Research on Secondary Electron Emission Characteristics of Metal Materials based on Monte-Carlo Simulation

With the rapid development of astronautics, various types of spacecrafts have been widely used. However, the secondary electron multiplication effect can affect the stability of the spacecraft. To solve this problem, it is necessary to study the secondary electron emission characteristics of metal materials. In this paper, the emission characteristics of secondary electrons, and the physical process of secondary electron radiation are introduced, and an elastic scattering cross-section model represented by mott cross-section and a model based on Penn dielectric function theory is established. The Monte Carlo method is the most common method in this field, on the basis of drawing a diagram, the effect of the incidence angle, sample material, and other factors on the secondary electron emission yield are analyzed, and finally, the correctness of the Monte Carlo method in this paper is verified by the comparison of simulation data and experimental data.
