Quality Control of High Performance Superconductor Tapes
A superconductor tape and method for manufacturing, measuring, monitoring, and controlling same are disclosed. Embodiments are directed to a superconductor tape which includes a superconductor film overlying a buffer layer which overlies a substrate. In one embodiment, the superconductor film is defined as having a c-axis lattice constant higher than 11.74 Angstroms. In another embodiment, the superconductor film comprises BaMO.sub.3, where M=Zr, Sn, Ta, Nb, Hf, or Ce, and which has a (101) peak of BaMO.sub.3 elongated along an axis that is between 60° to 90° from an axis of the (001) peaks of the superconductor film. These and other embodiments achieve well-aligned nanocolumnar defects and thus a high lift factor, which can result in superior critical current performance of the tape in, for example, high magnetic fields.

SUPERCONDUCTING NANOWIRE SINGLE-PHOTON DETECTOR, AND A METHOD FOR OBTAINING SUCH DETECTOR
The present invention relates to a superconducting nanowire single-photon detector, which can include a superconducting nanowire configured and arranged for the incidence of a photon on a region thereof and the formation, on that region, of a localized non-superconducting region or hotspot.
The superconducting nanowire is made of a high-Tc cuprate superconductor material having a superconducting critical temperature above 77 K.
The present invention also relates to a method for obtaining the superconducting nanowire single-photon detector of the present invention.
High temperature superconducting films and methods for modifying and creating same
Operational characteristics of an high temperature superconducting (HTS) film comprised of an HTS material may be improved by depositing a modifying material onto appropriate surfaces of the HTS film to create a modified HTS film. In some implementations of the invention, the HTS film may be in the form of a c-film. In some implementations of the invention, the HTS film may be in the form of an a-b film, an a-film or a b-film. The modified HTS film has improved operational characteristics over the HTS film alone or without the modifying material. Such operational characteristics may include operating in a superconducting state at increased temperatures, carrying additional electrical charge, operating with improved magnetic properties, operating with improved mechanic properties or other improved operational characteristics. In some implementations of the invention, the HTS material is a mixed-valence copper-oxide perovskite, such as, but not limited to YBCO. In some implementations of the invention, the modifying material is a conductive material that bonds easily to oxygen, such as, but not limited to, chromium.
Equipment for manufacturing ceramic wires
Equipment for manufacturing ceramic wires is disclosed. The manufacturing equipment can comprise a deposition unit for depositing the ceramic wire on a wire substrate, a loading/unloading unit having a release reel for providing the wire substrate to the deposition unit and a coiling reel for discharging the wire substrate from the deposition unit, and at least one buffer unit arranged between the loading/unloading unit and the deposition unit. The buffer unit may continuously be providing the wire substrate to the deposition unit or continuously winding the wire substrate from the deposition unit when the release reel or the coiling reel is replaced.
