  • Highly charged ion modified oxide device and method of making same
    Patent number: 7914915
    Abstract: A highly charged ion modified device is provided that includes a first metal layer or layers deposited on a substrate and an insulator layer, deposited on the first metal layer, including a plurality of holes therein produced by irradiation thereof with highly charged ions. The metal of a further metal layer, deposited on the insulator layer, fills the plurality of holes in the insulator layer.
    Type: Grant

    Assignee: The United States of America as represented by the Secretary of the Commerce, The National Institutes of Standards and Technology
    Inventors: Joshua M. Pomeroy, Holger Grube, Andrew Perrella, Fern Slew, legal representative
  • Method and apparatus for measuring current density in conductive materials
    Publication number: 20090006015
    Abstract: The present invention relates to an apparatus and method for measuring a current density in a conductive material. The apparatus and method use an algorithm and an extension to the Fourier transform approach that allows transport currents to be treated accurately. Due to its speed, the resulting algorithm is ideally suited for high-resolution and high-throughput magnetic imaging of superconducting tape in real time.

  • Magnetic infrasound sensor
    Patent number: 7134342
    Abstract: A magnetic infrasound sensor is produced by constraining a permanent magnet inside a magnetic potential well above the surface of superconducting material. The magnetic infrasound sensor measures the position or movement of the permanent magnet within the magnetic potential well, and interprets the measurements. Infrasound sources can be located and characterized by combining the measurements from one or more infrasound sensors. The magnetic infrasound sensor can be tuned to match infrasound source types, resulting in better signal-to-noise ratio. The present invention can operate in frequency modulation mode to improve sensitivity and signal-to-noise ratio. In an alternate construction, the superconductor can be levitated over a magnet or magnets. The system can also be driven, so that time resolved perturbations are sensed, resulting in a frequency modulation version with improved sensitivity and signal-to-noise ratio.
