A superconducting coil device includes a superconducting flat conductor having one or more torsional turns. The flat conductor is wound around a winding support to define multiple turns of the conductor around the support. In at least one of the turns, the flat conductor is twisted through approximately 180 degrees about a longitudinal axis of the flat conductor, to thereby switch a contact side of the flat conductor from radially inwardly facing to radially outwardly facing, or vice versa. The contact side of the flat conductor at an inner turn faces a center of the winding and, and at an outer turn faces away from the center of the winding. The inwardly-facing contact side of the strip at an inner turn may be coupled to an inner contact element, and the outwardly-facing contact side at an outer turn may be conductively coupled to an outer contact element.

Superconducting coil device with coil winding and production method

In a coil device with at least one electrical coil winding with superconducting conductor material, the coil winding is part of a self-contained circuit for formation of a continuous current. The closed circuit has a switchable conductor section which can be switched between a superconducting state and a normally conducting state by a magnetic device.
