	The SC200 is a compact superconducting cyclotron, which is designed under the collaboration of ASIPP (Hefei, China)-JINR (Dubna, Russia), for proton therapy. The protons are accelerated to 200 Mev with maximum beam current of 500 nA. The very high mean magnetic field of 2.9T-3.5T (center-extraction) challenges the design of radio frequency (RF) system because of the restricted space. The orbital frequency of the protons is ~45 MHz according to the magnetic field and beam dynamics. The RF system is supposed to operate on 2rd harmonic of ~90 MHz. Two Dee cavities located at the valley of the magnet have been adopted. The preliminary design of RF system, which consists of active tuning, coupling and so on, is presented. The computation and simulation showed good results to ensure the Dee cavities operating at the 2rd harmonic and the proper variation of acceleration voltage versus radius.

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 μA. A conceptual design study with 3D codes for the superconducting cyclotron magnet has been carried out during 2015-16 at ASIPP and JINR. The main design considerations are reviewed. The results obtained by numerical field computation for a suitable choice of design parameters are presented. Results of numerical calculations are the basis for technical design of SC200 cyclotron.
