ITER project and RF systems

ITER is an international project supported by seven partners: China, Europe, India, Japan, Korea, Russian Federation and USA. Formally established in 2006, construction has started in France, more precisely in Provence. General progress of the project is presented followed by a focus on the RF systems which will provide 40 MW into the plasma, based on systems around 50 MHz and 170 GHz. These systems are using high power grid tubes, gyrotrons, and the latest power supplies technology to feed kilometres of transmission lines connected to specific antennas located at a few centimeters from the hot burning plasma.
