The proton beam with the energy of 30 MeV to 50 MeV and the current of 10 uA will be extracted by a single stripping extraction system. In order to reduce the beam loss, the combination magnet is fixed inside the magnetism yoke. The positions of stripping points for the different extraction energy are calculated and the extracted beam trajectories after stripping foil are simulated in detail in this paper. The extracted beam distribution after stripping foil and the extracted beam characters will be studied in this paper. The beam parameters after extraction will be given by the extracting orbit simulation. The design on the whole stripping extraction system has been finished and will be presented in this paper.
