摘要
利用碰撞辐射平衡和离化平衡下的等离子体X射线发射谱理论,对镁元素等离子体在中低电子密度、中高电子温度范围内,以碰撞激发、共振激发、离化、辐射复合和双电子复合等动力学过程为主的Mg10+、Mg9+和Mg8+三离子体系X射线谱进行了理论模拟,得到其X射线光谱,反映出X射线辐射谱波长、强度同电子温度之间的关系,得到了等离子体诊断所关心的电子温度的定性关系.
The collisional-radiative model from the FAC （flexible atomic code） is used to simulate Mg plasma consisting of Mg^10＋ ,Mg^9 ＋ and Mg^8 ＋ , which is a general application to the calculation of Mg spectrum of collisionally ionized plasma, it includes the recombination and ionization process in the line formation. An X-ray spectra from the Li-like Mg plasmas is obtained, which shows the relations between X-ray wavelengths, relatively radiative intensity and the electronic temperature, which are important to plasmas diagnostics.
