Abstract, In a proton/neutron source incorporating a cyclotron in, particular a superconducting cyclotron having a cylindrical superconducting magnet incorporating superconducting magnetic coils associated with pole pieces, a stream of ionized particles, such as H-particles, is continuously injected into the center of the cyclotron beam space and is accelerated outwards in a spiral path under the combined effect of the magnetic field from the superconducting magnet and RF, energization applied to sector-shaped electrodes. When the particles reach the required energy, they are removed from the spiral path by septa electrodes, and are passed across a proton storage ring in a path of rapidly …
