X-ray diffraction and tomography
The Materials Characterization Facility houses several x-ray devices including:
- Panalytical X’Pert Pro MPD X-Ray Diffractometer
The MPD uses focusing optics for analyzing powder and bulk materials. It has a PIXcel detector for rapid scanning. - Panalytical X’Pert Pro MRD X-Ray Diffractometer
The MRD uses lens, mirror and high resolution optics for parallel beam techniques. It is used for thin film analysis, pole figures, stress measurements, in-plane scans, reflectivity, rocking curves and reciprocal space maps. - Malvern Panalytical Empyrean XRD
The Empyrean has focusing optics and parallel beam optics. It is used for powder/bulk XRD analysis, thin film analysis, pole figures, residual stress measurements, reflectivity, rocking curves, microdiffraction, and in situ high temperature work.
- Additional X-Ray Equipment
The Materials Science and Engineering Department also maintains x-ray instruments in laboratories outside the central facility.
- Xenocs Xeuss 3.0 SAXS/WAXS
This instrument supports the development of cutting-edge nanostructured materials that have keys features ranging in size from tens of Angstroms to hundreds of nanometers. To allow in situ and in operando characterization of structural properties, this custom, automated Xenocs Xeuss 3.0 x-ray scattering system enables high-throughput studies at a variety of length scales.

NT-MDT Spectra AFM/Raman
The Spectra has similar AFM capabilities as the Solver and NTEGRA but with the added befit of a confocal Raman spectrometer. The Raman system is outfitted with a 532nm and 633nm laser paired with 4 different gratings. The combined AFM Raman setup allows for tip enhanced Raman (TERS), this allows for an improvement in spatial resolution from hundreds of nanometers to tens of nanometers.
