Description
A large diameter plasma filled backward wave oscillator(BWO) is investigated experimentally. The parameters of slow wave structure are chosen so that the oscillation frequency is about 20 GHz at 60 keV beam energy. plasma is produced by the beam and it has favorable effects on beam propagation and Cerenkov oscillation. The output power of the BWO with plasma is observed to be 3-6 times that of vacuum BWO. The power level of several kW and efficiency is about 0.01% are obtained. The output power strongly enhanced when the guiding magnetic field approaches to the fundamental electron cyclotron resonance. The maximum power of 490 kW with an efficiency of 4% is achieved even for a relatively low beam energy of 60 keV. (author)
