X-RAY DIFFRACTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To easily adjust a monochrometer, by reducing the number of parts to be adjusted in the monochrometer for an X-ray diffraction apparatus using a curved crystal. SOLUTION: A diffraction X-ray P from a sample through a detection slit 8 enters a spectral crystal 9 while spreading. Only Kαrays are reflected by the spectral crystal 9 and detected by a detector 10 set adjacent to the crystal 9. What is to be adjusted in this monochrometer is solely the distance between the detection slit and the spectral crystal and a rotating position of the spectral crystal. The rotating position of the spectral crystal 9 mounted to a crystal rotary stage 13 is adjusted by manipulating a crystal rotation knob 14 so that the intensity of detected X rays becomes maximum.
