Abstract :
Presented in this paper are the results of 3-D simulation of the secondary-electro multiplication process in a magnetron with cold secondary emission Pd-Ba alloy cathode in which the primary electron sources are the blade-shaped field emitters. The application of the anode voltage pulse tandem is conducive to improving the efficiency and reliability of triggering the electromagnetic self-oscillation excitation in magnetron oscillator, as the nanosecond radiation pulses are generated.
