RESISTIVE WALL MODE IN ROTATING PLASMA WITH MULTIPLE WALLS

Resistive wall kink mode is studied in cylindrical plasma that is surr ounded by two resistive walls. The outer wall is regarded as active co ils for feedback stabilization, which can be made to fake-rotate. The impact of plasma rotation on such a scheme is investigated. It is foun d that plasma rotation at some sufficient rate can destabilize the res istive wall mode, which would otherwise remain stable by the fake-rota ting coil feedback scheme.
