Abstract：
Taking into account of inelastic scattering process, such as ionization, excitation et al., a Monte Carlo track structure model of the proton and α particle in water has been described. In the simulation, the energy range of proton and α particle is about 0.3—5MeV/u. The cutoff energy of secondary energy electron is taken as 1eV. Tracks were analyzed to provide confirmation on the reliability of the code and the information on physical parameters, such as range, radial dose profiles. Our Model calculation shows the good agreement with the experimental data.
