对于实验室天体物理界来说，那些在天文学中广泛使用的光谱建模代码，例如Chianti，AtomDB，Cloudy和Xstar，不能直接应用于分析实验室测量结果，因为它们与天体物理案例存在差异。例如，来自电子束离子阱的等离子体具有遵循高斯分布而不是麦克斯韦分布的电子能量分布。激光驱动内爆产生的紧凑物体的实验室微型显示出偏离平衡，这经常发生在天体中，因此我们建立了一个光谱分析系统，用于天体物理和实验室（SASAL）等离子体作为它们之间的桥梁，这有利于实验室天体物理界。
For the laboratory astrophysics community, those spectroscopic modeling codes extensively used in astronomy, e.g. Chianti, AtomDB, Cloudy and Xstar, cannot be directly applied to analyzing laboratory measurements due to their discrepancies from astrophysical cases. For example, plasma from an electron beam ion trap has an electron energy distribution that follows a Gaussian profile, instead of a Maxwellian one. The laboratory miniature for a compact object produced by a laser-driven implosion shows a departure from equilibrium, that often occurs in celestial objects, so we setup a spectral analysis system for astrophysical and laboratory (SASAL) plasmas to act as a bridge between them, which benefits the laboratory astrophysical community.
