Patents by Inventor Lindsay T. Sexton

Lindsay T. Sexton has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Photonic crystal scintillators and methods of manufacture
    Patent number: 9103921
    Abstract: Photonic crystal scintillators and their methods of manufacture are provided. Exemplary methods of manufacture include using a highly-ordered porous anodic alumina membrane as a pattern transfer mask for either the etching of underlying material or for the deposition of additional material onto the surface of a scintillator. Exemplary detectors utilizing such photonic crystal scintillators are also provided.
    Type: Grant
    Filed: September 24, 2013
    Date of Patent: August 11, 2015
    Assignee: Savannah River Nuclear Solutions, LLC
    Inventors: Ricardo D. Torres, Lindsay T. Sexton, Roderick E. Fuentes, José Cortes-Concepción
  • Nano structural anodes for radiation detectors
    Patent number: 9075148
    Abstract: Anodes for proportional radiation counters and a process of making the anodes is provided. The nano-sized anodes when present within an anode array provide: significantly higher detection efficiencies due to the inherently higher electric field, are amenable to miniaturization, have low power requirements, and exhibit a small electromagnetic field signal. The nano-sized anodes with the incorporation of neutron absorbing elements (e.g., 10B) allow the use of neutron detectors that do not use 3He.
