Abstract

The creation and diagnosis of plasma in high power microwave devices remains one of the primary challenges of plasma microwave electronics. The present work deals with (a) diagnostics techniques for characterization of radially nonuniform plasma columns suitable for use in high power microwave sources and (b) the effects of such plasmas on the electromagnetic properties of finite length, spatially periodic slow wave structures. Experimental studies were performed both for a strong and weak guiding magnetic field. Using a combination of a novel cylindrical resonant cavity technique supported by accurate numerical calculations of the plasma influence on cavity resonances of a long, thin plasma column one is able to characterize pulsed plasma columns. The peak density and the spatial distributions of the plasma was measured as a function of the applied magnetic field and the plasma gun operating conditions.
