A Laboratory Approach Relating Complex Resistivity Observations to Flow and Transport in Saturated and Unsaturated Hydrologic Regimes

Description: Subsurface imaging technology, such as electric resistance tomography (ERT), is rapidly improving as a means for characterizing some soil properties of the near-surface hydrologic regime. While this information can be potentially useful in developing hydrologic models of the subsurface that are required for contaminant transport investigations, an image alone of the subsurface soil regime gives little or no information about how the site will respond to groundwater flow or contaminant transport… more

Statistical Analyses of AY-101 Ultrasonic Measurements of Wall Thickness

Description: Tank AY-101 wall thicknesses have been measured using ultrasonic (UT) images. Interest is in using the available data to estimate a worst-case minimum wall thickness for regions of the tank that remain unexamined with the UT approach. Each UT image can provide the wall thickness at a very large number of pixels, but only the minimum value for each image is used in this work. Since the data arise in this manner, one of several candidate statistical extreme value distributions should successfully… more

Deterring Asymmetric Threats from Sub-State Actors

Description: Deterrence means preventing another's actions by influencing their decisionmaking process. Nuclear deterrence was successfully accomplished during the Cold War by holding the adversary's valuable assets at risk by targeting them with nuclear weapons, a policy known as mutually assured destruction (MAD). In this case neither player attacks the other, because the ultimate outcome is self-destruction. Deterrence based upon MAD is largely ineffective against sub-state actors who may have few if any… more

Spheromak Impedance and Current Amplification

Description: It is shown that high current amplification can be achieved only by injecting helicity on the timescale for reconnection, {tau}{sub REC}, which determines the effective impedance of the spheromak. An approximate equation for current amplification is: dI{sub TOR}{sup 2}/dt {approx} I{sup 2}/{tau}{sub REC} - I{sub TOR}{sup 2}/{tau}{sub closed} where I is the gun current, I{sub TOR} is the spheromak toroidal current and {tau}{sub CLOSED} is the ohmic decay time of the spheromak. Achieving high cur… more

Small Nuclear Technology and Market Entry

Description: An overview of energy-system projections into the new century leads to the conclusion that nuclear power will play a significant role. How significant a role will be determined by the marketplace. Within the range of nuclear-power technologies available, small nuclear-power plants of innovative design appear to fit the needs of a number of developing nations and states. Under similar financing options used by the airline industry and others, the capital requirement barrier that puts the nuclear… more

Interferometric Diagnosis of Two-Dimensional Plasma Expansion

Description: Recent advances in interferometry has allowed for the characterization of the electron density expansion within a laser produced plasma to within 10 {micro}m of the target surface and over picosecond timescales. This technique employs the high brightness output of the transient gain Ni-like Pd collisional x-ray laser at 14.7 nm to construct an effective moving picture of the two-dimensional (2-D) expansion within the plasma. In this paper we present experimentally measured density profiles from… more

Probing Interactions in Complex Molecular Systems through Ordered Assembly

Description: Emerging from the machinery of epitaxial science and chemical synthesis, is a growing emphasis on development of self-organized systems of complex molecular species. The nature of self-organization in these systems spans the continuum from simple crystallization of large molecules such as dendrimers and proteins, to assembly into large organized networks of nanometer-scale structures such as quantum dots or nanoparticles. In truth, self-organization in complex molecular systems has always been … more

Final Report for LDRD Project ''A New Era of Research in Aerosol/Cloud/Climate Interactions at LLNL''

Description: Observations of global temperature records seem to show less warming than predictions of global warming brought on by increasing concentrations of CO{sub 2} and other greenhouse gases. One of the reasonable explanations for this apparent inconsistency is that the increasing concentrations of anthropogenic aerosols may be partially counteracting the effects of greenhouse gases. Aerosols can scatter or absorb the solar radiation, directly change the planetary albedo. Aerosols, unlike CO{sub 2}, m… more

Multi-keV X-Ray Conversion Efficiency in Laser-Produced Plasmas

Description: X-ray sources are created at the Nova and Omega laser by irradiating a confined volume of Ar, Xe, or Kr gas. The gas is heated by forty 0.35 {micro}m wavelength, 1-ns square laser beams to produce He-like ions that radiate K-shell emission over mm-sized dimensions. The targets are designed to be ''underdense'', meaning that the initial gas density is lower than the critical density of the laser, n{sub c} {approx} 10{sup 21} cm{sup -3}. The laser energy is primarily absorbed by inverse bremsstra… more
