An algorithm of calculation of the focal distance of a hollow conical electron beam, formed by high voltage glow discharge electron guns, as well as the calculation of the diameter and thickness of a focal ring of such a beam, are considered in the article. The proposed algorithm is based on the model of free moving of electrons in the anode plasma and formed on the base of the laws of electron optics with using the methods of discrete mathematics and minimax analysis. Obtained simulation results allow to find the important regularities, which characterized the dependencies of focal parameters of a hollow conical electron beam, formed by the high voltage glow discharge electron guns, on the constructive parameters of electrodes’ system of the electron gun.References
