Abstract

A realistic description of the physics of heating and current drive by LH waves in tokamaks would involve wave propagation in toroidal plasmas, absorption by strongly distorted electron and ion distribution functions, and transport processes. If one wants to do something simpler, retaining the physics, we may adopt a simplified model for the propagation, keeping the calculation of the absorption by the strongly distorted distribution functions. Transport processes take place on a longer time scale with respect to the quasi-linear generation of the tail distribution function (d.f.) and can be neglected at least in a first approach. In this paper the authors present a calculation of the power deposition profile in LH heated plasmas, using such a model. In Sec. 2 the model is briefly described; in Sec. 3 the results obtained in applying it to Ft experiments are discussed; conclusions follow.
