![]() The Kβ filter can go here, in a special adapter, if for some reason it can’t go on the receiving end of the optical system. It also houses replaceable slits (10, 5, 2 mm), which determine the X-ray illumination height (spot size perpendicular to the goniometer plane). This slit is set in software, and is constant for each run (it can’t be continuously narrowed at lower 2Θ angles, as far as I know).

It contains the computer-controlled incident slit, which determines the X-ray illumination width (spot size parallel to the goniometer plane, left-right). There are two primary optical modes that diffractometers can be configured in: BraggBrentano optics and Parallel Beam optics. IPS is the incident parallel slit adapter, typically used for a Soller slit. There is also a special SA slit for small angle scattering work. The Bragg-Brentano divergent beam is selected with the BB slit (labeled BB), and the parallel beam with the PB slit. In these geometries the detector and source are located at the intersection points of the goniometer circle (fixed radius) and the focusing circle, whose radius. microstructure components from which maximum depth can affect the information evaluated from the acquired diffraction pattern, are scarce in the scientific literature. The most common goniometer geometries are the so-called BraggBrentano geometry with a fixed sample or 2 geometry with a fixed X-ray tube (Mittemeijer & Welzel, 2013 ). ![]() However, experimental evidence concerning its significant information depth, i.e. The CBO box (cross-beam optics) allows you to switch between a divergent “Bragg-Brentano” X-ray beam, and a parallel X-ray beam, focused using a parabolic, multi-layer mirror. X-ray diffraction in the Bragg-Brentano configuration (XRD) is a very established method. There’s nothing to do there but watch the lights change as the shutter opens or closes. ![]()
