Document Type and Number:
Japanese Patent JP2555132
Kind Code:
B2
Abstract:
PURPOSE:To provide a field winding capable of generating magnetic field highly uniformly by removably mounting ribs on the surface of a torque tube for defining parallel grooves extending in the axial direction, and disposing a compound superconductor winding in the grooves. CONSTITUTION:Rib pairs 11 and 12, 21 and 22,...81 and 82 are provided on a torque tube 90 having projections extended longitudinally and spaced circumferentially by 90 deg.. These ribs are attached to the torque tube 90 by mechanically bolting the same, by welding or by means of a binder, so that a groove is formed therebetween. Winding is previously heat-treated by diffusion having the same configurations as those of the grooves in which the winding is to be disposed. The winding may be impregnated with epoxy resin if required. The winding contains a compound superconducting body. In order to arrange the winding on the torque tube 90, the winding is first disposed on the projections extending in the direction X and then the ribs 41 and 42 are fixed. The winding is disposed on the opposite side of the tube and the ribs 51 and 52 are fixed. In the same way, disposition of the winding and fixation of the ribs are repeated also in the direction Y. Finally, the winding is disposed and the ribs 11 and 12, 81 and 82 with wedge-like profile are fixed to complete a field winding.
