| Annotation | The paper presents a general method of modeling the electron beam formation processes in the axially-symmetric systems. This method is based on the experimental current-voltage characteristics of a typical three-electrode electron-optical system, on the numerical analysis of the electric fields in the electrode gap and on the trajectory analysis in the previously calculated fields. The method is tested by numerical experiments at predetermined intervals of the real voltages on the focusing electrodes and can be recommended for the practical realization of the electron-beam devices for different purposes. |
