Powerful wideband amplifier based on hybrid plasma-cavity slow-wave structure

The powerful beam-plasma amplifier operating under continuous conditions is described. The amplifier is designed on the base of new principles using hybrid plasma-cavity electrodynamic structures. The theory and foundation of calculating the slow-wave structures having plasma filled propagation channel and interaction of electron beam with hybrid plasma-cavity system are considered. Considerably increased power of microwave radiation and expansion of the operating pass-band when the propagation channel is filled with plasma is shown.
