论文摘要
提出了一种简化而直接的方法，可用于通过塔利夫技术在强烈发射的等离子体中测量n（4 s）密度。该方法利用吸收峰强度而不是完全集成的吸收线强度。这种方法的使用以及基于物理的拟合/过滤程序可以强烈降低实验不确定性和执行测量，即使在强烈排放的放电中也是如此。验证后，采用该方法研究强烈发射的微波排放的瞬变。我们尤其表明，在从高力阶段过渡的早期阶段，n（4 s）密度的意外增加。考虑到详细的状态动力学，使用自洽的准共生等离子体模型，使这种增强归因于n（2 d）和n（2 p）的表面脱位。
A simplified and straightforward methodology that may be used to measure N(4 S) density by TALIF technique in strongly emissive plasmas is presented. The method makes use of the absorption peak intensities instead of the fully integrated absorption line intensity. The use of this method, along with a physics-based fitting/filtering procedure enables strongly reducing the experimental uncertainty and performing measurement even in strongly emitting discharges. After validation, the method was employed to investigate the transients of a strongly emissive pulsed microwave discharge. We especially showed the existence of unexpected increase of N(4 S) density at the early stage of the transition from high-to lowpower phase. The use of a self-consistent quasi-homogenous plasma model taking into account a detailed state-to-state kinetics, enables to attribute this enhancement to surface deexcitation of N(2 D) and N(2 P).
