Abstract :
A powerful beam-plasma amplifier operating under continuous conditions is described. The amplifier is designed on new principles using hybrid plasma-cavity electrodynamic structures. The theory and foundation for calculating slow-wave structures having a plasma filled propagation channel, and the interaction of an electron beam with a hybrid plasma-cavity system, are considered. Considerably increased power of microwave radiation and expansion of the operating pass-band is shown to result when the propagation channel is filled with plasma. The use of new principles makes it possible to create an amplifier with an efficiency and 3 dB operating band width higher than those attained in vacuum devices
