Abstract :
A superconducting strong focusing cyclotron (SFC) is being developed for high current applications. The dipole magnetic field required for isochronous operation is provided by sector magnets utilizing a common warm-iron flux return and levitated cold-iron pole design. The sector magnets utilize MgB2 superconducting cable operating at 15-20 K. The sector dipoles for a 100 MeV SFC were modeled to provide for isochronous operation. The field distribution, fringe fields, forces and torques in the dipole were calculated.
