Jerome B. Cohen X-ray Diffraction Facility

FUNCTION: The primary function is to provide general-purpose equipment for X-ray scattering and fluorescence studies. The facility can also provide equipment for non-routine experiments such as, special attachments for high temperatures, vacuum or protective atmospheres, monochromators, special linear and area detectors, etc. Examples of current measurements are: powder diffraction (XRD), single-crystal diffraction, thin-film reflectivity (XRR), thin-film diffraction, crystal truncation rod scattering (CTR), small angle scattering (SAXS), Laue diffraction, pole figures, energy dispersive X-ray Fluorescence spectroscopy, x-ray standing waves, high-resolution x-ray diffraction (HRXRD), and grazing incidence wide-angle scattering (GIWAXS), and GISAXS. The X-ray lab also functions to help prepare students and postdocs for their beamtime at the Advanced Photon Source (APS).

EQUIPMENT:There are presently thirteen experimental x-ray stations available, five of which have rotating anode sources.

COMPUTERS AND SOFTWARE:All of the x-ray stations operate via networked PC's with
software that allows for control via stepping motors and data collection via counters. A
networked printer and wireless network are provided. Available software includes: ICDD PDF4+ database, MDI-JADE xrd analysis, CrystalMaker, and Laue diffraction software packages are available. LINUX based SPEC and NEWPLOT (also used at the APS) are available on four of the stations.
