Analysis and Optimization of the Impact of Ferromagnetic Inserts on the Toroidal Field Ripple in ITER

The discreteness of the toroidal field (TF) coils causes toroidally asymmetric perturbations of magnetic field (TF ripple). Maximum value of the TF ripple produced in the plasma by ITER TF coils is 1.16%. The ripple requirements are determined by loss of fast particles and by potential changes in H-...

Description
Summary:The discreteness of the toroidal field (TF) coils causes toroidally asymmetric perturbations of magnetic field (TF ripple). Maximum value of the TF ripple produced in the plasma by ITER TF coils is 1.16%. The ripple requirements are determined by loss of fast particles and by potential changes in H-mode characteristics. The fast particle behavior is well known and a maximum TF ripple at the plasma separatrix of
