DIAGNOSTIC OF THE STATE OF A LASER-PRODUCED Al PLASMA USING SPECTRAL LINES OF He-like Al ION

本文详细叙述了利用He-like离子的特征谱线诊断等离子体的电子密度和电子温度的方法,给出了共振线与双电子伴线的强度比随电子温度的变化曲线和共振线与互组合线的强度比随电子密度的变化曲线。并且根据实验测得的上述两组谱线的强度比,定出激光产生等离子体的电子温度和电子密度。

In this paper, we explain the diagnostic method of electron temperature and density of a laser-produced plasma using spectral lines of He-like Al ion in detail; the intensity ratios of satellite to resonance line vs the electron temperature and resonance to combination line vs electron density have been given, respectively. Meanwhile, according to the line intensity ratios from experiment, the electron temperature and density for He-like Al ion have been determined.
