Evolution of the quasilinear diffusion coefficient normalized to the collisional diffusion plotted versus the parallel refractive index at the antenna and for various radial location quasi-linear diffusion coefficient plotted versus n//, for different radial positions. Note that lines regarding the radial positions x = 1.10 and x = 1.01 are quite overlapped and cannot be distinguished. Antenna spectrum: Δn// ≡ 0.083. Other parameters as in Fig. 5.
