摘要

摘要: 在神光Ⅱ三倍频装置上，由黑腔产生的辐射驱动铝台阶样品产生冲击波，采用光学条纹相机测量冲击波速度，利用冲击波速度与黑腔辐射温度的定标关系，获得了与软X光能谱仪测量相一致的辐射温度；采用热波关系和能量守恒原理对辐射温度进行了分析，计算结果与实验结果一致。

Abstract: The D shaped cavity has been used to measure the radiation temperature in Hollraum on Shenguang Ⅱ laser facility. The radiation temperature was measured using two methods. One method measured the shock wave velocity produced in low-Z materials such as Al driven by the emission from hohlraum. The shock velocity was detected using optical streaked camera to observe the optical signal emitted from the rear of a step Al placed over a hole in the cavity wall. The second method measured the re-radiated X-ray flux from the cavity wave viewing through another hole in the cavity with soft X-ray spectrometer. Both methods have been shown to provide a consistent characterization of the X-ray drive in the cavity target. The experimental results were analyzed using a model that was based on heat wave similarity and energy conversation law.
