Title: Computation of three-dimensional tokamak and spherical torus equilibria

Abstract

A nominally axisymmetric plasma configuration, such as a tokamak or a spherical torus, is highly sensitive to nonaxisymmetric magnetic perturbations due to currents outside of the plasma. The high sensitivity means that the primary interest is in the response of the plasma to very small perturbations, i.e., vertical bar b-vector/B-vector vertical bar {approx_equal}10{sup -2} to 10{sup -4}, which can be calculated using the theory of perturbed equilibria. The ideal perturbed equilibrium code (IPEC) is described and applied to the study of the plasma response in a spherical torus to such external perturbations.
