Abstract: A Nb3Sn superconducting coil can be formed from a wire including multiple unreacted strands comprising tin in contact with niobium. The strands are wound into a cable, which is then heated to react the tin and niobium to form a cable comprising reacted Nb3Sn strands. The cable comprising the reacted Nb3Sn strands are then mounted in and soldered into an electrically conductive channel to form a reacted cable-in-channel of Nb3Sn strands. The cable-in-channel of reacted Nb3Sn strands are then wound to fabricate a superconducting coil. The Nb3Sn superconducting coil can be used, for example, in a magnet structure for particle acceleration. In one example, the superconducting coil is used in a high-field superconducting synchrocyclotron.

Abstract: A new class of fundamental devices and methods for their manufacture and use. The bulk magnetic field replicators of the present invention require no precision machining or alignment to accurately reproduce magnetic fields of any complexity, nor extreme positional stability to maintain superconductivity. Such bulk devices may be formed of either low or high critical temperature superconductive materials, but are particularly adapted to formation from high critical temperature materials.

Abstract: Disclosed is a saddle-shaped coil winding which is formed onto an outer tube surface from a planar race track-type coil shape so as to be provided with axially extending winding sections on the longitudinal side and winding sections that extend therebetween, are located on the front side, and form winding overhangs. The individual windings of the coil winding are to be formed with at least one band-shaped superconductor which comprises especially high Tc superconductor material and whose narrow side faces the outer tube surface. In order to prevent unacceptable mechanical stresses of the conductor when forming the coil, the windings in the saddle shape have a circumferential length which is virtually unchanged from the length in the planar oil shape.

Abstract: A method of manufacturing a radially oriented magnet comprises disposing magnetic particles in a mold comprised of an insulating material, applying a pulsed magnetic field to the magnetic particles using a pair of pulse coils to impart a radial direction of magnetization to the magnetic particles, and press-forming the magnetic particles. The effective amount of magnetic flux which is applied to the magnetic particles can be effectively increased by introducing a pair of conducting rings between the pair of pulse coils for generating an eddy current effect between the pair of pulse coils to control the magnetic flux of the pulsed magnetic field. Such a method enables the manufacture of a downsized radially oriented magnet having a high degree of orientation.
