90087S09-II Expanding user demand for X-ray beamline time for science experiments in diverse fields necessitates expensive new beamlines, or the more efficient use of existing resources. Detectors that collect more data, with efficient on-chip and off-chip processing of the resulting data streams, represent the most economical solution to this problem. The innovation is addressing the need for single-photon X-ray detection, combined with high-resolution time stamping, and a dual design for correlation functionality that allows immediate feedback on a region of interest, combined with full-scale data output to a PC for slower, full correlation in software. These functions will allow users to intervene in real time to adjust their experiments, and will increase the volume and precision of collected data, allowing studies over finer distance and time scales. A new time-resolved, correlating X-ray detection instrument was developed for high-throughput, high-sensitivity, time-resolved X-ray scattering and imaging experiments, especially X-ray photon correlation spectroscopy. The event-driven detector is capable of in-pixel single-photon detection and energy discrimination; with the capability to perform multi-channel real time autocorrelation in supporting camera electronics, this represents a major improvement over charge-coupled devices for experiments requiring sub-
