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 BWO`s with uniform structures. Efficiency enhancement has also been reported in vacuum BWO`s with slow wave structures having nonuniform ripple amplitude. These experiments have been conducted at the University of New Mexico (UNM) on the UNM Long-Pulse BWO Experiment. Data such as microwave power, efficiency, spectral content, and pulse duration will be presented. Details of the novel plasma injection system will also be presented including plasma parameters such as species concentration, plasma density, and temperature.
