Abstract

A radio frequency (RF) driven ion source has been developed at ASIPP (Institute of Plasma Physics, CAS) for the neutral beam injector with a 1 MHz, 25 kW RF power supply system. The paper describes the studies performed with emphasis on the RF matching network system design based on the dedicated Smith chart analyses to improve and simplify the optimized solution. Also the future RF matching network design was analyzed with the matching transformers which were set between the high-power RF transmitter and the RF driven ion source to isolate the high voltage from the accelerator of the ion source.
