ABSTRACT:
An x-ray diffractometer is equipped with a position sensitive detector and a collimator preceding the detector. The lamellae of the collimator are radially aligned to the specimen, which is arranged in the center of a measurement circle along which the detector and collimator move during a measurement. Therefore, only the x-radiation scattered at the specimen contributes to the measured signal. An elliptically deformed multi-layer mirror is provided at the primary beam side, which deflects the source radiation in the direction of the specimen without great intensity loss and focuses it at a point lying on the measurement circle. Analysis of powdered specimens that are enclosed in glass capillaries can be undertaken. A low-background measurement of diffraction diagrams in an x-ray diffractometer given efficient use of the primary beam is achieved.
