Abstract

The topologic study of a stochastic magnetic field is investigated by the tracing of magnetic field lines. The first method consists of direct integration of the field lines. The first method consists of a direct integration of the field line equations. An alternative approach is to invoke the incompressibility of the magnetic field to formulate a Hamiltonian description of the magnetic field lines. The third and last approach consists of building a canonical map with the help of the Hamiltonian that models the magnetic topology without approximations; this is a general map.

These three methods are applied to the TEXTOR tokamak device with a magnetic field perturbation driven by the DED coils. .
