Monte Carlo simulations used for the type of interaction of fast particles with atoms and electrons of the target; the state of primary particles of the atom, the electron gas and secondary particles. The parameters of the spatial distribution of ions for thousands of combinations of ion-target, and for dozens of them - Simulation. It showed that hundreds of thousands of samples to ion secondary distribution model parameters are different from the theory of a few percent. It can be used in industrial processes to predict the properties of solids and irradiated films on the depth interval near the maximum, where the concentration decreases by 2-3 orders of magnitude. For fullerite on the silicon substrate simulated distribution of secondary electrons in it their way and accumulated charge, depending on the dose, the energy beam and film thickness. It is shown that changes in the film occurs in the area that is far removed from the axis of the beam, and the major contribution they make to the low energy secondary electrons. The results can be used in industrial processes to change the properties of films using known electron beam energy and beam power to determine the measurements accumulated in the film detector charge.
