![]() However, compared to the more quantitative and direct possibilities of collecting diffraction data using the spectrometer developed by his father, the limitations of the Laue-pattern method were very evident to him. Finally, Proto’s software package covers both collection and in-depth analysis, including support for all crystal systems and integration with the Crystallography Open Database (COD). collecting Laue patterns from simple alkali halide crystals and solving their structures. Since the mid-1970s, photographic methods have been. Micro-beam Laue diffraction is a versatile probe for orientation and elastic strain in individual grains of metallic polycrystals. When it comes to orienting the crystal for cutting or quickly scanning the crystal to identify reflections, manual or automated goniometers with chi, phi, and omega rotation are both available to best suit your experimental needs.įor more advanced applications, Proto can create custom saw-cutting adapters that can be utilized in the Laue-COS. Among them the following techniques should be highlighted: Laue, Weissenberg, precession and oscillation. The diffractometer can be configured with either a manual or motorized x,y stage for scanning across a crystal face or orientation mapping. Explains concepts behind Laues experiments and the patterns his team created, and how the Braggs (father and son team) built upon those results to develop w. Equipped with a Proto tungsten x-ray tube, the system delivers on quality and performance, as well as convenient warranty/support options. Flexibility and Safetyīecause it is housed in a large cabinet, the Laue-COS system enables the measurement of large parts and the incorporation of additional accessories while providing full radiation protection for users. An optional transmission camera is also available for weakly diffracting materials. Binning capabilities help ensure quick collection times, making Laue orientation as efficient as possible. With low noise, a pixel size of 64 by 64 microns, and a 150-by-100-mm area, images are produced with incredible quality. The camera is sensitive to a broad range of energies (4-60 keV). It is a small-size program but has convenient and straightforward graphic user interfaces (GUIs), with which one can quickly simulate a complicated Laue pattern only with a few mouse clicks. Python 3 Code and new features are now at: https. The LauePt computer program is an interactive Windows app for simulating white-beam X-ray Laue patterns of general crystals. LaueTools is an open-source project for white beam Laue x-ray microdiffraction data analysis including tools in image processing, peaks searching & indexing, crystal structure solving (orientation & strain) and data & grain mapping visualisation. The system features a back-reflection camera with high quantum efficiency that is made in house by Proto. open source python packages for X-ray MicroLaue Diffraction analysis. Bragg diffraction of plane waves von Laue Crystal diffraction I. Refraction is the change in the direction of a wave due to a change in its speed. Superior Image Quality for Accurate Single-Crystal Orientation A diffraction pattern results from interference of the scattered waves. ![]()
