Experiments on the Relation Between Radiation and Fluctuation Spectrum of a Turbulent Plasma

Abstract
The experimentally observed radiation from unstable plasma waves generated by the interaction of an electron beam with a plasma is compared with the longitudinal fluctuation spectrum, determined by incoherent microwave scattering. The results are in agreement with a theory by Ichimaru and Starr for the electromagnetic radiation from anisotropic turbulent plasmas.
