摘　　要：在激光间接驱动惯性约束聚变(ICF)领域中,获得具有极高空间分辨率(优于5μm)的X射线辐射图像,是研究烧蚀不稳定性、内爆流线等关键物理过程的数据基础。基于掠入射反射式成像原理的Kirkpatrick-Baez(KB)显微成像系统作为一种具有高空间分辨率和集光效率的X射线显微诊断设备,目前已成为国际ICF装置的X射线关键诊断设备。在神光Ⅱ和神光Ⅲ原型装置条件上开展了KB诊断技术及设备的研究,在KB系统的光学设计、光学元件和物镜与系统装调技术等方面取得了许多重要进展,研制了大视场KB、多色KB等高分辨率X射线显微成像系统。这些系统已应用于我国的ICF内爆芯部发光和流线测量、流体不稳定增长测量等实验中,为关键物理量的测量提供了高空间分辨率的清晰图像。In the field of indirect-drive inertial-confinement-fusion,to acquire high spatial resolution X-ray radiation images is the foundation for hydrodynamic instabilities and imploded process researches.Kirkpatrick-Baez（KB）microscope,which is based on the principles of grazing-incidence X-ray imaging,is an X-ray diagnosis device presenting an extra-high spatial resolution and a big total solid angle of collection.The KB microscope has been an international key X-ray diagnosis device on ICF facilities.We have investigated KB devices on SG-Ⅱ and SG-Ⅲ prototype facilities and made remarkable progresses on optical design,optical component preparation and assemblage technology of objective mirrors.A large object-field KB microscope and a multi-energy KB microscope have been developed.These KB microscopes have been applied in the hydrodynamic instabilities and implosion experiments,and performed high-resolution high-magnification images of key physical data for laser-fusion plasma research.
