PURPOSE: To obtain a measured result with high reliability by preventing the arrival of scattered X-ray generated at the place of a shielding member at an X-ray detector in an X-ray apparatus. CONSTITUTION: A single crystalline sample 3 is sealed in vacuum by shielding members 9, 10, and further cooled by liquid nitrogen flowing in a passage 6. A plurality of X-ray shielding plates 15 suspended from a top plate 14 are radially disposed a outside the member 10 having the sample 3 at the center. The X-rays passed through a collimator 4 is projected through the members 9, 10 to the sample 3, and the refracted X-ray is again passed through the members 9, 10 to arrive at storage fluorescent phosphor 5 to form energy latent image therein. The scattered X-rays generated at the X-ray passing points P1-P4 of the members 9, 10 are shielded by a plurality of X-ray shielding pates 15 rotatably moved around an axis L1 as the center, and not arrives at the phosphor 5. |
