Effective plasma inductance computation

The calculation of the resistive wall modes and their feedback stabilization is greatly simplified by splitting the plasma response from that of the external conductors. Existing calculations either consider highly simplified models of the external conductors or assume the plasma response can be approximated by a single rigid mode. The full response of an ideal, nonrotating plasma to perturbations that evolve slowly compared to the Alfven time is contained in the matrix for the effective plasma inductance {lambda}<=>. This matrix can be used in a code that accurately calculates the effects of the external conductors to obtain an essentially complete description of both plasma and the conducting structures. Calculations of {lambda}<=> for a number of tokamak equilibria are given together with an explanation of how the calculations are made and why they are important.
