针对间接驱动情况下，冲击波诊断中出现的X光离化问题，利用半导体模型，解释了蓝宝石和石英晶体材料中出现黑区的理论过程，并进行了实验验证。利用光生载流子模型分析了石英晶体中时间方向上出现调制的过程，并进行了实验验证。发现使用石英晶体作为窗口材料，使用60 μm厚度的烧蚀层，在180 eV辐射温度条件下，没有出现明显的黑区。使用金层做阻挡层，可以有效避免X光离化现象的出现，从而为辐射驱动条件下冲击波诊断技术发展提供了参考。

When the shock wave is diagnosed under indirect drive, the ionization effect caused by the X-ray in the Al2O3 and quartz has been explained with semiconductor model. And the model explanation has been confirmed by the experimental data. In the experimental data, the signal modulation in quartz on time scale has been confirmed with photo-carrier model. It is found that there is not clear “blank” effect in the quartz even if the radiation temperature is 180 eV with 60 μm ablation. The “blank” effect can be avoided obviously after the Au is used as the blocking layer. And this method provides the diagnosis way for shock wave under indirect drive.
