  • Patent number: 7330092
    Abstract: A superconducting magnet coil configuration comprising at least one section of a superconducting strip conductor, which is continuously wound in a cylindrical winding chamber (1) between two end flanges (2, 3) in several solenoid-like layers is characterized in that the section comprises an axial region of reduced current density (=notch region (12)), and the winding chamber (1) in the notch region (12) contains a first separating body (4) with a truncated conical envelope (5) which axially divides the winding chamber (1) into two partial chambers (6, 7), the superconducting strip conductor being guided over the truncated conical envelope (5) of the first separating body (4) from one partial chamber (6) into the other partial chamber (7) via a single-layer transfer winding (9), and a second separating body (10) is provided which supplements the first separating body (4) in the notch region (12) in a radial outer direction to form a circular cylinder, wherein the single-layer transfer winding (9) is disposed b

  • Patent number: 7317369
    Abstract: A superconducting magnet coil configuration comprising at least one section of a superconducting strip conductor, which is continuously wound in a cylindrical winding chamber (1) between two end flanges (2, 3) in several solenoid-like layers is characterized in that the section comprises an axial region of reduced current density (=notch region (10)), and the winding layers (6, 9) have hollow cylindrical blind regions (4a, 4b, 4c) which are filled with filler and which have different axial lengths, and radially sequential blind regions (4a, 4b, 4c) each alternately abut one of the two end flanges (2, 3) and are each radially separated from each other by at least one continuous winding layer (7), wherein the axial overlapping region of the blind regions (4a, 4b, 4c) forms the notch region (10). The inventive device thereby realizes a magnet coil configuration comprising a strip conductor which has a notch region for correcting inhomogeneities, wherein the mechanical load on the strip conductor is minimized.

  • Patent number: 7310034
    Abstract: A superconducting magnet coil configuration has at least one section containing a superconducting strip conductor which is wound in several layers like a solenoid in a cylindrical winding chamber (1) between two end flanges (2, 3), characterized in that the radially innermost layers of the section consist of metallic low-temperature superconductors (LTS) (LTS layers (8)) and radially adjacent layers of the section are formed from high-temperature superconductor (HTS) material (HTS layers (9)). The invention proposes a magnet coil configuration using HTS material which has a notch structure for correcting inhomogeneities and homogenizing a compact high-field magnet, wherein the mechanical load on the HTS strip conductor is minimized.

  • Patent number: 7215230
    Abstract: A method for calculating the shape of a band-shaped superconductor (3) of a solenoid-shaped coil section of a high-field magnet coil (1) in a transfer region (5) is characterized in that the band-shaped superconductor (3) is changed in the transfer region from a first orientation (3a) tangentially flatly abutting on the surface of a cylindrical coil body (2) and substantially perpendicular to the longitudinal direction of the cylindrical coil body (2) to a second orientation (3b) with its narrow side seating on the surface of the cylindrical coil body and parallel to the longitudinal direction (or vice versa).
