Abstract: An example particle therapy system includes: a synchrocyclotron, and a gantry on which the synchrocyclotron is mounted to rotate around a patient position to position the synchrocyclotron relative to a treatment area of the patient. The synchrocyclotron includes a magnet having a coil to receive electrical current and to generate a magnetic field in response to the electrical current. The magnetic field causes the particles to move orbitally within a cavity at an energy that corresponds to the electrical current, and the coil includes multiple integrated conductors that are wound together. An integrated conductor includes: a core including conductive or superconducting material; and at least six strands wound around the core, with each of the at least six strands including a superconducting material. The synchrocyclotron includes an extraction channel to receive the particles from the cavity and to output the particles received from the cavity.

Abstract: A superconducting magnetic coil includes a plurality of sections positioned axially along the longitudinal axis of the coil, each section being formed of an anisotropic high temperature superconductor material wound about a longitudinal axis of the coil and having an associated critical current value that is dependent on the orientation of the magnetic field of the coil. The cross section of the superconductor, or the type of superconductor material, at sections along the axial and radial axes of the coil are changed to provide an increased critical current at those regions where the magnetic field is oriented more perpendicularly to the conductor plane, to thereby increase the critical current at these regions and to maintain an overall higher critical current of the coil.
