A method for creating electrical contact between a first superconductive strip conductor and a further electrical conductor element, wherein the first superconductive strip conductor is placed in flat contact against a first main surface of a reactive multilayer film in a contact area of the strip conductor, the second main surface, facing away from the first main surface, of the reactive multilayer film is placed in flat contact against the further electrical conductor element, and a permanent electrically conductive connection is formed between the first superconductive strip conductor and the further electrical conductor element by subsequently igniting an exothermic chemical reaction in the multilayer film. An electrical conductor assembly is able to be contacted using such a method.

Method for making electrical contact with a superconductive strip conductor

A method for producing an electrical coil device may include winding a strip conductor into a coil winding and subsequently dividing the coil winding into at least two partial coils by at least one cut through the coil winding, wherein the strip conductor remains connected as a doubly contiguous loop by existing remaining connections in the end regions of the strip conductor. An electric coil device is also disclosed, which includes at least two partial coils from a higher-level doubly contiguous strip conductor. The at least two partial coils may be produced by subsequent cutting of a coil winding wound by a single strip conductor.

Forming an electrical coil device by cutting a strip conductor winding into at least two partial coils

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

An electric coil apparatus has at least two subcoils from a superordinate doubly connected tape conductor. The coil apparatus has at least two conductor branches, each of the subcoils being wound from one of these conductor branches respectively. The conductor branches of the superordinate tape conductor have a superordinate first surface and a superordinate second surface facing away from this first surface. In a first subcoil, the first surface of the tape conductor faces a centerpoint of the first subcoil, and in a second subcoil, the second surface of the tape conductor faces a centerpoint of the second subcoil. Furthermore, in a manufacturing method of such a coil apparatus the two conductor branches are routed parallel to each other so as to dorm the subcoils.
