The Beamline Technical Support Group (BTS) at the Advanced Photon Source (APS) has developed two CCD detector systems (the Single and Quad Platinum systems), for X-ray diffraction and imaging experiments. Both of these systems, optimized for sensitivity toward X-ray photons, utilize the Kodak KAF-4320E CCD coupled to fiber-optic tapers, custom mechanical hardware, electronics, and software systems developed at the APS. Each CCD is composed of ~ 2k Ã 2k 25-Â¿m-sized pixels, providing a total active detector area of 168 mm Ã 168 mm. In fast mode with 4 Ã 4 binning, the Quad system can reach a rate of 5 frames per second (fps). The sensitivity of the detector has been enhanced by using tapers with low demagnification ratio (1.78) and CCDs with high quantum efficiency. The sensitivity, resolution, and dynamic range have made the detectors suitable for a wide range of synchrotron experiment, in particular, small-angle x-ray scattering (SAXS). SAXS data from the x-ray scattering of silver behenate powder have been used to demonstrate the performance of the detector.
