In this work we have conducted a study on the radiative and spectroscopic properties of the radiative precursor and the post-shock region from experiments with radiative shocks in xenon performed at the Orion laser facility. The study is based on post-processing of radiation-hydrodynamics simulations of the experiment. In particular, we have analyzed the thermodynamic regime of the plasma, the charge state distributions, the monochromatic opacities and emissivities, and the specific intensities for plasma conditions of both regions. The study of the intensities is a useful tool to estimate ranges of electron temperatures present in the xenon plasma in these experiments and the analysis performed of the microscopic properties commented above helps to better understand the intensity spectra. Finally, a theoretical analysis of the possibility of the onset of isobaric thermal instabilities in the post-shock has been made, concluding that the instabilities obtained in the radiative-hydrodynamic simulations could be thermal ones due to strong radiative cooling.

在猎户座激光设施进行的辐射冲击实验的微观特性分析

在这项工作中，我们通过在猎户座激光设施进行的氙辐射冲击实验，对辐射前体和冲击后区域的辐射和光谱特性进行了研究。该研究基于实验的辐射流体动力学模拟的后处理。特别是，我们分析了等离子体的热力学状态、电荷状态分布、单色不透明度和发射率，以及两个区域等离子体条件的特定强度。在这些实验中，强度研究是估计氙等离子体中存在的电子温度范围的有用工具，对上述微观特性的分析有助于更好地理解强度光谱。最后，
