  • SYSTEM AND METHOD FOR X-RAY FLUORESCENCE INSPECTION OF LIGHT ELEMENTS
    Publication number: 20260251595
    Abstract: An X-ray fluorescence (XRF) inspection system and method are provided for enhanced detection of light elements in a sample. The system comprises at least one X-ray radiation source configured to emit radiation within a selected energy range, an optical arrangement with one or more reflecting surfaces for filtering and focusing a specific energy band onto an inspection location, and a sample mount for holding the sample. The system is configured to maintain at least one of a vacuum environment or a helium-rich environment along the X-ray path to reduce absorption of low-energy X-rays. In some embodiments, a detector arrangement includes a segmented detector, formed of two or more detection units arranged around the path of the focused radiation, positioned at close proximity to the inspection location. The method includes generating, filtering, and focusing X-ray radiation, providing the controlled environment, and detecting fluorescence emissions for analysis of light elements.

  • Multi-layer horizontal computed tomography (CT) detector array with at least one thin photosensor array layer disposed between at least two scintillator array layers
    Patent number: 9012857
    Abstract: An imaging system (100) includes a radiation sensitive detector array (110). The detector array includes at least two scintillator array layers (116). The detector array further includes at least two corresponding photosensor array layers (114). At least one of the at least two photosensor array layers is located between the at least two scintillator array layers in a direction of incoming radiation. The at least one of the at least two photosensor array layers has a thickness that is less than thirty microns.
