Summary form only given. The stability of stationary states of dense electron beams propagating in weakly irregular channels, in particular, in channels with non-deep periodically corrugated walls, is investigated using the method of coupled waves. We show that Bursian's instability can develop, leading to the formation of virtual cathodes or their disruption. In unlimited channels, separate zones of absolute and convective instabilities on the omega-k plane (Brillouin's diagram) are possible… CONTINUE READING
