Abstract: The finite difference and PIC method are used to simulate the behavior of secondary electrons stimulated by primary X-ray photoelectrons. The results are given for the air pressure below 1 Pa and the plasma effects of low energy secondary electrons to the irradiated conductor are discussed as well.

Key words: photoelectron, secondary electron, plasma, numerical simulation, finite difference
