In toroidal plasmas, external magnetic field perturbations, either resonant or non-resonant, have been used in MHD instability control. These perturbations cause magnetic island, stochastic regions, or deformed magnetic structures, which interact with equilibrium plasmas and/or intrinsic plasma flow to result in change in MHD properties. In real toroidal plasmas, even in axisymmetric systems, equilibrium magnetic field is three-dimensional because there are many sources of asymmetric field errors.

In this Workshop, we will discuss on characterization of the toroidal equilibria from weak to strong three-dimensionality, interaction of external magnetic perturbations with such 3-D toroidal plasmas, including the effect of intrinsic plasma flow. We believe such efforts have significant contribution to ITER and DEMO reactor design studies.
