Time-resolved optical emission spectroscopy studies have been made to investigate the elemental/charge composition of the plasma ionic component at pulsed reflex discharge. The discharge plasma has are registered spectral lines neutral atoms and ions of the working gas Ar, Ar 1+ , Ar 2+ , and also of the cathode material: Zr, Zr 1+ , Zr 2+ , Zr 3+ . The presence of zirconium in the spectrum attests to the entry of cathode material into the plasma and its subsequent ionization. The variation of spectral line intensity with time in the early stage of the discharge and in the stage of dense plasma existence (time interval from the onset of the discharge up to 4 ms) correlates with the dynamics of plasma parameters. Characteristic times of appearance of excited atoms and ions in the plasma have been determined. The time of appearance of excited Zr* atoms is by the order of magnitude longer than that of Ar*. The stage of high-voltage mode ...

大功率脉冲反射放电中多电荷态离子的观察

已经进行了时间分辨的光发射光谱学研究，以研究脉冲反射放电下等离子体离子组分的元素/电荷组成。放电等离子体具有工作气体Ar，Ar 1+，Ar 2+以及阴极材料Zr，Zr 1+，Zr 2+，Zr 3+的配准谱线的中性原子和离子。光谱中锆的存在证明了阴极材料进入等离子体及其随后的电离。在放电的早期和密集的等离子体存在阶段（从放电开始到4 ms的时间间隔），光谱线强度随时间的变化与等离子体参数的动态相关。已经确定了等离子体中激发原子和离子出现的特征时间。激发的Zr *原子的出现时间比Ar *的出现时间长几个数量级。高压模式阶段...
