Investigations of High-Power Beam Plasma Interactions
Abstract
This research is directed toward the investigation of high-power beam plasma interactions, with specific investigation of the transverse velocity beam modes called for. Experimental results have been obtained for the propagation characteristics of the transverse plasma wave models. They are qualitatively consistent with a traveling backward wave propagating toward the axis in a nonuniform plasma column whose density decreases toward the outside. The observed wavenumber is about twice that predicted by the theoretical dispersion relation based on a Maxwellian electron velocity distribution function. The theory has been reformulated to accommodate arbitrary distribution functions. The two-beam experiment has been completely set up in a form which prevents interaction in the varying perpendicular velocity region.
