The algorithm is considered for calculating the focal distance of a hollow conical electron beam generated by high-voltage glow discharge electron guns with magnetic focusing of the beam in the drift region, as well as a method for calculating the diameter of the focal ring and its thickness for such a beam. The proposed algorithm is based on the theory of electron drift in the field of a focusing magnetic lens and is designed using the methods of discrete mathematics and the minimax analysis. The obtained simulation results made it possible to establish the influence of the magnetic lens current on the focal diameter of a hollow conical electron beam and on its focal ring thickness. It is shown that the change in the focal parameters of a hollow conical electron beam can be effectively provided through the regulation of the magnetic lens current.

This paper deals with studying into the modes of burning and structure of the glow discharge with a hollow cathode and a flat anode in argon. We have demonstrated that the electron beam usually leaving the cathode cavity in a high voltage (glow mode) disappears when the anode approaches the edge of the hollow cathode. In this case the discharge is burning only on the outer surface of the cathode plates forming the cavity. The anode motion does not affect essentially the properties of the discharge burning in the hollow mode. We have obtained the axial intensity profiles of the emission lines of argon atoms and ions in the hollow and glow modes for various gas pressure and discharge current values. We have also shown that the brightest lines correspond to the transitions from 3p54p to 3p54s levels. The lines corresponding to the transitions from higher levels as well as the emission lines of argon ions possess a rather low intensity.
