| 内容記述 | In the EC-driven (8.2 GHz) steady-state plasma on QUEST, plasma current seems toflow in the open magneticsurface in the outside of the closed magnetic surface in the low-field region according to plasma currentfittingmethod without taking equilibrium into account. In our previous work, plasma equilibrium solution wasfittedassuming all plasma current isflowing in the inside of the Last Closed Flux Surface (LCFS). It was solved withinisotropic pressure profile by EFIT code. Opposite-polarity current density region appeared in the high-fieldregion. Here in this article, considering the toroidal rotation, the equilibrium isfitted within nested magneticsurfaces by SU-EFIT. Though the plasma magnetic axis shifts outward due to the centrifugal force, the oppositepolarity current does not disappear in the high-field region. And relation between the toroidal rotation speed andthe poloidal beta value will be discussed | |||||
