This study considers certain systems composed of two electron beams, either in a gap or coupled to a slow-wave transmission line. The interaction of a single electron stream coupled to the fields of a resonant cavity is examined with particular attention to the effect of beam perveance on the apparent beam loading resistance. Experimental measurement verifies the existence of extrema in the maximum negative beam resistance as a function of the plasma transit angle, which is a normalized parameter proportional to perveance.
