Abstract
Abstract A superconductor is provided as a tube made from a selfsupporting thin sheet with axial welding seam and attached to a separately made carrier, either as an outside envelope or, in case of a tubular carrier, as an inside lining, but always in intimate contact with the respective cylindrical carrier surface.

Claim 1
Independent Claim
71 words
The method of making a superconductive arrangement, comprising: providing a thin tape of superconductive material as a self supporting foil, and having thickness in the range of 0.03mm to 0.5mm; bending the tape longitudinally into tubular configuration to obtain axially adjoining edges; welding the edges to obtain an axial seam; and extruding a plastic material as carrier onto the tubular configuration so that the interiOr of the tubular configuration remains empty.
