Bruker D8 Discover diffractometer

Donald Savage

Ideally suited for rapid phase identification, stress analysis, and texture determination.  It also has mapping capabilities of ~0.1 mm lateral resolution and can be configured for small angle x-ray scattering (SAX).


Source and detector mounted are in a theta-theta geometry allowing easy measurement of powders.
