ABSTRACT:
A goniometer in an X-ray diffraction device comprises a sample table rotatably provided about a center axis of a sample for holding a sample, an X-ray source rotatably provided about the center axis of the sample for irrdiating first X-ray onto a sample, and an X-ray detector rotatably provided about the center axis of the sample for detecting second X-rays resulting from the irradiation of the first X-rays, the second X-rays being diffracted X-rays depending upon a sample. The sample table, the X-ray source an the X-ray detector are rotatable independently of one another, and a component to be fixed can be freely selected in accordance with a purpose of measurement and sample attachments employed. As such, various kinds of measuring methods are available to perform X-ray diffraction analysis by a single goniometer.
