摘　　要：A 50 MeV proton microbeam facility that can provide accurate irradiation dose delivery is a powerful tool in space science,biology and cancer therapy studies.However,the poor beam quality of the cyclotron and the intense scattering at the slit position are the main challenges of the 50 MeV proton microbeam system.We present the optical design for a cyclotron-based 50 MeV proton microbeam system with a micro-sized resolution.Figure 1 shows the scheme of the 50 MeV proton microbeam system.Due to the large emittance and momentum spread of the beam provided by the cyclotron.
