Korea Institute of Radiological & Medical Sciences (KIRAMS) has started the development of a superconducting cyclotron for carbon therapy. The goal of the development is to produce a 430 MeV/u carbon beam for medical use. The magnet system is composed of one set of NbTi superconducting coils and four spiral sectors with a return yoke. The hill angular widths, hill gaps, and spiral angles with radius have been designed for the isochronous magnetic field. The spiral sector shape and the beam characteristics of the designed magnetic field have been presented.
