Abstract
A converse KAM method for 3D vector fields, establishing regions through which passes no invariant 2-tori transverse to a given direction field, is tested on some helical perturbations of an axisymmetric magnetic field in toroidal geometry. It finds regions corresponding to magnetic islands and chaos for the fieldline flow. The minimization of these regions is proposed as a tool to help in the design of plasma confinement devices of tokamak and stellarator type.
