Abstract

A new axisymmetric, free-boundary equilibrium code, FBT, has been developed and tested. The code allows the computation of arbitrarily shaped tokamak equilibria, with external or internal separatrices and multiple magnetic axes. It is shown that bifurcations can be controlled by an iterative procedure using shape feedback. Three specific applications are discussed: item"(1)" the problem of shape accuracy, item"(2)" the calculation of a startup evolution for a highly elongated tokamak, and item"(3)" methods to control saddle points.par
