Ion Cyclotron Resonance Heating System on EAST

摘要

Ion cyclotron resonance heating (ICRH) system which will provide at least than10 MW heating power, with a frequency range from 25 MHz to 100 MHz, is being built up for theEAST. The system includes high-power and wide-frequency radio amplifier, transmission line aswell as resonant double loop (RDL) antenna. As a part of this system a sub-ICRH system unitwith a ultimate output power of 2.5 MW was set up and employed for heating experiment. Themaximum of the launched power reached 200 kW in 2008.
