Abstract
A simple thin-section holder equipped with selector apertures for the selected area X-ray diffraction has been designed for four-circle diffractometer. In making thin-section, an acrylic resin plate was employed instead of a conventional slide glass to reduce the absorption of X-rays. The selector aperture is easily moved and placed on an aimed area in thin-section under the microscope. Single crystal diffraction data from the selected area with diameter as small as 60 μm have been successfully obtained, although the measurable diffraction area is smaller than the case of usual single crystal method. The holder can also be applicable to X-ray cameras using universally used single crystal goniometer heads.
