Wave absorption in the lower hybrid frequency range
Abstract
The paper is concerned with the relative importance of various absorption mechanisms in the lower hybrid heating of thermonuclear plasmas. Linear absorption is described in terms of the kinetic theory of plasma waves propagating in an inhomogeneous magnetized plasma. Situations pertinent to wave absorption in toroidal discharges are considered, and parameters relevant to thermonuclear plasmas are used. The damping of quasi-longitudinal plasma waves in inhomogeneous cylindrical magnetized plasma is considered. The collisional dissipative process is described with attention to the influence of collisions on the wave conversion efficiency and the ion resonant interaction. Low-frequency kinetic parametric instabilities are examined, and lower hybrid heating of thermonuclear plasmas is discussed.
