Abstract:
An imaging-plate-type X-ray diffraction apparatus comprising:(a) means for causing a set single-crystal sample to diffract X-rays, said means comprising an X-ray optical system and a goniometer, the sample being set on the goniometer; (b) a single cylindrical imaging plate disposed vertically so as to record X rays diffracted by the sample, and covering a continuous 2&thgr; goniometry range of âˆ’60Â° to +144Â°, said goniometer being disposed at a position located inside said cylindrical imaging plate and corresponding to a lower portion of said cylindrical imaging plate, without interference with the X-ray optical system and said cylindrical imaging plate, such that an axis of the sample is positioned vertically; (c) a cylindrical carrier providing a continuous support surface in contact with and coextensive with an outside cylindrical surface of said cylindrical imaging plate and retaining said cylindrical imaging plate; (d) transfer means for vertically transferring said cylindrical carrier with said cylindrical image plate retained by said cylindrical carrier; and (e) a rotary reader disposed so as to be coaxial with said transferred cylindrical imaging plate and adapted to read data of diffracted X-rays from an inner cylindrical surface of said cylindrical imaging plate, with said cylindrical image plate retained by said cylindrical carrier.
