title: Far-infrared laser scattering studies of density fluctuations in tokamak fusion plasmas.
abstract: Development of a far-infrared Thomson scattering system for the study of density fluctuations in fusion plasmas is described. New data are presented of naturally occurring low-frequency microturbulence and also of electrostatic modes generated at the ion cyclotron range of frequencies (ICRF). The latter studies are important in understanding ICRF supplementary heating experiments. They have produced the first internal observation of mode-converted ion -Bernstein waves in a tokamak plasma.
