Abstract

The work represents generalization of methods for Calculations of energy losses and electron beam geometry at its leading to the dense media through the system of differential exhaustion. Methods of approximate calculations of scattering at multiple collisions with atoms are considered. Parameters of magnetic systems for beam focusing are considered justified, optimal length for transport channels is determined. Method of «enlarged interactions» for numerical computation of cross section of the beam is analyzed.
