摘要: 针孔相机是激光焦斑及打靶瞄准精度监测的主要工具。针对神光Ⅱ升级装置开展针孔相机的研制工作。通过各项参数和结构的优化设计，完成神光Ⅱ升级装置针孔相机诊断系统的设计、研制和集成调试，并进行性能测试实验。结果表明：针孔相机探测能区到达1.0～5.5 keV，空间分辨力优于20 m，放大倍率5.13～9.99。针孔相机可用于神光Ⅱ升级装置开展激光焦斑及打靶瞄准精度监测工作。Abstract: The pinhole camera is an important device for inspecting of laser focal spot and target pointing in inertial confinement fusion experiments. In this paper, the X-ray pinhole camera has been developed for ShengguangⅡ-up equipment. This study focuses on parameter and configuration optimization. And the devices have been designed, manufactured, assembled and tested. The results of test experiments show that the energy range is 1.0-5.5 keV, the spatial resolution is better than 20 m, and the magnification ratio is 5.13-9.99. That proves that the pinhole camera can be applied on ShengguangⅡ-up equipment.
