Abstract

The model used in the present work suffers from several limitations; in particular it treats only the one- dimensional Fokker-Planck equation, and uses a rude procedure to cope with the problem of runaway production. This model is local and devised to be used in a radial ? power deposition code. Nevertheless, it permits to relate grossly the local absorption to the total input power, which allows to draw the following conclusions from the above results. A saturation of the absorbed power is reached; this happens for injected power comparable to those observed experimentally. The "upshift" - required to account for the magnitude of the actually driven current - is provided by a secondary lobe like the one usually contained in the launched spectrum if this can penetrate into - or be created in - the plasma volume.
