A Huber 6-circle diffractometer is available for high-resolution x-ray scattering research. The six spectrometer degrees of freedom are (q, C, f) for the sample, and (2-q, q-analyzer, q-analyzer) for the detector. Because of high demand, research is confined to problems that can only be addressed with this unique facility. Typical programs involve intrinsically weak scattering systems, such as two-dimensional arrays and high-resolution 3-D problems. Spectroscopy: Ge array detector, LHe cryostat, ion chambers, PIPS detector, optics rail Instrumentation for continous-scanning, large aperture (50-100mm) XAS imaging. |
