“…A powerful 24 MW Electron Cyclotron (EC) system [1,2] operating at 170 GHz with pulse lengths up to 3,600 sec is planned to be installed for the ITER tokamak that will be used for central heating and current drive (H&CD) applications as well as off-axis control of magneto-hydrodynamic (MHD) instabilities. Design work for the ITER EC system is moving forward with the following main functionalities:…”

The Electron Cyclotron (EC) system for the ITER tokamak is designed to inject ≥20 MW RF power into the plasma for Heating and Current Drive (H&CD) applications. The EC system consists of up to 26 gyrotrons (between 1 to 2 MW each), the associated power supplies, 24 transmission lines and 5 launchers. The EC system has a diverse range of applications including central heating and current drive, current profile tailoring and control of plasma magneto-hydrodynamic (MHD) instabilities such as the sawtooth and neoclassical tearing modes (NTMs). This diverse range of applications requires the launchers to be capable of depositing the EC power across nearly the entire plasma cross section. This is achieved by two types of antennas: an equatorial port launcher (capable of injecting up to 20 MW from the plasma axis to mid-radius) and four upper port launchers providing access from inside of mid radius to near the plasma edge. The equatorial launcher design is optimized for central heating, current drive and profile tailoring, while the upper launcher should provide a very focused and peaked current density profile to control the plasma instabilities.The overall EC system has been modified during the past three years taking into account the issues identified in the ITER design review from 2007 and 2008 as well as integrating new technologies. This paper will review the principal objectives of the EC system, modifications made during the past two years and how the design is compliant with the principal objectives.

“…The RF H&CD systems (LH, IC and EC) deliver the power in an electro-magnetic wave to either the ions or electrons via resonance process [1,2]. Each of the RF H&CD systems is to couple up to 20 MW heating power to the plasma in CW operation, which is beyond what has been achieved on the previous tokamaks.…”
