  Discharge Structure Hierarchy of Highly Electronegative Plasma and The Implication on Nuclear Fusion at Low Pressure and Quasi- Cold Ions Approximation
  Author(s): Rui-Ji Tang, Shu-Xia Zhao* and Yu Tian
  
  In this paper, the discharge structure of an Ar/SF6 inductively coupled plasma (ICP) at the low pressure is investigated by the fluid simulation at the quasi- cold ions approximation. The structure is found to be hierarchal and in this simulated hierarchy, the stratification, the parabola profile in the stratified core, the double layer, and the coagulated profile in the core center are examined. This fluid simulation version and a quasi- fluid simulation of an Ar/CF4 ICP given by the HPEM code, cooperatively enlighten the discharge structure of highly electronegative ICPs and meanwhile suggest the potential applications of them. It is found that when the ions are cold the hierarchy is predicted and when the ions are thermalized the simple discharge structure appears. In the simulated hierarchy, the double layer formed at the interface of halo and core is given by the ionic and acoust.. Read More»
