Test Results for a High Field (13T) Nb3Sn Dipole

Description: A Nb{sub 3}Sn dipole magnet (D20) has been designed, constructed, and tested at LBNL. Previously, they had reported test results from a hybrid design dipole which contained a similar inner Nb{sub 3}Sn and outer NbTi winding. This paper presents the final assembly characteristics and parameters which will be compared with those of the original magnet design. The actual winding size was determined and a secondary calibration of the assembly pre-load was done by pressure sensitive film. The actual… more

Anomalous U(1) and low-energy physics: the power of D-flatness and holomorphy

Description: In models with an anomalous abelian symmetry broken at a very large scale, we study which requirements to impose on the anomalous charges in order to prevent standard model fields from acquiring large vacuum expectation values. The use of holomorphic invariants to study D-flat directions for the anomalous symmetry, proves to be a very powerful tool. We find that in order to forbid unphysical configurations at that scale, the superpotential must contain many interaction terms, including the usua… more

Highly stable explicit technique for stiff reaction-transport PDEs

Description: The numerical simulation of chemically reacting flows is a topic that has attracted a great deal of current research. At the heart of numerical reactive flow simulations are large sets of coupled, nonlinear partial differential equations (PDEs). Due to the stiffness that is usually present, explicit time differencing schemes are not used despite their inherent simplicity and efficiency on parallel and vector machines, since these schemes require prohibitively small numerical stepsizes. Implicit… more

Regulation of Coal Polymer Degradation by Fungi

Description: Several investigations have demonstrated that oxalate anion secreted by fungi is able to mediate solubilization of Ieonardite, a highly oxidized lignite. During this reporting period, we have used a biomimetic approach to study oxalate mediated solubilization of several Argonne Premium Coals. Results showed that, relative to Ieonardite, oxalate solubilized minimal amounts of these coals. Other studies showed that pH has a dramatic effect on solubilization of Ieonardite by several Lewis bases. I… more

A Nondestructive Test for Aircraft Halon Bottles, the Development of an Acoustic Emission Application

Description: An acoustic emission test for aircraft Halon bottles has been developed in response to a need expressed by the US Airline Industry. During this development many choices had to be made about test methods, procedures and analysis techniques. This paper discusses these choices and how successful they were. The test itself was designed to replace the currently required hydrostatic test for these bottles. The necessary load is applied by heating the sealed bottles. Acoustic emission is monitored, du… more

Simulations of Laser Imprint for Nova Experiments and for Ignition Capsules. Revision 1

Description: In direct drive ICF, nonuniformities in laser illumination seed ripples at the ablation front in a process called ``imprint``. These nonuniformities grow during the capsule implosion and, if initially large enough, can penetrate the capsule shell, impede ignition, or degrade burn. Imprint has been simulated for recent experiments performed on the Nova laser at LLNL examining a variety of beam smoothing conditions. Most used laser intensities similar to the early part of an ignition capsule puls… more

Regional growth and energy supply: Is there an energy security issue?

Description: This study examines how the growth of the developing world might affect energy markets in the future. Based on recent growth trends, world energy demand could reasonably be expected to grow from about 350 Exajoules (EJ: 1.0E18=0.95 Quad) to nearly 1025 EJ by the year 2020, nearly 3x current consumption estimates. Introduction of more energy-efficient technologies could reduce this growth by about 17% to 830 EJ. But one cannot rely exclusively on current trends to forecast future energy demand. … more

Measurement of Gas Transport Properties for Chemical Vapor Infiltration

Description: In the chemical vapor infiltration (CVI) process for fabricating ceramic matrix composites (CMCs), transport of gas phase reactant into the fiber preform is a critical step. The transport can be driven by pressure or by concentration. This report describes methods for measuring this for CVI preforms and partially infiltrated composites. Results are presented for Nicalon fiber cloth layup preforms and composites, Nextel fiber braid preforms and composites, and a Nicalon fiber 3-D weave composite… more

Alternative measures of potential predictability applied to ensemble simulations of seasonal land-surface climate

Description: The potential predictability (PP) of seasonal climate at the land surface is of enormous human import, and therefore merits close investigation. The PP of a seasonal land-surface variable may be defined as the upper bound in mean forecast to be expected when the seasonal state of the oceans is known precisely (as when SST`s are prescribed), but when the initial conditions are known imprecisely. The PP of a seasonal land-surface variable is related to its degree of insensitivity to the choice of… more

Fundamental chemistry and materials science of americium in selected immobilization glasses

Description: We have pursued some of the fundamental chemistry and materials science of Am in 3 glass matrices, two being high-temperature (850 and 1400 C mp) silicate-based glasses and the third a sol-gel glass. Optical spectroscopy was the principal tool. One aspect of this work was to determine the oxidation state exhibited by Am in these matrices, as well as factors that control or may alter this state. A correlation was noted between the oxidation state of the f-elements in the two high-temperature gla… more
