Bruker Single Crystal Diffractometer

Instrument types

The Bruker General Area Detector Diffraction System (GADDS) instrument permits simultaneous collection of diffraction data over a 2theta range as large as 30 degrees and a chi (tilt) range as large as 30 degrees. Combines a Eulerian cradle, which permits many unique tilts and rotations of the sample, with a very fast two-dimensional area detector. This configuration makes this instrument ideal for texture and stress measurements, as well as traditional XRPD and limited SCD and GIXD. A selectable collimator, which conditions the X-ray beam to a spot with a size from 0.5mm to 0.05mm diameter, combined with a motorized x-y stage permits micro-diffraction for multiple select areas of a sample or mapping across a sample's surface. Samples can include thin films on wafers or dense pieces up to 6" in diameter (maximum thickness of 3 mm), powders in top-loaded sample holders or in capillaries, dense pieces up to 60mm x 50mm x 15mm (and maybe even larger). In addition, the GADDS system can collect basic WAXS, SAXS, and GISAXS data by configuring the instrument with a collimator-mounted or detector-mounted beam stop and a helium purged flight tube to reduce air scatter.
