In this paper, we present a model characterizing the interaction of a radiative shock (RS) with a solid material, as described in a recent paper (Koenig et al., Phys. Plasmas, 24, 082707 (2017)), the new model is then related to recent experiments performed on the GEKKO XII laser facility. The RS generated in a xenon gas cell propagates towards a solid obstacle that is ablated by radiation coming from the shock front and the radiative precursor, mimicking processes occurring in astrophysical phenomena. The model presented here calculates the dynamics of the obstacle expansion, which depends on several parameters, notably the geometry and the temperature of the shock. All parameters required for the model have been obtained from experiments. Good agreement between experimental data and the model is found when spherical geometry is taken into account. As a consequence, this model is a useful and easy tool to infer parameters from experimental data (such as the shock temperature), and also to design future experiments.

与辐射冲击相互作用的固体障碍物膨胀的分析模型

在本文中，我们提出了一个表征辐射冲击 (RS) 与固体材料相互作用的模型，如最近的一篇论文 (Koenig等。, 物理。等离子，24, 082707 (2017))，然后新模型与最近在 GEKKO XII 激光设施上进行的实验相关。氙气室中产生的 RS 向固体障碍物传播，该固体障碍物被来自激波前沿和辐射前体的辐射烧蚀，模拟天体物理现象中发生的过程。这里介绍的模型计算障碍物膨胀的动力学，这取决于几个参数，特别是冲击的几何形状和温度。模型所需的所有参数都是从实验中获得的。当考虑球面几何时，发现实验数据和模型之间的一致性很好。因此，该模型是从实验数据（例如冲击温度）推断参数以及设计未来实验的有用且简单的工具。
