Abstract

Among the useful properties of a high Tc superconductor (HTSC), the pinning effect included in these properties is considered effective one to reduce a plasma instability in the tokamak reactor. This is because the magnetic flux lines produced by plasma current are trapped in the pinning centers, and the trapping force reduces its motion. However, a proper operating scenario of plasma current ramp-up phase is necessary to achieve a practical stabilizing effect, This paper proposes an operating scenario of plasma start-up for the purpose of optimizing the stabilization method of tokamak plasma by using the HTSC. The operating scenario was designed by introducing several compensation coils. According to computed results, this operating scenario has fully feasibility.
