  • Phase Transformations During the Reaction Heat Treatment of Internal Tin Nb _{3} Sn Strands With High Sn Content

    The phase transformations that occur during the reaction heat treatment (HT) of Nb3Sn superconductors depend on the overall elemental composition of the strand subelements. In the case of modern high Jc strands with a relatively low Cu content, liquid phases are present during large temperature intervals and phases that can be detrimental for the microstructural and microchemical...

    This paper studies the theory of traveling-wave photodetection in superconductive multilayer optical waveguides, as a general platform for ultrafast, ultrasensitive, and ultralow-noise optoelectronics. The kinetic inductance theory of superconductive thin films and the modified transmission line theory are employed to investigate the distributed photodetection and signal generation mechanisms in s...

  • Vortex Interaction in Arrays of Fully Coupled Josephson Junctions

    The vortex-vortex interaction energy is analyzed in two-dimensional arrays of Josephson junctions in which the effects of self-induced fields are important. We find that only if all the junctions are coupled by the magnetic inductive fields, the interactions between vortices are similar to the interactions between vortices in thin superconducting films and that approximate inductance models can le...

  • Analytic Estimates of Magnetic Energy in Superconducting Quadrupoles

    Publication Year: 2008, Page(s):1774 - 1780

    In this paper, we propose analytical formulae to determine the magnetic energy stored in superconducting quadrupoles made of sector coils. The study is based on the Fourier transformation of the current density flowing within the coils. The case of real magnets (i.e., magnets which are not made of pure sector coils) is treated and a heuristic corrective coefficient allowing taking into account the... View full abstract»

    The recently developed cryogenic Fourier-transform ion cyclotron resonance mass spectrometer (FTICRMS) has provided an opportunity for improvement in the limit of detection of FTICRMS by cooling the detection preamplifier to 4 K, thus reducing the thermal noise in the preamplifier. In this manuscript, we describe the development of a low-noise cryogenic preamplifier for FTICRMS and its performance... View full abstract»

  • Large-Scale SFQ Switches Using Miniaturized 2 ,\times, 2 Switch Cell

    We have developed a miniaturized 2times2 switch cell, a key component of single-flux-quantum switches. The cell was optimized using a full-custom design approach instead of our conventional cell-based design approach. The cell contains 74 Josephson junctions, and its power consumption is 16.8 muW. Its area is significantly reduced to 160 mum times 200 mum, which is 69% smaller than our conventiona... View full abstract»

  • High-Speed Nb/Nb–Si/Nb Josephson Junctions for Superconductive Digital Electronics

    Josephson junctions with cosputtered amorphous Nb-Si barriers are being developed at NIST for use in voltage standard circuits. These junctions have the potential for a wide range of applications beyond voltage standards because their electrical properties can be tuned by controlling both the composition and the thickness of the barrier. If the composition of the barrier is tuned so that the resis... View full abstract»

    In our prior paper, we reported forming (110)-oriented LaMnO3 on a biaxially textured Ni-3at%W substrate. Chemical analysis of these films subsequent to publishing the paper showed only La and O-there was no Mn present in the film. The film was actually (400)-oriented La2O3 with the cubic bixbyite structure. Subsequent studies also showed that MnO film is not stabl... View full abstract»
