Численное моделирование движения электронов в электрическом поле аксиально-симметричных электронно-оптических систем

Abstract

In work the design procedure of fields and trajectory the analysis of electron beam for axial-symmetric electron-optical systems is offered. Calculation of structure of electrical field is based on the dividing all electrodes to elementary charged parts. With computer modeling is used method of Everhart for forming envelope of electron beam. Attached method keep in mind influence of space charge, energy spread and direction spread of electrons. Calculations for concrete electron-optical system which correlate with results before the received experimental data are carried spent.
