摘要：
A combined numerical-analytical model for the electron-optical system of a large-area accelerator is suggested. The model is used to analyze various electron and optical factors that affect the beam extraction coefficient. To find ways of improving the beam extraction coefficient, the spatial and angular characteristics of the beam are calculated in various cross sections. The effect of the magnetic field produced by the cathode filament current is studied in detail for the first time. (C) 2003 MAIK "Nauka/Interperiodica".
