Abstract

A superconducting coil device includes at least one coil winding, including at least one first and one second superconducting strip conductor, the first and second strip conductors each having a superconducting layer and a contact side provided with a contact layer; at least one first contact electrically connecting the contact side of the first strip conductor to an external circuit via a first contact piece; at least one second contact electrically connecting the contact side of the second strip conductor to the external circuit via a second contact piece; and a third contact electrically connecting the first and second strip conductors via the contact layer of the first and the second strip conductor within the coil winding, wherein the contact side of the first strip conductor has a different orientation relative to a center of the coil winding than the contact side of second strip conductor.
