VESPERS beamline is a hard X-ray microprobe beamline at the Canadian Light Source (CLS). It is designed to measure material structure and composition using X-ray diffraction (XRD) and X-ray fluorescence (XRF) spectroscopy. Four widely differing bandwidths, ∼0.01%, ∼1.6%, ∼10%, and fully polychromatic beam, are selectable to simplify the Laue diffraction analysis and to optimize XRF excitation. Also, X-ray absorption spectroscopy (XAS) can be employed using ∼0.01% bandwidth to provide chemical analytical information. Currently, the beamline is in its late commissioning phase. A number of test experiments have been performed to show the Laue XRD, XRF and XAS capabilities of the beamline. Beamline control and data acquisition software have been developed to include the essential functions for user operation. Full user operation starts in 2010. [ABSTRACT FROM AUTHOR]

We present the design and implementation of a high-performance system for processing synchrotron X-ray microdiffraction (XRD) data in IBM InfoSphere Streams on multicore processors. We report the parallel and stream processing techniques that we use to harvest the power of clusters of multicores to analyze hundred of gigabytes of synchrotron XRD data in order to reveal the microtexture of polycrystalline materials. This system provides a high-performance processing kernel to achieve near real-time data analysis of image data from synchrotron experiments. [ABSTRACT FROM AUTHOR]
