Abstract :
Recent progress on the high power mm wave technologies of the electron cyclotron heating and current drive (EC H&CD) for ITER (international thermonuclear experimental reactor) application is introduced. The R&D and design works are under progress at EU, Russia, US, India and Japan. On the 170 GHz gyrotron developments, the ITER criterion (1MW, 500s, 50%), which was the most critical issue for EC H&CD system, has been satisfied. Accompanied with the progress of the power sources, the development of the components is accelerated, such as mm wave transmission line. In addition, specific design works of launchers for mm-wave injection into the plasma have advanced.
