Plasma filling of high-power backward wave oscillators with nonuniform slow wave structures

Summary form only given. This paper presents the first data describing experiments conducted with plasma filled, nonuniform, backward wave oscillators (BWO). Previous studies have indicated enhanced microwave power output and efficiency in plasma filled BWOs with uniform structures. Efficiency enhancement has also been reported in vacuum BWOs with slow wave structures having nonuniform ripple amplitude. Data such as microwave power, efficiency, spectral content, and pulse duration are presented. Details of the novel plasma injection system are also presented including plasma parameters such as species concentration, plasma density and temperature.
