| Research Abstract |
A high angular resolution Gandolfi camera with the camera radius of 955mm was successfully developed for 3rd generation synchrotron X-ray source. With the Gandolfi camera we successfully observed high quality powder X-ray diffraction data from a small volume natural samples that composed of several mineral crystals. We have adopted the camera for analysis of small particles recovered from the surface of an asteroid "Itokawa" by the JAXA's space prove," Hayabusa". As the result of plagioclase thermometry using the X-ray powder diffraction data obtained by the Gandolfi camera, the crystallization temperatures of the plagioclase were determined.
