A cylindrical superconducting coil assembly has multiple individual coil units stacked together and retained in place by retaining structures, each coil unit having a resin-impregnated annular superconducting coil bonded at its axial extremities to respective rings of non-ferromagnetic material.

Method of constructing a cylindrical superconducting magnet coil assembly

A superconducting magnet coil arrangement has multiple superconducting coils and at least one of the superconducting coils is provided with a secondary coil of insulated resistive wire mechanically attached to a surface of the superconducting coil.

Superconducting magnet coil arrangement

In an MRI magnet structure for use with a radiation beam source as an assembly, magnet coils of varying diameters are concentrically arranged along a magnetic axis, the magnetic coils not sharing a common inner or outer radius. Mechanical support is provided to retain the magnetic coils in necessary relative fixed positions. The patient bore tube is provided through the assembly and defines a patient bore axis in an essentially horizontal direction such that the magnetic axis is inclined to the patient bore axis by an angle of 30&#xb0;-60&#xb0;. At least one radiation therapy beam access cavity provides access in a straight line for a radiation therapy beam to reach a treatment region within the magnet structure.

MRI magnet for radiation and particle therapy

In a solenoid magnet assembly, and a method for manufacture thereof, the magnet assembly includes a number of concentrically aligned coils, each including a winding impregnated with a resin. Each coil is mechanically restrained so as to hold the coils in fixed relative positions relative to each other when forming the magnet assembly. The mechanical restraint can be formed by annular support sections bonded to the respective coils, lugs bonded to the respective coils, or by lugs that are at least partially embedded in a crust formed on a radially outer surface of the respective windings.

Adhesively bonded cylindrical magnets comprising annular coils, and method of manufacture thereof

An arrangement for supporting a cylindrical superconducting coil structure has recesses in an axial end-surface of the coil structure, and support brackets that individually horizontally protrude into the recesses, such that a vertical loading on the support brackets bears the weight of the coil structure. Opposite ends of the support brackets engage a support member, which supports the support brackets engaged therein, thereby also bearing the weight of the coil structure.

Method for constructing a solenoidal magnet assembly

A superconducting electromagnet comprising coils of superconducting wire bonded to a support structure, and wherein heating elements are provided in thermal contact with the support structure for heating the support structure.
