ABOUT THE PROJECT

D8 ADVANCE X-ray diffractometer for research in the area of material science - designed for research in the area of research materials and should  execute  minute phase analysis of different materials in a wide range of angles of reflection in the automatic mode.

The D8 ADVANCE is the system of choice when it comes to controlling the micro properties of samples.  With the compact, 360° Eulerian cradle, you can measure your sample in all orientations. PolyCap™ provides the necessary beam intensity on the sample. In a short time, you are able to measure the entire texture and then evaluate the measuring data traditionally or with the component method (MULTEX). D8 ADVANCE even reveals the secrets of finished highly machined items. The result of a sequence of measurements with large diffraction angles is the residual stress. Using this value and the X-ray elastic constants precisely calculated by ELASTIX and the help of DIFFRAC plus, you obtain the precise value of normal stress which plays a decisive role in the physical properties of your work piece. Sample throughput and data quality can significantly be improved by using our V ÅNTEC-1 linear detector. With it’s huge 2 Theta coverage data sets can be collected every second using the unique Snap-Shot mode.

Since the introduction of X-ray optics for parallel beam geometry, exact positioning of the sample in diffraction plays only a subordinate role thanks to our Göbel Mirror and the PolyCap™ optics. Use the sample mounting which is appropriate. Regardless of whether you require to study unformed samples or objects with uneven surfaces, you will always obtain clear and useful diffractograms. The large central opening in the D8 goniometer even lets you study all areas of very long objects without the need to damage them. Another advantage of using parallel beam optics is the resulting intensity increase. This drastically reduces measuring times during the residual stress analysis, for example. Parallel beam optics puts you in the position to perform analyses which were inconceivable in the past.
