Experimental investigation of the current diffusion in tokamak discharges
This paper investigates a scaling law to describe the effect of external discharge parameters such as current pulse shape, particle density, toroidal magnetic field and plasma contamination on the current diffusion processes in the TEXTOR tokamak. In all discharges under investigation, the simple Ohm's law with neoclassical resistivity is approximately valid during current diffusion. A model formed on the basis of the current diffusion equation and the electron energy conservation equation is used to provide a physical interpretation of the scaling law.
