辐射驱动冲击波速度诊断是辐射驱动聚变和物质状态方程(EOS)研究的重要诊断技术,无论是用冲击波法测量辐射温度还是研究物质状态方程,都对冲击波速度测量精度有较高要求.论文介绍开展的辐射驱动冲击波速度不确定度分析的理论工作,提高了数据处理的准确性.通过建立自动化数据处理平台,将靶参数、条纹相机精密标定数据库以及冲击波图像的处理有机地结合起来,实现了对冲击波速度以及多个参数量对冲击波测量不确定度影响的快速评估.目前神光系列实验中冲击波速度测量的不确定度在1.5％以内.%Diagnosis of radiation - driven shock wave velocity measurement is an important technique in the study on radiation - driven fusion and equation of state, both of which need high precision shock wave velocity measurement. Theoretical work on uncertainty analysis of radiation - driven shock wave velocity measurement is presented which improves the accuracy of data processing. A data processing platform is established which automatically manipulates target parameters, calibration database of streak camera and shock wave images, and quick evaluation of shock wave velocity and analysis of multi - parameter influences on its uncertainty are realized. Uncertainty of shock wave velocity measurements in the experiments carried out in Shenguang - serie laser facilities is obtained within 1.5%.
