GENERATION OF ELECTRON BEAMS IN MAGNETRON GUNS WITH SECONDARY EMISSION CATHODES OF A SMALL DIAMETER

This paper is concerned with investigations on electron beam generation in magnetron guns with cold secondary-emission metallic cathodes of a small diameter with a large aspect ratio. The parameters of electron beams are given as a function of electric and magnetic field values using different methods of voltage pulse formation for secondary-electron multiplication and beam generation

Вимоги до системи електричного розряду у плазмово-хвильовій системі

The electrical circuit creating a pulse arc is analyzed. The requirements to the elements of an electrical circuit in the electrical discharge circuit applied in the plasma-wave system are considered [1]. For analysis a discharge gap as a loading in the similar circuits is offered. The experience of practical realization of the circuit under consideration is given. Dynamics of an energy release in the channel of a pulse arc being characteristic for the chosen discharge circuit is experimentally established.Проведено аналіз електричного кола газового розряду.
