SUMMARY: CITIUS: a 17400 frames/s X-ray imaging detector with a linear response of up to 945 Mcps/pixel

DESCRIPTION:You can find the slides of the presentation HERE! Abstract: We report our recent progress in the CITIUS (Charge Integration Type Imaging Unit with high-Speed extended-dynamic-range) detector. It has been developed to overcome the count rate limitation of the current state-of-the-art photon counting detector by introducing novel integrating-type pixels with a size of 72.6 micrometers and a high frame rate of 17.4 kfps [1]. Recently we succeeded in experimentally demonstrating its detecting capability of 945 Mcps/pixel (18 Tcps/cm2) at 10 keV while keeping its single photon sensitivity. In this talk\, we report our development status including the performance evaluation and the on-the-fly data processing with FPGAs. A feasibility study of Bragg CDI was carried out at ESRF last year. At SPring-8\, applications of these detector systems to XPCS\, ptychography\, SAXS & WAXS\, X-ray beam monitors by using spectro-imaging capability\, and fluorescence yield XAFS by using large-area high-count-rate energy resolving detection are in progress. The status of these applications is also reported.
