Two different approaches to control the Toroidal Field Ripple (TFR) amplitude in ITER and FAST devices are presented in this paper. The approach currently adopted to reduce the TFR in ITER is based on the installation of ferromagnetic inserts between the vacuum vessel shells. The same approach has been analyzed in the design of the Fusion Advanced Studies Torus (FAST) proposal. Details of the system's layout are given. A new approach based on the insertion of active coils between the outer legs of the Toroidal Field Coils (TFCs) and the plasma, has been extensively investigated for these two machines. This active system would allow reducing the TFR to values even smaller than with the ferromagnetic inserts. The case of a localized disturb like that introduced by a Test Blanket Module (TBM) for ITER is presented where only well localized active coils can produce a significant ripple reduction. © 2009 Elsevier B.V.
