    Transmission electron microscopy and atomic force microscopy analysis of Nb-Al-AlOx-Nb superconducting tunnel junction detectors (1995)

    Notes: The performance of photon detectors based on superconducting tunnel junctions are related to their current - voltage (I-V) curve characteristics and, ultimately, to the quality of the thin tunnel barriers (of order 1 nm) which separate the two superconducting thin films. Both the optimization of the spectroscopic performance of these detectors and the development of a reproducible and high yield fabrication route, require a better understanding of barrier quality and growth techniques. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) provide valuable tools for the investigation of the barrier region and for the control of the quality of the different thin films and related interfaces. In this paper, the results of a TEM and AFM evaluation of Nb-Al-AlOx-Nb tunnel junctions are reported, together with their interpretation on the basis of the I-V curve performance at low temperature (T≥0.3 K). Thickness disuniformities of the Al plus AlOx overlayer and evidence of barrier defects have been found, which may place constraints on the spectroscopic performance of such devices. Through the use of TEM it has also been possible to confirm the epitaxial nature of the Nb base electrode. The junction counter electrode however appears to be polycrystalline, with a columnar morphology and an average grain width of 40 nm. The overall structure of the various layers may well place constraints on the tunneling characteristics of the device. © 1995 American Institute of Physics.

    Propofol for long-term sedation in the intensive care unit A comparison with papaveretum and midazolam (1990)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Thirty-seven patients with a wide range of illnesses were studied during mechanical ventilation of the lungs in an intensive care unit. Fifteen were sedated with a continuous propofol infusion, with analgesia provided by bolus doses of papaveretum. Twelve received a continuous infusion of papaveretum, supplemented by bolus doses of midazolam. The level of sedation was assessed every four hours and measurements were made of haemodynamic and respiratory variables. Levels of sedation were generally satisfactory in both groups. Six patients who received propofol required the use of muscle relaxants, because of their strong respiratory drives, to achieve synchronisation with the ventilator. There was no significant difference in respiratory or haemodynamic variables between the groups, but several patients required inotropic support because of their disease. There was no evidence of inhibition of adrenal steroidogenesis in the propofol group. Propofol can be a useful sedative agent in the intensive care unit, but sedative regimens should be tailored to individual patient requirements.

    X-ray characteristics of a niobium superconducting tunnel junction with a highly transmissive tunnel barrier (1993)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 73 (1993), S. 5098-5104

    Notes: The results of an investigation into the x-ray properties of a superconducting tunnel junction (STJ) are presented. The photoabsorption of an x-ray photon by one of the thin superconducting films of the junction results in the production of quasiparticles, which may subsequently tunnel through the thin oxide barrier into the second superconducting film. The transfer of charge across the barrier is detected, and gives a measure of both the x-ray photon energy and the effective energy gap ε of the superconducting film in which the photoabsorption occurred. A charge output of 55% of the theoretical maximum has been obtained for a niobium-based STJ. Such a charge output indicates a mean energy ε of (approximately-equal-to)4.7 meV is required to create a single charge carrier in the junction such that ε/Δ(approximately-equal-to)3, where 2Δ is the junction energy gap. This is the lowest value of ε/Δ obtained to date for x-ray photoabsorption in STJs. The energy resolution of the device is, however, still poor, with a full width half maximum of (approximately-equal-to)200 eV for 6 keV x rays, compared with the theoretical Fano limited resolution of (approximately-equal-to)4 eV. The principle mechanisms which are believed to degrade the resolution are discussed. These are principally quasiparticle recombination, phonon leakage out of the junction, quasiparticle diffusion into and out of the tunneling region, in addition to possible local variations in the energy gap. A Monte Carlo simulation of the nonequilibrium system has been performed. The results assist in the identification of the major charge loss mechanisms, and indicate various means by which Fano limited resolution may be obtained.

    The dependence of the dissipation on rotation (1993)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 5 (1993), S. 2304-2305 
    Details
    ISSN: 1089-7666

    Topics: Physics
    Notes: A form of the evolution equation for the dissipation showing the effects of rotation is derived directly from the Navier–Stokes equations. Rotation affects the dissipation if the flow is inhomogeneous or compressible. This is due to the fact that pressure scales with inverse Rossby number and certain pressure correlations usually neglected have to be retained when Re Ro≈1. The term reflecting the effects of rotation on the dissipation is a volume integral of the two-point velocity correlation similar in structure to the "rapid-pressure'' correlation appearing in the second-moment equations. Some of its properties are indicated.
