Original abstract

The paper presents numerical simulations of a hairpin thermionic electron gun, an electron source for an electron-beam welding machine. New algorithm for the simulation of emission limited by space charge has been developed and implemented in the program EOD, which enables us to simulate the optical system as whole. The results of the simulation were compared with the experimental measurements.

V článku jsou prezentovány simulace vlásenkového elektronového zdroje pro elektronovou svářečku. Byl vyvinut nový algoritmus pro simulaci emise limitované prostorovým nábojem a implmementován jak knihovna programu EOD. Tento algoritmus umožňuje simulaci opticých systémů jako jednoho celku. Výsledky simulace jsou porovnány s experimentem.
