The purpose of this study is to develop newly designed analyzing microscope which detects diffracted X-ray as well as fruolescence X-ray emitted from a sample with primary X-ray irradiation. This equipment will enable us to obtain the information of mineral composition and crystal structure of the sample simultaneously with that of chemical composition. There expected to be broad application field of the equipment in earth sciences or material sciences.In this study, we first developed an algorithm of a image analysis for XRF images obtained by the Scanning X-ray Analytical Microscope (SXAM). This algorithm transforms the XRF images into mineral distribution maps assuming linear relationship of XRF intensities with mineral composition. In the next step, we have been developing the equipment of XRF and XRD microscope. We established the conceptual plan of the equipment and constructed prototype device to determine optimal configuration of X-ray detecting system. Performance tests of the prototype is now on going.

本研究的目的是发展一种新设计的分析显微镜，它能同时检测衍射X射线和荧光X射线。该设备可在获取样品化学成分信息的同时，获取样品的矿物成分和晶体结构信息。在本研究中，我们首先开发了一种用于扫描X射线分析显微镜（SXAM）获得的XRF图像的图像分析算法。该算法将XRF图像转换成矿物分布图，假设XRF强度与矿物成分呈线性关系。下一步，我们一直在开发XRF和XRD显微镜的设备。建立了设备的概念方案，并构建了样机，确定了X射线检测系统的最佳配置。原型的性能测试正在进行中。
