中文摘要： 同步辐射X射线微探针利用微米/亚微米X射线微束，结合扫描微束X射线荧光成像、微束X射线衍射和微束X射线吸收谱等多种实验方法，可以对物质成分、结构及其分布进行高空间分辨、高灵敏的探测，是生物、环境和材料等广泛领域开展前沿科学研究的强有力手段。目前，利用同步辐射X射线微探针对样品进行综合的分析实验需要用户在多个操作界面进行复杂的操作，包括：微米/亚微米精度的样品对光，多种探测器、样品台和显微镜的参数设定和切换等，要求用户对同步辐射X射线微探针实验方法和装置有比较深入的了解，限制了同步辐射X射线微探针的实验效率和推广应用。本项目将在上海光源硬X射线微聚焦光束线站的基础上，开展硬X射线微探针自动化技术研究，结合实时数字图像处理技术和基于EPICS的控制和数据采集技术，实现X射线微探针实验的高度自动化，只需用鼠标在单个用户界面进行少量的操作既可完成对样品进行的多种实验方法.

英文摘要： By utilizing micron / submicron X-ray microbeam, combining with a variety of experimental methods, including scanning microbeam X-ray fluorescence imaging, microbeam X-ray diffraction and microbeam X-ray absorption spectrum, synchrotron radiation X-ray microprobe can make high spatial resolution and high sensitive detection to the composition, structure and distribution of materials, which is the important methodology to study leading edge scientific research on a wide range of areas, such as Biology, Environment and Materials. At present, to analyze the samples by means of synchrotron radiation X-ray microprobe, users are required to take complex operations on multiple user interfaces, including put the sample to the beam in micron / submicron scale, a variety of detectors, the sample stages and the microscopic parameter setting and switching. All of these operations require users to have in-depth understanding about experimental methods and devices of synchrotron radiation X-ray microprobe, which limited its experimental efficiency and popularity. Based on hard X-ray microfocus beamline station in SSRF, combined with real time digital image processing technology and EPICS based data acquisition and control technology, this project will focus on study about automation technology of hard X-ray microprobe so that
