TSC Simulation of Feedback Stabilization of Axisymmetric Modes in Tokamaks using Driven Halo Currents
Authors: S.C. Jardin and J.A. Schmidt
The Tokamak Simulation Code (TSC) has been used to model a new method of feedback stabilization of the axisymmetric instability in tokamaks using driven halo (or scrapeoff layer) currents. The method appears to be feasible for a wide range of plasma edge parameters. It may offer significant advantages over the more conventional method of controlling this instability when applied in a reactor environment.
