The imaging station at BL 10-2 is used to perform rapid imaging on larger samples with larger beam sizes. The sample positioning stage has a total travel limit of 600 mm horizontally and 300 mm vertically. The beam size can be determined by pinhole apertures (50 to 250 microns) or glass capillary (~10 microns). Future upgrades may allow for the installation of a K-B mirror pair to attain beam sizes of ~2-5 microns. BL 10-2 uses a wiggler for the x-ray source and has x-ray fluxes approximately 10-50 times greater than BL 2-3. This provides a complementary set of abilities to be able to scan large areas (also good for survey scans of samples to be measured at higher resolution later at BL 2-3) or detect lower elemental concentrations. BL 10-2 is also capable of performing micro-spectroscopy and spectroscopic imaging.

| Instrumentation | Scattering: Detector, ion chambers, current amplifiers, sample positioners, PMTs 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. |
