RF Ion Source Achieves High Power Plasma Discharge with Long Pulse of 1000s

Aug 27, 2019

Chinese scientists have realized the long pulse of 1000s plasma discharge with RF power of 82 kW, marking a new milestone in the development of China's high power radio frequency (RF) ion source.

The large area RF ion source is one of the key parts of neutral beam injector on fusion device. The research and development of RF ion source involves many disciplines, such as precision machinofacture, physics of RF plasma, RF power transmission and matching, RF power coupling and feedback control of plasma discharge.

The R&D team of ion source in neutral beam injection division of Institute of Plasma Physics, Hefei Institute of Physical Science of Chinese Academy of Sciences, has solved a number of bottleneck problems, and developed a large area RF ion source to achieve long pulse plasma discharge of 1000s with high power of 82kW for the first time.

They believe that this may lay a good foundation for the development of high power RF ion source.
