Abstract

An isochronous cyclotron including one or more coils and a plurality of pairs of bulk superconductor sectors. The one or more coils can be configured to generate a magnetic field in the beam chamber having a magnetic flux density that increases radially from the central axis of the beam chamber, and is orientated substantially perpendicular to the median acceleration plane of the beam chamber. Each pair of bulk superconductor sectors can be disposed on opposite sides of the median acceleration plane. The plurality of pairs of bulk superconductor sectors can be configured to guide or concentrate the magnetic field to provide an axial focusing component of the magnetic field.
