Abstract
In order to study the process of high energy proton passing through a thin film, a non-equilibrium statistical model of proton irradiation was established on the basis of stochastic theory. Considering the statistical model and the electronic stopping power, the Langevin equation and the corresponding Fokker–Planck equation were given, then the average passing depth and the changes of probability density distribution of passing depth with energy or time were calculated. By analysis, the average passing depth of the high energy proton in the film was calculated. The probability density distribution of the passing depth represents the probability that protons pass to a certain depth.
