Abstract
A study on the feedback stabilization of resistive wall modes in a cylindri cal geometry is presented. The effect of radial separation of feedback coil s from sensor loops is investigated. It is shown that there is an optimum r adial position for feedback coils where sideband mode coupling parameter is minimized, hence enhancing the efficacy of a system of coils for feedback stabilization of resistive wall modes.
