Abstract
A compact, cold, superconducting isochronous cyclotron can include at least two superconducting coils on opposite sides of a median acceleration plane. A magnetic yoke surrounds the coils and a portion of a beam chamber in which ions are accelerated. A cryogenic refrigerator is thermally coupled both with the superconducting coils and with the magnetic yoke. The superconducting isochronous cyclotron also includes sector pole tips that provide strong focusing; the sector pole tips can have a spiral configuration and can be formed of a rare earth magnet. The sector pole tips can also be separated from the rest of the yoke by a non-magnetic material. In other embodiments, the sector pole tips can include a superconducting material. The spiral pole tips can also include cut-outs on a back side of the sector pole tips remote from the median acceleration plane.
