Popis:	The ICRF heating and current drive system for the KSTAR tokamak is being developed to support long pulse, high β, advanced tokamak physics experiments. Key ICRF components such as a water-cooled, high power density (∼10 MW/m2) antenna, a vacuum feedthrough for 1 MW of RF power transmission, and the tuning and matching components for slow/fast matching, are developed. High voltage characteristics and long pulse operation capability are investigated in KAERI test stand. Test results show that they have high voltage stand-off characteristics with the peak voltage over 30 kV and they can be used for long pulse (300 s) high RF power transmission.
