Dynamic simulation of electrons in the injector of sealed vacuum chamber of industrial betatrons

The paper researches some difficulties that emerge in the production of series small-sized betatrons. In particular, disadvantages of electron injector construction and attributed problems are described. Analysis of the results of mathematical simulation of the dynamics of electrons in the injector of the sealed acceleration vacuum chamber of serial betatrons was carried out. The problem areas were highlighted in the injector of electrons requiring to be improved. (paper)
