Bruker Energy & Supercon Technologies, Inc. (June 28, 2010)
Bruker Energy & Supercon Technologies, Inc. (BEST) has reported its in-field high magnetic field test
results for its second-generation (2G) HTS tape, confirming an enhanced performance arising from
improvements to its proprietary manufacturing technology. The YBCO material produced by BEST recentlyachieved a new record critical current of 1,925 A in a 4-mm-wide tape tested at a temperature of 4.2 K in an
18-T magnetic field directed parallel to the tape surface. This current corresponds to a 4,810 A per cm-widthand a superconductor current density of 27 MA/cm2. With a perpendicular field orientation, a critical currentof 1,000 A in a 7-T magnetic field and a critical current of 732 A in a 10-T magnetic field were achieved.
These critical current test results were verified in collaboration with the high magnetic field test laboratory at
the Karlsruhe Institute of Technology in Germany. Dr. Alexander Usoskin, an R&D Manager at BEST,
commented, "We believe these new critical current test values are more than twice the highest criticalcurrents previously observed in 4 mm wide HTS coated conductors in such magnetic fields. The results
were obtained from 5 to 10 meter long tapes that we consider to be representative samples of our large
scale YBCO manufacturing process. With our new proprietary deposition technique based on multi-beampulsed laser deposition, the manufacturing of such 'high-field' HTS tapes is now feasible, and we also
expect these processes to be more robust for increasing processing yields." Dr. Klaus Schlenga, Chief
Technology Officer at BEST, added, "These in-field critical current test results are especially impressive
since the high current capacity is accompanied by high intrinsic mechanical tape strength, without the needfor any additional reinforcement, for example with steel tapes. Significantly improved in-field performance
should positively influence high magnetic field applications that are tightly linked to the technical criticalcurrent density of the YBCO superconductor, such as superconducting dipole magnets, Nuclear Magnetic
Resonance (NMR) ultra-high field superconducting magnets, and other new superconducting magnet
designs in energy research."

Quantum Electronics
Raytheon Company (June 22, 2010)
Raytheon BBN Technologies, a wholly owned subsidiary of Raytheon Company, has announced amajor advance in quantum information technology regarding the coupling of light and superconductors.
Under normal conditions, superconducting atoms absorb photons at a particular frequency. A researchgroup at Raytheon, in collaboration with the National Institute of Standards and Technology, has found thatby applying a second field at a different frequency, this absorption can be prevented—making thesuperconducting atom effectively transparent. This discovery suggests the possibility of the efficient
coupling of superconducting quantum bits, also known as qubits. Will Kelly, associate scientist at RaytheonBBN Technologies, commented, "Superconducting artificial atoms offer fast and reliable processing, andlight offers fast and reliable transmission over long distances. Combining light and superconducting artificial
atoms offers the best of both and is a promising development for building a large-scale quantum
computer." The company’s achievements have been reported in Physical Review Letters.

BasicBrookhaven National Laboratory (June 14, 2009)
Researchers at Bar-Ilan University (Israel) and Brookhaven National Laboratory have successfully
fabricated thin films patterned using large arrays of superconducting nanowires and loops. The productionof superconducting nanowires has been difficult, if not impossible, using conventional superconductors
because the minimum size required for these samples to become superconducting is relatively large. In
layered copper-oxide superconductors, however, the coherence length is much smaller; in addition, thesematerials operate at warmer temperatures, making them more attractive for real-world applications. In thepresently reported study, the Brookhaven team used a precision technique (molecular beam epitaxy) tomake superconducting thin films one atomic layer at a time. The Bar-Ilan team then used electron-beamlithography to “etch” a pattern of thousands of loops into the material’s surface. The resulting “nanowires”
were only 25 nanometers in diameter and were 150 – 500-nm long. Measurements of electrical resistanceconfirmed that these nanowires were superconducting at temperatures below about 30 K. Furthermore, theresearchers observed that the electrical resistance of these materials could be altered in an unexpectedmanner by placing them in an external magnetic field. Instead of the loop resistance continuing to increase
when placed within an increasing external magnetic field applied perpendicular to the wires, the loop
resistance oscillated up and down. Ivan Bozovic, a physicist at Brookhaven, commented, "Theseoscillations in resistance have a large amplitude, and their frequency corresponds to discrete units (quanta)of magnetic flux—the measure of the strength of the magnetic field piercing the loops. A material with sucha discrete, switchable form of magneto-resistance—especially from the superconducting to thenon-superconducting state—could be extremely useful for engineering new devices." The group’s work
was published in the online version of Nature Nanotechnology (June 13, 2010).

University of Florida (June 27, 2010)
Researchers at the University of Florida have described precisely how the atomic-level structuralelements of high-temperature superconductors impede electrical current; specifically, they developed amathematical model that explains how grain boundaries separating rows of atoms within superconductors
impede current. The group abstracted a very theoretical model for a single boundary in a manner such thatthe model can be applied to all such boundaries in a high-temperature superconducting wire. While the newmodel does not suggest a way to break down these barriers to electrical current, it should provide
researchers with a better tool for interpreting the results of past and future experiments. The group’s
research was published in the online edition of Nature Physics.
