Abstract :
The problem of a reliable electron source is one of a crucial issue in efficient operation of relativistic microwave tubes. In this report we present results of comparison of experimental research of the relativistic magnetron operation with commonly used explosive emission plasma cathode and novel ferroelectric plasma source cathode. The latter allows one to form the plasma prior to the accelerating pulse and to control the plasma parameters using the different amplitude of the driving pulse and different time delay between the plasma formation and the application of the accelerating pulse.
