Abstract :
The paper is concerned with the problems of creating pulsed power sources for high-power microwave devices, using magnetron guns with metallic cold secondary-emission cathodes as electron sources. Consideration has been given to certain ways of generating specially shaped cathode voltage pulses, and experiments were made to initiate the secondary emission process and electron beam generation using these pulses
