Abstract

A review of the present status of the performances of Electron Cyclotron Current Drive (ECCD) in ITER is presented. Injection of EC power is considered from both the Upper Launcher and the Equatorial Launcher taking into account the actual design of the launching system, aiming at different physical effects. Key objectives of the whole system are central heating, q profile control and stabilization of magnetohydrodynamic instabilities, mainly Neoclassical Tearing Modes and sawteeth. Investigations relevant to different ITER standard scenarios are reported, as well as to reduced toroidal field scenarios. ECCD sensitivity to the chosen scaling of plasma parameters at reduced fields is discussed. Calculations have been performed using the GRAY code. A discussion on the validity of the theoretical models used for the computation of EC propagation, absorption and current drive is presented with reference to plasma parameters and EC launching conditions such as those foreseen in ITER. © 2009 World Scientific Publishing Co.
