摘要： In a method or joint for joining first and second semiconductor wires, each comprising a number of filaments which each comprise a superconductive core within a respective sheath, the filaments being embedded within a matrix and wherein the superconductive cores comprise magnesium diboride and the sheaths comprise niobium, over a certain length a matrix is removed to expose the filaments. The exposed filaments are immersed in molten tin such that the nobium of the sheaths is converted to niobium-tin throughout a thickness of the sheaths. A superconductive path is provided between the superconductive cores of filaments of the first wire through the niobium-tin sheaths of the filaments to the superconductive cores of the second wire.

The magnet structure comprises a single substantially cylindrical field coil structure comprising a number of superconducting coils joined by a support structure and extending axially of a central region. An outer vacuum chamber encloses the field coil structure in an evacuated volume. A cooling arrangement comprising cooling tubes is in thermal contact with the superconducting coils and receives a cryogen flowing through the cooling tubes. The radiation therapy equipment comprises a gamma radiation source rotatable about an axis of the field coil structure to direct a radiation beam substantially radially through the field coil structure. Parts of the field coil structure and the outer vacuum chamber are transparent to radiation emitted by the gamma radiation source whereby the radiation beam is directed through the field coil structure and the outer vacuum chamber without substantial interference.

摘要： A method for centralising and retaining a moulded end coil (20) in a magnet former (12) which includes an oversleeve (24) for retaining the end coil in position, the radially outer (A2) surface of the end coil being of lesser diameter than the radially inner surface of the oversleeve. The method comprises the steps of: (a) centralising the end coil (20) on the former (12) by passing a spigot (28) through the bore of the end coil and into the end of the bore of the former to locate the end coil within the oversleeve and to leave a gap (30) between the radially outer surface of the end coil and the oversleeve; (b) retaining the end coil in position against an axially adjacent surface of the former by applying an axial force to the end coil in the direction of the former; (c) filling the gap with a hardening material (42) along at least part of its axial length; (d) causing or allowing the hardening material to harden, thereby to securely and accurately retain the end coil onto the former; and (e) removing the spigot.
