VARIATIONS OF HELICON WAVE-INDUCED RADIAL PLASMA TRANSPORT IN DIFFERENT EXPERIMENTAL CONDITIONS

Variations of the helicon wave-induced radial plasma transport are pre sented depending on values of the plasma radius, magnetostatic field, plasma density and the frequency of the helicon wave. It is shown that the value of the helicon wave-induced transport may be significant fo r plasma confinement; this is demonstrated for the experiments BASIL a nd SHEILA. Whereas m = +1 helicons induce an inward-directed transport and thus improve the confinement, m = -1 helicons induce an outward-d irected transport velocity.
