Abstract

The perturbation of the ion density is evaluated using a fluctuating distribution function obtained as solution of the drift kinetic equation in passing particle regime. The radio-frequency heating is taking into account by pitch-angle-scattering part of the quasilinear radio-frequency operator. The radial variation of ion density perturbation is studied for terms generated by both the turbulence and ion cyclotron resonance heating (ICRH). The supplementary term of the ion density perturbation obtained here must be included in the quasi-neutrality condition usually used to determine the dispersion relation of the instability, crucial in the study of the turbulence..
