[PPS10-P08] Development of integrated SR-CT method for the total analysis of meteorites
Keywords:synchrotron radiation tomography, XRD-CT, meteorite
Recently, several methods of the combination of x-ray diffraction (XRD) and CT were developed in the material sciences of engineering fields [e.g. 1-2], and performed precise observation of polycrystalline metals or alloys. We can determine the mineral phases of the sample uniquely, orientation of the crystals inside them and analyze their chemical composition by linear attenuation coefficient .
In this paper, we report a new instrument for the total analysis of rocky material which includes XRD, SR-CT, and local tomography which images a region of interest of a sample by zooming up it. We also developed softwares for the integrated analysis of data obtained by the system. The software relates the images and data obtained by those different methods with simple operation. Using this system, we can search and investigate certain materials or minerals included in the sample, such as carbon phases. We also introduce future developments and application for analysis of materials obtained by future sample return missions.
