DETECTION OF X-RAY SCATTERING

摘要

Radiation detecting apparatus comprising a collimator and a detector, the collimator comprising a material for blocking radiation and a region that is a sector of an annulus or a plurality of regions in a configuration in the shape of a sector of an annulus for allowing transmission of said radiation, the detector being spaced a distance from the collimator such that when a radiation source and sample comprising a crystal material, are positioned at suitable positions the radiation is collimated by the collimator and contacts the sample a predetermined distance from the detector at a plurality of locations corresponding to the region or regions of the collimator, and the Bragg diffracted radiation from the crystal material at two or more and preferably all of the plurality of locations overlap at the detector.
