  The superconducting cyclotron SC200 for proton therapy is designing by ASIPP (Hefei, China) and JINR (Dubna, Russia) will be able to accelerate protons to the energy 200 MeV with the maximum beam current of 1 mkA. By computer simulation with 3D codes the cyclotron magnet principal parameters were estimated (pole radius 0.62 m, outer diameter 2.2 m, valley depth 0.3 m, height 1.22 m, weight ~30 t). The required isochronous magnetic field is shaped with accuracy some mT. Four fold symmetry and spiralized sectors with minimal gap 4 mm at extraction provide the stable beam acceleration till 10 mm from the pole edge.
