摘要
基于CH柱形靶压缩实验的时间分幅诊断需求,研制了4.75keV能点四通道Kirkpatrick-Baez(KB)显微镜。进行了四通道KB系统的光学设计、像质模拟和分析。采用支撑锥芯的方式解决了四通道KB物镜的集成装配问题,并通过"4.75keV+8keV"双能点多层膜完成了实验室内的KB系统装调。该套系统在神光Ⅱ装置成功进行了像质考核实验,获得了高分辨的四象限网格图像,成像间距符合设计要求,具备了开展时间分幅惯性约束聚变物理实验的条件。
To meet the requirement of framing diagnosis of CH cylindrical target implosion experiments, a four-channel 4.75 keV KB microscope was developed. The optical structure and imaging quality of the four-channel KB microscope were ana- lyzed. With the size limit of framing camera taken into account, the problem of assembly of the four-channel KB microscope has been solved using reference cone core. The assembly and alignment experiments of the four-channel KB microscope were per- formed in the laboratory. The clear image of four-quadrant grid with a spatial resolution of 3 μm in central field was obtained in Shenguang-Ⅱ laser facility, and the image spacing meets the design requirements, indicating that inertial confinement fusion framing experiments could be carried out.
