摘要
利用共轭原理设计了用于惯性约束聚变的束靶耦合传感器,不仅解决高精度打靶,同时避免模拟准直光在瞄准过程中直接辐照实验靶。根据束靶耦合传感器的设计功能和工作原理,进行系统的光学设计和机械结构设计,通过成像实验采集的图像光学分辨力达到6 μm,束靶耦合精度8.8 μm。该束靶耦合传感器已经成功应用于神光-Ⅲ原型装置,通过针孔相机采集的四孔CH靶图像,统计计算得到装置的打靶精度优于25 μm,满足设计打靶的束靶耦合精度的指标。
Abstract
A sensor based on conjugate principle has been designed for matching the light beams and the target in inertial confinement fusion. It can avoid the direct illumination of the simulation collimating light on the target under test in targeting processes. This paper introduces the optical and mechanical design of the sensor, according to its design functions and working principle. The resolution of the optical images obtained in experiments reaches 6 μm and the beam-target matching accuracy is 8.8 μm. The sensor has been successfully applied to the Shenguang-Ⅲ facility. Statistical analyses of the four-hole CH target images derived with pinhole camera shows that the targeting accuracy of the facility is better than 25 μm, satisfying the design requirements.
