Popis: | In our previous paper [V. Lazurik, V. Moskvin and T. Tabata, IEEE Trans. Nucl. Sci. 45, pp. 626-31 (1998)] the average depth of electron penetration, R/sub av/, has been introduced as the average of the maximum depths on the trajectories of electrons passing through a target. In the present work the dependence of R/sub av/ on the angle of incidence of an electron beam has been studied. A semi-empirical equation is derived to calculate R/sub av/ as a function of angle of incidence. We extend the study of R/sub av/ from using it to characterize the average behavior of electron beams in a target to describing the generation of secondary electrons by photon beams. It is shown that R/sub av/ can be used in a wide variety of applications in which the characteristic size of the spatial region of electron production is important. |
