- Abstract
- Process of guiding of short-focus electron beams, generated by High-Voltage Glow Discharge Electron Guns (HVGDEG), from low to high vacuum, is considered in this article on the base of theoretical analyse. Basic electron-optical equations for trajectory analyse, described interaction of the electron flux with magnetic field of focused lenses and with residual gas, were used for simulation of electron beam transporting in the equipotential channel. Main distinguishing feature of proposed model is taking into account the dissipation of thermal electrons' velocities after its passing through anode plasma of High Voltage Glow Discharge (HVGD). Obtained theoretical results are in the good agreement with experimental data.
