| Abstract: | A semianalytic multimode model that includes the instantaneous influence of a static error field on the resistive wall mode (RWM) is presented. The asymptotic behavior of the RWM as the marginal stability is approached, including the influence of the error field, is discussed. The influence of neighboring modes on the central harmonic modes is explored, allowing a less destabilizing error field spectrum to be proposed. The model has been applied to a plasma surrounded by a HBT‐EP tokamak type feedback system. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
