Electromagnetic and Thermomechanical Effect Produced by an Electronic Beam on a Solid Barrier

摘要

The developed mathematical model simulates the thermomechanical effects which accompany electron scattering in a barrier. The generation of a space charge and an electromagnetic field is taken into account. For the ionized substance of the barrier and an electromagnetic field, Euler equations with the Lorentz force and Joule heating and Maxwell equations with a convective current are considered. Equations are constructed for the density of the Lorentz force acting on the ionized substance and for its Joule heating in the electromagnetic field. Conservative difference analogs of the quantities responsible for the interaction of the electromagnetic field with the ionized substance are developed.
