各种天体物理学和实验室等离子体的X射线和EUV光谱学--碰撞、光电离和电荷交换等离子体
X-ray and EUV spectroscopy of various astrophysical and laboratory plasmas -- Collisional, photoionization and charge-exchange plasmas
摘要：
几个实验室设施被用来基准的理论光谱模型广泛使用的天文学界。然而，在天体物理环境和可以存档的实验室微缩模型之间仍然存在许多差异。本文建立了一个SASAL等离子体光谱分析系统，在它们之间架起一座桥梁，研究了非热电子对类日冕、光电离和地日冕等离子体的影响、亚稳态能级布居对能级布居的贡献以及电荷级分布。实验室测量（即EBIT等离子体）和天体物理观测（即彗星，天鹅座X-3）的测试应用。研究了碰撞等离子体和光电离等离子体的电荷态和能级布居随时间的演化。
英文摘要：
Several laboratory facilities were used to benchmark theoretical spectral models those extensively used by astronomical communities. However there are still many differences between astrophysical environments and laboratory miniatures that can be archived. Here we setup a spectral analysis system for astrophysical and laboratory (SASAL) plasmas to make a bridge between them, and investigate the effects from non-thermal electrons, contribution from metastable level-population on level populations and charge stage distribution for coronal-like, photoionized, and geocoronal plasmas. Test applications to laboratory measurement (i.e. EBIT plasma) and astrophysical observation (i.e. Comet, Cygnus X-3) are presented. Time evolution of charge stage and level population are also explored for collisional and photoionized plasmas.
