Imaging plate X-ray diffraction apparatus

摘要

A space-efficient imaging-plate-type X-ray diffraction apparatus featuring an expanded 2theta goniometry range, high speed, high resolution, and design for convenient use is provided. The imaging-plate-type X-ray diffraction apparatus includes an X-ray measurement device composed of an X-ray optical system (5) and a goniometer (1) and is adapted to cause a single-crystal sample (3) to diffract X-rays. A cylindrical imaging plate (21) is disposed vertically so as to record X-rays diffracted by the sample (3), and covering a 2theta goniometry range of -60° to +144°. A drive motor (11) and a transmission mechanism (12) transfer the cylindrical imaging plate vertically; and a rotary reader (20) is disposed so as to be coaxial with the transferred cylindrical imaging plate (21) and is adapted to read data of diffracted X-rays from an inner cylindrical surface of the cylindrical imaging plate (21).
