摘要：
Backward wave oscillators (BWO's) driven by high-current relativistic electron beams are capable of producing high-power coherent radiation in the centimeter and millimeter wavelength regions, However, the efficiency of these devices is usually limited to 15-20% when a homogeneous slow-wave structure is used, Utilizing a two-section slow-wave structure, where the spatial period of the second section is larger than that bf the first section, a BWO efficiency of greater than 50% was calculated, A conceptual design of a high efficiency S-band BWO driven by a 500-kV 5-kA electron beam has been developed and analyzed.
