Title Superconducting Dipole Design for a Proton Computed Tomography Gantry
Contributors
Abstract Proton computed tomography aims to increase the accuracy of proton treatment planning by directly measuring proton stopping power. This imaging technique requires a proton beam of 330 MeV incident kinetic energy for adult patients. Employing superconducting technology in the beam delivery system allows it to be of comparable size to a conventional proton therapy gantry. A superconducting bending magnet design for a proton computed tomography gantry is proposed in this paper. The 30 deg, 3.9 T canted-cosine-theta dipole wound with NbTi wires is used to steer 330 MeV protons in an isocentric beam delivery system which rotates around the patient. Two methods of magnetic field shielding are compared in the context of proton therapy facility requirements; traditional passive shielding with an iron yoke placed around the magnet and an active shielding option utilising extra layers of the superconducting coil.
