| 摘 要： | 在神光Ⅲ原型装置上开展了辐射驱动内爆自发射的高分辨多能点诊断技术研究。利用双周期多层膜KB的选能能点，配合多级记录系统，实现了内爆自发的高空间分辨准单色成像。实验结果表明，利用胶片可以获得发射2.5 keV和3.5 keV的清晰图像，利用CCD可以获得8 keV的窄能带清晰图像。实验结果可以很好用于芯部不对称性、电子温度分布以及密度分布的分析处理，为惯性约束聚变精密物理实验研究提供了新的诊断技术和方法。

| Abstract: | The high spatial resolution and multi-energy point diagnostic technology explores the core zone for ICF implosion on SG-Ⅲ prototype device. With the reflective properties of double-periodic multi-layer KB, bremsstrahlung radiation characteristics of implosion can be divided into three energy points. Three energy points images are recorded separately by multi-level recording medium, including a three-layer film and CCD. The experimental results show that 2.5 keV, and 3.5 keV clear images can be obtained using the films, and a 8 keV clear image can be obtained using the CCD. The results can be used for core analysis and processing of asymmetry, electron temperature and density distribution, The multi-level recording technology and the experimental technique based on multi-layer KB provide new diagnostic technique for ICF precision physics experiments. |
