Research on the Discharge Simulation of Radio Frequency Ion Source for EAST Neutral Beam Injector
Listed in ScienceDB
Neutral beam injection (NBI) is one of the most efficient means of four auxiliary plasma heating means and has been applied to drive current in nuclear fusion physics studies.
Description
The high current ion source is one of the key components of neutral beam injector, its performance determines the achievable goals of the EAST NBI. For the purpose of satisfying long pulse operation and the future demands of high energy ion source of NBI, the RF ion source was developed and studied to replace the traditional hot cathod ion source.
This paper aims to study the fundamental physical characteristics of radio frequency plasma discharge. Two-dimensional inductively coupled plasma model is used to carry out numerical simulation for RF ion source. The simulation results give the optimal parameters of the RF ion source for EAST NBI.
