Abstract

The quasilinear modification of the ion distribution function during first harmonic ion cyclotron (FHIC) heating has been investigated with a simple, well established analytic one-dimensional approach and a new two-dimensional steady state solver of the quasilinear kinetic equation, SSFPQL. It is shown that in the case of IC heating the information required from the wave code for the construction of the quasilinear operator essentially reduces to the knowledge of the power deposition profile. Analytic solutions of a reduced, one-dimensional kinetic equation obtained by neglecting the anisotropy of IC heating are then presented. The SSFPQL is shown and results of its application to first harmonic heating in ASDEX Upgrade and ITER are described.
