On the influence of alpha-particle cyclotron damping on the lower hybrid current drive

Abstract

Some preliminary results of the influence of the cyclotron harmonic damping of lower hybrid waves by thermonuclearly produced alpha-particles are presented. Recently, the usefulness of the lower hybrid current drive (LHCD) in reactor regime was doubted in connection with this effect. The quasilinear change of the slope of the alpha-particle distribution function is taken into account. Analytical estimates are obtained showing that at a sufficiently high wave energy density the power absorped by alpha-particles saturates (in the approximation used). For the parameters of a hybrid reactor, the saturated power was found much lower than that computed from the linear theory. It seems, therefore, that, at least for hybrid reactor conditions, the alphaparticles need not represent a serious obstacle to LHCD. Some further aspects of this effect are discussed.
