	A 100 MeV H⁻ compact cyclotron is under construction at China Institute of Atomic Energy (CYCIAE-100). The proton beams of 75 MeV - 100 MeV at an intensity of 200 μA will be extracted in dual opposite directions by charge exchange stripping devices. The two main parameters for the stripping extraction are the positions of stripping foil and combination magnet. For CYCIAE-100, the center of combination magnet is fixed at (R=2.75 m, θ=100°) and the extracted radii decide the positions of stripping foil for different extracted energies. In order to analyze the extracted proton beam parameters, the stripping extraction process for CYCIAE-100 is simulated in detail in this paper. The simulation is mainly done for the different RF acceptance or acceleration phase width. The simulation results indicate that the energy spreads of the extracted beams under different initial phase width conditions are almost the same. The transverse beam distribution and the extracted beam profile are not affected by the initial phase width due to the simulation, that's the characters of the cyclotron with the stripping extraction mode.

A 100 MeV H⁻ compact cyclotron is under construction at China Institute of Atomic Energy (CYCIAE-100). The proton beams of 75 MeV - 100 MeV at an intensity of 200 μA will be extracted in dual opposite directions by charge exchange stripping devices. The two main parameters for the stripping extraction are the positions of stripping foil and combination magnet. For CYCIAE-100, the center of combination magnet is fixed at (R=2.75 m, θ=100°) and the extracted radii decide the positions of stripping foil for different extracted energies. In order to analyze the extracted proton beam parameters, the stripping extraction process for CYCIAE-100 is simulated in detail in this paper. The simulation is mainly done for the different RF acceptance or acceleration phase width. The simulation results indicate that the energy spreads of the extracted beams under different initial phase width conditions are almost the same. The transverse beam distribution and the extracted beam profile are not affected by the initial phase width due to the simulation, that's the characters of the cyclotron with the stripping extraction mode.
