Abstract
A linear theory of the excitation of electromagnetic waves in a plasma filled backward wave oscillator driven by an intense relativistic ele ctron beam is presented. It is found that the spatial growth rate of b ackward wave instability exhibits a resonant increase for a particular value of fill-plasma density. We compare our results to the experimen t by Minami et al. on a high power backward wave oscillator.
