Abstract:
A combinatorial X-ray diffraction apparatus for examination of plural samples arranged in a matrix of linear arrays as rows and columns, said apparatus comprising:(a) an X-ray source for radiating X-rays from a point-shaped focal point; (b) a curved monochromator which spectrally reflects the X-rays radiated from the X-ray source; (c) a first slit disposed for restricting radiation of the reflected X-rays to a measurement area; (d) a holder for holding, arranged in the matrix, the plural samples to be irradiated with the X-rays; (e) a knife-edge disposed relative to said holder to define a knife-edge slit therebetween further restricting the X-ray irradiation, having passed through said first slit, to a single linear array of said samples; (f) a two-dimensional detector for receiving diffraction X-rays reflected from at least one of the samples held by the holder; (g) a goniometer having a &ohgr;-axis shaft and a 2&thgr;-axis shaft, the holder being mounted on the &ohgr;-axis shaft, and the two-dimensional detector being mounted on the 2&thgr;-axis shaft; (h) a drive unit for moving the position at which the X-rays impinge the samples; (i) an information processing apparatus for fetching output data from the two-dimensional detector and processing the data; and (j) a display unit for displaying the result of processing performed in the information processing apparatus.
