ABSTRACT

A numerical dynamic model is developed for axially symmetric cathode-ray tubes. Its operating capacity is proved by the simulation of an elementary component of the cathode-ray tube (CRT), a diode cell, and by the juxtaposing of the results calculated with the help of the model with known analytic relationships and experimental data. The possibilities of the model are shown when performing computing experiments. In particular, the influence of edge effects on the volt-ampere characteristics (VACs) in the elementary cell was studied. A method is developed for the calculation of the fluctuation characteristics of electron beams.
