Isochronous cyclotron with superconducting flutter coil and non-magnetic reinforcement

摘要

An isochronous cyclotron comprises two or more superconducting coils, a magnetic yoke containing at least a portion of the beam chamber and surrounding the coil, a plurality of superconducting flutter coils on each side of the central acceleration plane, a superconducting flutter coil A non-magnetic reinforcing structure to fill the valleys between the superconducting flutter coils, an inner reinforcing structure to be mounted inside the superconducting flutter coils, and a cryocooler thermally coupled to the superconducting coils and the magnetic yokes.
