Energy spectrum of an electron beam multiply reflected from the target

The effect of inelastically scattered electrons on the pulsed-beam energy spectrum are studied for the case where they hit back the target upon reflection from the accelerating region. The beam is formed in a vacuum diode and transported to the target by the guiding magnetic field. The formulas for the total and differential fluxes of different-order absorbed and backscattered electrons are presented. It is shown that account of multiple electron backscattering gives rise to a considerable change in the behavior of the normalized heat-source function in the target: the energy loss near the surface of the irradiated target increases markedly due to its reduction in the deep layers of the material.
