The plasma wall interaction in large tokamaks poses serious problems requiring control of the energy exhaust, control of the particle exhaust, screening of the plasma core against impurities and shielding of the first wall against hot charge exchange neutrals and against high convective or conductive power loads. This paper investigates the configurations with the poloidal and toroidal mode numbers m = 18 and n = 6 using Fourier analysis. To achieve an almost uniform power deposition at the first wall, the perturbation pattern is not allowed to be static but rotating.
