Toward 3D MHD modeling of neoclassical tearing mode suppression by ECCD
FOM Institute DIFFER – Dutch Institute for Fundamental Energy Research, Association EURATOMFOM, Trilateral Euregio Cluster, the Netherlands, http://www.differ.nl
We propose a framework to extend the magnetohydrodynamic (MHD) equations to include electron cyclotron current drive (ECCD) and discuss previous models proposed by Giruzzi et al.  and by Hegna and Callen . To model neoclassical tearing mode (NTM) instabilities and study the growth of magnetic islands as NTMs evolve, we employ the nonlinear reduced-MHD simulation JOREK. We present tearing-mode growth-rate calculations from JOREK simulations.
