    US Patent Application US17/252,776
    • Lithium-containing chalcophosphates for thermal neutron detection

    Invention

    This invention introduces a series of lithium-containing semiconductors LiMP2Q6 (M = In, Bi, Sb, As, Al, Ga; Q = S, Se, Te) for detecting thermalized neutrons. Lithium may be enriched lithium-6 or natural lithium. The very high resistivity of this compound allows for large-area detector and higher applied voltage on the compound, allowing for increased efficiency and gamma-ray discrimination.

    Benefits

    This material has the capacity to detect thermal neutrons with improved sensitivity and selectivity (thermal neutrons versus gamma rays) over prior art.

  • Advanced R&D, integration, and commercialization of polymer refractive X-ray optical components
    Intellectual Property Available to License
    US Patent 17/039,624
    • Method of Printing and Implementing Refractive X-Ray Optical Components (ANL-IN-20-070)

    Technology

    Using high-resolution polymerization lithography, this technology enables rapid and cost-efficient printing of refractive X-ray optics, such as phase correctors and compound refractive lenses (CRLs) with a better-than-100 nm printing resolution. These optics have shown a higher quality and better performance than conventional lenses, such as those commercially available Be CRLs. Supported on the small flat substrates, these lenses can be quickly deployed into an X-ray beam delivery system.

    Opportunity & Solution

    To fully utilize DOE’s high coherence of the diffraction-limited X-ray sources, there is an urgent need for a giant leap forward in the manufacturing capabilities of X-ray refractive optics that are required for controllable wavefronts in the applications of coherent-based experiment methods. To meet these goals, Argonne National Laboratory researchers have been developing a customizable strategy to manufacture and deploy polymer-based refractive X-ray optics at synchrotron beamlines.

    Benefits

    • Improve multiple polymerization printing lithography schemes for better lens quality and shape controls.
    • Improve the printing resolution to 20-50 nm.
    • Scale-up the procedure for high-throughput optics fabrication, aiming at a useful lens array set per one to a few hours.
    • Investigate high-energy (>20 kev) and high-coherence applications of printed optics.
    • Design commercialization-ready assembly scheme for stand-alone instrument that allows fast optics alignment and flexible operation to meet various experimental requirements at synchrotron beamlines.
    • Develop a cost-effective transfocator mechanism for rapid lens exchange and replacement.
