Saddle-shaped coil winding using superconductors, and method for the production thereof

A saddle-shaped coil winding which is formed from a flat coil shape of the racetrack type on a tube outer surface, the coil winding comprising:

• axially running winding sections on longitudinal sides;
• end winding sections which run between ends of the axially running winding sections, the end winding sections forming end windings with the windings of the coil winding;
• the coil winding being formed with at least one superconductor in the form of a strip, the strip having a flat face and a narrow face, the narrow face facing the tube outer surface;
• the coil winding having a circumferential length in the saddle shape which is substantially equal to that in the flat coil shape;
• wherein the at least one superconductor is in the form of a strip and has at least two turns arranged on the tube outer surface in an area of an apex of the end winding sections, such that there is at least an inner turn and an outer turn at each end winding section;
• wherein one flat face of each superconductor strip is inclined through an inclination angle with respect to a normal of the tube outer surface in a direction of a winding center of the coil winding;
• and
• wherein an inclination angle of the outer face for the inner turn is less than an inclination angle of the outer turn.
