Abstract
The excitation of eigen surface waves by tubular electron beams in cylindrical discharge devices is studied. The influence of the wave-field azimuthal structure on the excitation efficiency and nonlinear stage of the plasmabeam instability is investigated both numerically and analytically. Analytical expressions for the saturation amplitude and excitation efficiency of the wave under study are derived. They are found to agree well with results obtained by numerical modelling of the plasma-beam interaction presented in this paper. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
