  • This invention is a new method of fabricating concave/convex optics in which a singlestructure crystal wafer will undergo curvature due to forces created by vacuum rather than the standard compressive techniques.
    Intellectual Property Available to License
    US Patent 8,557,149
    • System and method for implementing enhanced optics fabrication

    This method attempts to reduce the amount of residual stress and aberration that occurs by eliminating the forceful bending of such standard devices. This invention solves a difficult problem faced by those wishing to create a crystal surface, with even modest curvature, without causing non-uniform residual surface stresses.

  • Method to characterize nanofiber assemblies from images
    Intellectual Property Available to License

    US Patent 9,639,926 B1
    • Image processing tool for automatic feature recognition and quantification

    A system for defining structures within an image is described. The system includes reading of an input file, preprocessing the input file while preserving metadata such as scale information and then detecting features of the input file. In one version the detection first uses an edge detector followed by identification of features using a Hough transform. The output of the process is identified elements within the image.

  • A high-resolution, active-optic X-ray fluorescence analyzer combining a large acceptance solid angle with wide energy tunability
    Intellectual Property Available to License
    US Patent 8,130,902B2
    • High-Resolution, Active-Optic X-Ray Fluorescence Analyzer (IN-06-085)

    Active optics apparatus and method for aligning active optics are provided for a high-resolution, active optic fluorescence analyzer combining a large acceptance solid angle with wide energy tunability. A plurality of rows of correctors selectively controlled to bend an elongated strip of single crystal material like Si (400) into substantially any precisely defined shape. A pair of pushers engages opposite ends of the silicon crystal strip exert only a force along the long axis of the crystal strip, and does not induce additional bending moments which would result in a torsion of the crystal.

  • A method to fabricate dielectric capacitors with increased capacitance and durability that can boost the capability of power electronics.
    Intellectual Property Available to License

    US Patent 9,646,766 B2
    • Method of making dielectric capacitors with increased dielectric breakdown strength (IN-10-096)

    The invention is directed to a process for making a dielectric ceramic film capacitor and the ceramic dielectric laminated capacitor formed therefrom, the dielectric ceramic film capacitors having increased dielectric breakdown strength. The invention increases breakdown strength by embedding a conductive oxide layer between electrode layers within the dielectric layer of the capacitors. The conductive oxide layer redistributes and dissipates charge, thus mitigating charge concentration and micro fractures formed within the dielectric by electric fields.

  • Electron-Ion Collider

    Multifaceted effort in the Physics Division to prepare for EIC, collaboration between Medium Energy, Theory and Accelerator groups, together with HEP and MSD.
  • Set of highly precise, specially designed conical springs to control positioning of magnets in undulators for synchrotron radiation and free electron laser applications
    Intellectual Property Available to License

    US Patent 9,355,767 B2
    • Undulator with dynamic compensation of magnetic forces (IN-14-042)

    A method and apparatus for implementing dynamic compensation of magnetic forces for undulators are provided. An undulator includes a respective set of magnet arrays, each attached to a strongback, and placed on horizontal slides and positioned parallel relative to each other with a predetermined gap. Magnetic forces are compensated by a set of compensation springs placed along the strongback. The compensation springs are conical springs having exponential-force characteristics that substantially match undulator magnetic forces independently of the predetermined gap. The conical springs are positioned along the length of the magnets.
