Abstract

In this paper the analysis of the plasma shape equilibrium and fitt ing (EFIT) control arithmetic is described. The physics concept ion of EFIT arithmetic applied in Tokamak is introduced firstly. Then the flux function is described using Grad-Shafranov equilibrium equation in MHD. Finally, the main flow chart and funct ions group of this arithmetic are introduced, especially fitting arithmetic.
