Numerical simulation of distribution of electric field and particle trajectories in electron sources based on high-voltage glow discharge

Igor V. Melnyk


A new method is suggested for numerical simulation of self-congruent electron-ion optics in electron sources based on high-voltage glow discharge. The method uses the tubes of current and permits to consider the impact of recharges and the spread of electrons in velocities on the focal energetic parameters of the shaped electron beam. The simulation results are included.
