First Claim
1. In a magnetic device arranged in a curved section of a path of electrically charged particles in an accelerator installation, said magnetic device being arranged around a beam guiding chamber and having superconducting, curved coil windings, said coil windings having convex outsides, concave insides and transition areas at the coil ends between said convex outsides and concave insides, and said coil windings comprising superconducting rectangular conductors, an improvement wherein said superconducting coil windings, at least with said convex outsides and concave insides, form winding parts arranged in grooves of correspondingly formed coil formers, said grooves extending approximately perpendicular to a plane defined by said particle path, and, further, wherein said superconducting coil windings, in the transition areas of said coil ends, are bent up saddle-shaped.

Abstract
A magnetic device is arranged in a curved section of the path of electrically charged particles of an acceleration installation around a beam guiding chamber. The magnetic device contains curved coil windings built up of superconducting rectangular conductors, which have convex outsides, concave insides as well as transition regions at the coil ends between these sides. The superconducting coil windings (4a) according to the invention are arranged at least with their winding parts (57, 58) forming the convex outsides (53) and concave insides (54) in grooves of correspondingly formed coil formers of the magnetic device, with the grooves extending downward at least approximately perpendicular to the plane (x-y plane) determined by the particle path. In addition, the superconducting coil windings (4a'"'"') in the region of their coil ends (55'"'"') are bent up saddle-shaped. With these measures the effect of undesirable conductor motions on the exactitude of the magnetic fields generated by the coil windings can at least largely be excluded.
