- Offering a number of distinct advantages for materials research, this facility houses a small angle X-Ray scattering system (SAXS), a general area diffraction detection system, 2 powder diffractometers, a back-reflection Laue system, and a high-resolution diffractometer. For most samples, very little sample preparation is needed. All types of materials, including polymers, clays, metals, and ceramics can be analyzed. Samples can be in powdered, single crystal, thin film or bulk form. X-Ray techniques are completely non-destructive.
