Toroidal effects on the non-linearly saturated m = 1 island in tokamaks
This paper investigates the influence of toroidal effects (due to the coupling of various poloidal harmonics) on the non-linear saturation of the m=1 island. Bounds are obtained relating the aspect ratio, the shear at the q=1 surface and the saturated island width. Provided these bounds are satisfied, the cylindrical m=1 island theory of A Thyagaraja and F A Haas (to appear in Physics of Fluids B) is valid for toroidal geometry.
