Description
Reversal of the impurity flux as a possible means to avoid large impurity concentrations in a Tokamak plasma has been discussed already in several papers. Flux reversal can in principle be obtained a) by additional heating, either R.F. heating or neutral injection, leading to a steepening of the ion-temperature profile and thus to an enhancement of the thermal diffusion b) by influx or neutral gas from the outside. In the following the combined effects of additional heating by neutral injection and of neutral gas influx on the impurity transport in a Tokamak plasma (TEXTOR) is considered as well as, for comparsion, the effect of each measure alone.

Abstract (German)
Richtungsumkehr des Verunreinigungsflusses ist ein moegliches Mittel, um grosse Konzentrationen von Verunreinigungen in einem Tokamak-Plasma zu vermeiden. Im Prinzip kann das erreicht werden durch zusaetzliche Plasmaheizung und/oder durch Zustrom von Neutralgas von aussen. Mathematisch und rechnerisch abgehandelt werden sowohl die kombinierten Effekte als auch jeder Effekt fuer sich allein. (orig./GG)Additional details
