The SC200 superconducting cyclotron for proton therapy is under development by collaboration of Hefei government of China and the institute of plasma physics, Chinese academy of sciences. A fixed energy 200 MeV proton beam with maximum current of 1 μA will be extracted from cyclotron in 2018. The compactness of line, the large 90 degree bending magnet at the end of the gantry, and the degrader is usually causing some problems in this field. We have performed simulations of all the beam line of the SC200 cyclotron and specified the main parameters of the line, such as the emittance after degrader and collimator and the maximum gradient of quadrupole magnet field. On the medical request, we defined the proton channel and several beam lines to special therapy demands. In addition, we maintain mathematical tools for simulations of beam line, degrader, collimator and scanning magnet.
