Electric field in thin dielectric slabs irradiated by electrons

In the present work the study of the electric field distribution in thin dielectric slabs irradiated by plane-parallel electron beams has been made. The energy of incident electrons was considered from 1 to 10 MeV. The used slabs have thickness from 0.0005 to 0.05 g/cm² and are made of materials with atomic numbers between 4 and 79. The data of charge-deposition density of secondary electrons have been obtained by the means of a new Monte Carlo method (called the trajectory translation method). Basing on these data a semi-empirical model that describes the electric field distribution in the considered slabs has been developed. It has been noted that the data obtained by using this model describe well enough the electric field distributions in the considered slabs. The dependency of the electric field on different parameters such as energy of incident electrons, thickness and atomic number is also discussed
