  • Publication number: 20020101239
    Abstract: A magnet arrangement comprising an actively shielded superconducting magnet coil system (M) and a plurality of protective elements (R1, . . . , Rl) for protection in case of a quench, wherein the superconducting magnet coil system (M) comprises a radially inner partial coil system (C1) and a radially outer partial coil system (C2) which are electrically connected in series and arranged coaxially with respect to one another and which each produce a magnetic field of opposite direction, wherein the superconducting current path of the magnet coil system (M) is subdivided into several sections (A1, . . . , An) each of which is electrically connected in parallel with at least one of the protective elements (R1, . . . , Rl), and wherein at least one of these sections (A1, . . .

  • Publication number: 20020047763
    Abstract: A superconducting magnet arrangement (M, S, P1, . . . , Pn) for generating a magnetic field in the direction of a z axis in a working volume, disposed about z=0, comprising a magnet coil system (M) with at least one current-carrying superconducting magnet coil, a shim device (S) with at least one superconducting shim coil and additional superconductingly closed current paths (P1, . . . , Pn), wherein the magnetic fields generated in the z direction and in the working volume by the additional current paths due to induced currents during operation, do not exceed a magnitude of 0.1 Tesla, and wherein the shim device generates a field which varies along the z axis with a kth power of z for an even power of k>0. is characterized in that the shim device is designed such that the effective field efficiency gSeff of the shim device is substantially zero taking into consideration the diamagnetism of the superconductor in the magnet coil system.

  • Publication number: 20020044034
    Abstract: A superconducting magnet system for generating a magnetic field in the direction of a z axis in a working volume disposed about z=0 with at least one current-carrying magnet coil (M) and with at least one additional, superconductingly closed current path (P1, . . . , Pn), which can react inductively to the changes of the magnetic flux through the area enclosed by it, wherein the magnetic fields in the z direction in the working volume which are produced by these additional current paths during operation and due to induced currents, do not exceed a magnitude of 0.1 Tesla, is characterized in that, when an additional disturbance coil (D) produces a substantially homogeneous disturbance field in the magnet volume, the diamagnetic expulsion of the disturbance field from the main magnet coil is taken into consideration when designing the magnet coil(s) and the current paths.
