Abstract

New type of axisymmetric magnetohydrodynamic (MHD) equilibrium of toroidally flowing plasma, which cannot be found in the framework of the ideal MHD, emerges due to the Hall and toroidal effects. If either of these effects is neglected, only a conventional MHD-type equilibrium is obtained. Numerical solutions of both types are calculated in toroidal geometries to simulate the equilibrium states in the Ring Trap-1 device constructed at the University of Tokyo. Numerical analysis shows that when the toroidal flow is increased, the plasma shifts inward in the new-type equilibrium, while in the MHD type the outward shift occurs due to the centrifugal effect.
