Two-dimensional camera for millisecond range time-resolved small- and wide-angle X-ray scattering

A combined small-angle and wide-angle X-ray scattering (SAXS/WAXS) camera has been implemented using area detectors suitable for real time experiments down to millisecond time range. The design is based on the existing high brilliance SAXS camera with a sample-to-detector distance variable from 1 m to 10 m and to which a two-dimensional WAXS detector is coupled. Two independent image intensified CCD detectors allow simultaneous real-time SAXS/WAXS experiments on oriented samples down to the millisecond time range. A wide scattering vector range spanning from 0.001 Å^-1 to 6 Å^-1 is covered by this combined setup. Both detectors have single photon sensitivity and the spatial resolution is about 200 μm. The WAXS detector is mounted at an angle inclined to the primary beam and the process of image transformation into non-arbitrary scattering vector coordinates is demonstrated for a standard p-bromobenzoic acid sample.
