SIMULATION OF PROPAGATION OF ELECTRON BEAMS FORMED BY HIGH-VOLTAGE GLOW DISCHARGE ELECTRON GUNS FROM LOWER TO HIGHER VACUUM

Based on the solution of a system of algebraic-differential equations for the boundary trajectory of an electron beam, the physical process of transporting short-focus electron beams in an ionized gas has been researched. Theoretical analysis is mainly focused on defining of the focal parameters of short-focus electron beams generated by high-voltage glow discharge electron guns. The obtained theoretical results are in good agreement with experimental data. The corresponding computer software for implementing algorithms for modeling the transportation of shortfocus electron beams in ionized gas was developed using the Python program language.
