Toroidal equilibrium analysis of an axisymmetric plasma

Summary form only given. For controls and stability of an axisymmetric toroidal plasma, such as a tokamak or a reversed field pinch. The authors have developed the code-solving Grad-Shafranov (GS) equation as a free boundary condition including external poloidal coil currents. Using the flux function of a toroidal field proposed by M. Suzuki et al. (1992), the authors analyzed the toroidal equilibrium of a reversed field pinch configuration, including finite pressure gradient and external poloidal coil currents. Calculated results on the toroidal effect on the F-/spl theta/ curve and the RFP equilibrium with a poloidal divertor are presented.
