摘要:
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.
摘要:
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.
