Progress of the RF negative hydrogen ion source for fusion at HUST
文献摘要：
Huazhong University of Science and Technology has developed an experimental setup of a radio frequency(RF)driven negative hydrogen ion source,to investigate the physics of production and extraction of the H-ions for neutral beam injection in nuclear fusion reactors.The main design parameters of the ion source are:RF power≤40 kW;extraction voltage≤10 kV;accelerator voltage≤20 kV.This paper gives an overview of the progress of the ion source with particular emphasis on some issues.The RF driver and source plasma are analyzed and optimized in terms of impedance matching,plasma characteristics and power coupling.In regard to the simulation analysis,a plasma model based on the particle-in-cell method and a beam trajectory model considering beam stripping loss are developed to investigate the plasma and negative ions transport inside the ion source.Furthermore,a collisional radiative model of H and H2 is built for plasma optical diagnosis.
