Outline of Final Research Achievements

Confocal three-dimensional X-ray diffraction (XRD) method was developed for crystalline phase distribution analysis in inhomogeneously multicomponent mixed samples.
A focusing optic was put as an incident channel in front of an X-ray tube. 2θ arm was built on a rotation stage and a scintillation detector was put on it. The second focusig optics was set in the front of a scintillation detector. Both focal points were overlapped on the rotating center of the rotation stage. An inhomogeneous sample composed of binary materials was set on a X-Y-Z sample stage and the diffraction pattern from a crystalline phase on the confocul point was observed by 2-theta scanning. The Diffraction patterns were collected while scanning the sample. The distribution of crystalline phases in the sample was checked and the spatial resoution was etimated. Using the confoal XRD equipment, inhomogeneous samples were analyzed nondestructively.
