Abstract
The distribution of the magnetic lines in a tokamak plasma per — turbed by resonant helical windings is considered. A Hamiltonian perturbation theory is applied to investigate the break-up of magnetic surfaces inside the plasma for large aspect-ratio tokamaks. This effect is also investigated integrating numerically the line equations, obtaining a Poincaré mapping of these non-integrable fields in order to analyse the extent of satellite magnetic islands and chaotic regions. Average invariants are also obtained to describe approximately the field lines distribution inside the plasma.
