Abstract
We present an application of short-pulse laser-generated hard x rays for the diagnosis of indirectly driven double shell targets. Cone-inserted double shell targets were imploded through an indirect drive approach on the upgraded SG-II laser facility. Then, based on the point-projection hard x-ray radiography technique, time-resolved radiography of the double shell targets, including that of their near-peak compression, were obtained. The backlighter source was created by the interactions of a high-intensity short pulsed laser with a metal microwire target. Images of the target near peak compression were obtained with an Au microwire. In addition, radiation hydrodynamic simulations were performed, and the target evolution obtained agrees well with the experimental results. Using the radiographic images, areal densities of the targets were evaluated.
我们介绍了短脉冲激光产生的硬 X 射线在间接驱动双壳目标诊断中的应用。在升级版 SG-II 激光设备上，通过间接驱动方法对锥形插入式双壳目标进行了内爆。然后，基于点投影硬 X 射线射线照相技术，获得了双壳靶的时间分辨射线照相，包括其近峰值压缩的射线照相。背光源是由高强度短脉冲激光与金属微线靶相互作用产生的。使用金微线获得了目标接近峰值压缩的图像。此外，还进行了辐射流体力学模拟，得到的目标演变与实验结果非常吻合。利用射线图像，对目标的面积密度进行了评估。
