Abstract

Computer simulations have been carried out to investigate the effects of a dense background plasma on the dispersion characteristics of backward wave oscillators. It is observed that the background plasma tends to reduce the phase velocity of the most unstable mode. As a result, a strong efficiency enhancement is found. On the other hand, the relatively weak beam-backward plasma wave instability introduced by the rippled waveguide wall is found to exert negligible impact on the interaction efficiency.
