Magnetic field device for a system for the acceleration and/or storage of electrically charged particles
First Claim
1. A magnetic-field device for a system for at least one of the acceleration and storage of electrically charged particles, particularly electrons, the particle trajectory of which has curved sections, and having an appropriately curved dipole magnet having a concave section and a convex section, the dipole magnet comprising superconducting windings for generating a magnetic guiding field for the particle beam which has a weakly focusing effect due to field gradients thereof, each dipole magnet being at least largely free of iron and having associated therewith a superconducting supplemental winding, said superconducting supplemental winding being curved to match said superconducting windings of said dipole magnet, and having a convex section which adjoins a region of the concave sections of the curved windings of the dipole magnet, whereby the required field gradients can substantially be generated.

Abstract
A magnetic field device for a system for acceleration and/or storage of electrically charged particles, particularly electrons, comprises curved sections in the particle trajectory, in which an accordingly curved dipole magnet is arranged, which contains superconducting windings and a supplemental winding and with which a magnetic guidance field for the particle beam can be generated which has a weakly focusing effect due to corresponding field gradients. It should be possible to bring about these field gradients in a relatively simple manner also for a high magnetic flux density. Accordingly, it is provided for this purpose that with each dipole magnet which is at least free of iron, a superconducting supplemental winding is associated which is curved accordingly, adjoins at least with its convex outside the region of the concave inside of the curved dipole windings, and with which the necessary field gradients can be brought about in substance.
