Study on X-ray line emission diffraction in inertial confinement fusion and its recent progress

  • 摘要: 介绍了惯性约束聚变研究中X射线线谱诊断与各物理量之间关系,并对X射线晶体谱仪诊断方式及诊断原理进行了简要说明。针对不同类型诊断,介绍了常用不同类型衍射晶体的作用与原理。此外,介绍了最近开展的一种新型变锥面弯晶X射线诊断方法研究,此方法拥有高集光效率的同时,保证了后端接收装置的精巧耦合,减小了像差。以变锥面弯晶衍射特性研究为出发点,开发了一个X射线任意面型晶体衍射追迹仿真软件X-Chase,并以国内某大型激光装置类H、类He线的变锥面晶体诊断为例进行了计算演示,数值模拟结果显示了变锥面晶体具有很好的聚焦效果。
