Plasma Relativistic Microwave Amplifier and Oscillator

Summary form only given. Plasma relativistic microwave amplifier is tuned from 2 to 3 GHz. Spectra and the phase difference of the input and output signals were measured. The output microwave power is 30 to 70 MW, the amplification is 30 dB, the pulse duration is 70 ns. In the plasma relativistic oscillator the feedback suppression was observed due to the normal Doppler effect. First results of experiment with the plasma microwave oscillator in repetitively-rate regime are presented.
