Abstract:
1. A sample cooling apparatus for cooling a sample, the apparatus being used in an X-ray diffractometer for rotating, about an ω axis, a sample supported by a sample-supporting component in order to change an angle at which X-rays impinge on the sample, directing X-rays on the sample, and detecting X-rays coming away from the sample using an X-ray detector, the sample cooling apparatus for the X-ray diffractometer comprising: cooling-gas-blowing means for blowing a cooling gas on the sample; and gas-suctioning means for suctioning, via an aperture, gas that has passed over the sample, wherein: the sample-supporting component moves when rotated about the ω axis so as to form a conical surface having the sample as a vertex; the cooling-gas-blowing means is provided so that the direction in which the sample-supporting component extends and the direction in which gas is blown by the cooling-gas-blowing means form a state of being an acute angle of equal to or less than 90°; the gas-suctioning means suctions the gas so that a path of the gas having contacted the sample-supporting component bends when the direction in which the sample-supporting component extends and the direction in which gas is blown by the cooling-gas-blowing means form the acute-angle state; and the gas-suctioning aperture of the gas-suctioning means integrally rotates about the ω axis together with the sample.
