PURPOSE:To permit easy adjustment in the stage of exchanging crystals by rotating the driving shaft of a position adjusting mechanism for spectral crystals by as much as the amt. stored preliminarily for each of the spectral crystals. CONSTITUTION:An electron beam (e) is irradiated to a sample S. The sample S, a spectral crystal 2 and an X-ray exit slit 3 are disposed on a Rowland circle R. The base B of the X-ray spectroscope is pivotally supported to a body with the point A as a fulcrum. When a shaft 5 is rotated, the base B turns and focusing is accomplished. When a shaft 4 is rotated, an arm L turns and the angle of the crystal around the axis perpendicular to the plane of the figure is adjusted. A control circuit C drives pulse motors M1, M2 at every exchange of the crystal 2 according to the driving amt. stored for each of the spectral crystals. |
