Quasilinear absorption of lower hybrid waves in tokamak plasmas
Wave propagation and absorption in the lower hybrid (LH) frequency domain are studied using a ray tracing code which solves the equations for the trajectories in the geometric optics approximation. This has been implemented and coupled to a code that solves the Fokker-Planck equation (FPE) with an added quasilinear diffusion term for the electron distribution function F(e). In this paper, the electron dynamics are described using the FPE in one-dimension to obtain an analytical distribution function, based on the assumption that the dependence of the electron distribution function on the perpendicular velocity is Maxwellian.
