spaced from the surface of the superconductor, the space between said second zones and said superconductor forming channels in the interior of said structure for conducting a cooling medium in the longitudinal direction of the conductor, said first and second zones also forming channel like depressions in the outside jacket; and (d) filler strips of a thickness such that their outer flat sides, together with the outer parts of the jacket form at least approximately a smooth outer surface of the superconductor structure, disposed in and essentially filling said depressions in the outside of said jacket to form an approximately smooth outside surface for the conductor structure.

Claim 5

A method for manufacturing a superconductor structure comprising: (a) shaping an initially smooth metal sheet with a predetermined width, in a non-cutting forming operation, into a preprofiled metal sheet with longitudinally extending channel like depressions; (b) subsequently, placing said preprofiled metal sheet around a longitudinally extending ribbon shaped superconductor and closing said sheet to form a jacket, so as to form within said jacket longitudinally extending inner and outer channels extending parallel to said longitudinally extending conductors; and (c) finally, filling the outer channel like depressions of the jacket with filler strips.

Claim 6

A method for manufacturing a superconductor structure comprising: (a) shaping an initially smooth metal sheet with a predetermined width, in a non-cutting forming operation, into a preprofiled metal sheet with longitudinally extending channel like depressions; (b) subsequently, placing said preprofiled metal sheet around a longitudinally extending ribbon shaped superconductor and closing said sheet to form a jacket, so as to form within said jacket longitudinally extending inner and outer channels extending parallel to said longitudinally extending conductors; and (c) finally, filling the outer channel like depressions of the jacket with filler strips.
