摘　　要：在激光惯性约束聚变(ICF)研究中,涉及X射线时间、空间和能谱信息的等离子体诊断能够为数值模拟提供关键的实验数据支撑,有效推进对ICF关键物理问题的认识。以Kirkpatrick-Baez(KB)结构为代表的多通道掠入射系统是实现高分辨X射线时空成像的重要手段,在ICF诊断研究中有着广泛的应用。主要介绍了高分辨多通道KB成像系统的发展历史,梳理和分析了KB系统研制的瓶颈问题,在此基础上重点展示了国内近年来在基于多层膜光学的多通道KB诊断系统研制方面取得的研究进展。随着精密薄膜器件和掠入射X射线光学集成等关键技术的突破,多通道多层膜KB成像系统已经在我国ICF诊断研究中得到广泛应用,有力保障了国内ICF研究单位相关物理实验的开展。In the research of laser inertial confinement fusion(ICF),plasma diagnostics involving X-ray time,space and energy spectrum provides key experimental data for numerical simulation,and effectively promotes the understanding of key physical problems of ICF.The multi-channel grazing-incidence system represented by Kirkpatrick-Baez(KB)microscope is an important means to realize high-resolution X-ray spatial-temporal imaging,which has a wide range of applications in ICF diagnostics research.This paper mainly introduces the development history of high-resolution multi-channel KB imaging system,analyzes the bottleneck problems in the development of KB systems,and focuses on the domestic research progress in the development of multi-channel KB diagnosis system based on multilayer optics in recent years.With breakthroughs in key technologies such as precision thin-film devices and grazing-incidence X-ray optical integration,multi-channel multilayer KB microscope has been widely used in domestic ICF diagnostics,which effectively guarantees the development of relevant physical experiments.
