摘要
在稳态近似下通过求解速率方程分别计算了有无M带高能光子存在下, 不同温度密度下Cl等离子体的离化度分布以及发射谱, 研究了高能光子对等离子体发射谱的影响。研究发现:腔内混有的少量M带高能光子几乎不影响等离子体中重要的离化度分布, 但是会激发或者电离各种离子的内壳层电子, 从而对发射谱产生重要的影响。因此有M带高能光子存在时, 用发射谱诊断等离子体温度时需要同时考虑温度、密度和M带高能光子对发射谱的影响。
Abstract
The emission spectra of Cl plasma are calculated by solving the rate equations under conditions with and without M-shell high-energy photons at different temperatures and densities. The influences of the M-shell high-energy photons on the emission spectra are studied. It is found that the M-shell high-energy photons hardly affect the important ionic stage of the plasma, but they can excite or ionize the inner-shell electrons (e.g. 1s electron) of the ions in the plasma, hence affect the emission spectra. Therefore, if there are M-shell high-energy photons, the influence of temperature, density and M-shell high-energy photons on the emission spectra should be considered simultaneously.
