Co-Sponsoring Commission: Crystallography of Materials

Advanced large-area hybrid pixel photon-counting detectors enable high signal-to-noise ratio, high speed, and efficiency in photon detection for various synchrotron and laboratory applications. This provides opportunities to advance photon science, including X-ray diffraction and crystallography, scattering, spectroscopy, and imaging. This microsymposium will highlight efforts aimed at extending the photon detection range from lower energies through active sensors and to higher energies with high-Z materials, with special focus on potential improvements for synchrotron and other lab-based demands. New methods to reduce effective pixel size, minimize stacking, and improve energy resolution through intelligent pixel processing will be discussed. Other emerging development trends include increasing frame rates through higher-bandwidth readouts, improving hybridization processes to reduce gaps, and employing high-throughput, low-delay embedded AI and machine learning to improve real-time frame quality. Recent progress in real use cases will be emphasized.
