The model of electrical and thermomechanical effects in the electron beam

The physical and mathematical model of thermomechanical effects which accompanies electron scattering in barrier is carried out. Model has taken into account bulk charge and electromagnetic field generation by beam’s electrons in barrier. The expressions for Lorentz force density, acting on ionized substance, and its Joule heating in the electromagnetic field are constructed. The estimations of electromagnetic field influence on thermomechanical processes are represented.
