Device modeling and minority carrier lifetime measurements of double heterostructure lifetime specimens indicate that diode conversion efficiency is limited predominantly by interface recombination and photon energy loss to the GaSb substrate and back ohmic contact. Recent improvements to the diode include lattice-matched p-type AlGaAsSb passivating layers with interface recombination velocities less than 100 cm/s and new processing techniques enabling thinned substrates and back surface reflectors. Modeling predictions of these improvements to the diode architecture indicate that conversion efficiencies from 27-30% and {approx}0.85 W/cm{sup 2} could be attained under the above operating temperatures.</p>1.5-GEV FFAG ACCELERATOR AS INJECTOR TO THE BNL-AGS.2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1412726/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1412726/"><img alt="1.5-GEV FFAG ACCELERATOR AS INJECTOR TO THE BNL-AGS." title="1.5-GEV FFAG ACCELERATOR AS INJECTOR TO THE BNL-AGS." src="https://digital.library.unt.edu/ark:/67531/metadc1412726/thumbnail/"/></a></p><p>A 1.5-GeV Fixed-Field Alternating-Gradient (FFAG) proton Accelerator is being studied as a new injector to the Alternating-Gradient Synchrotron (AGS) of Brookhaven National Laboratory (BNL). The major benefit is that it would considerably shorten the overall AGS acceleration cycle, and, consequently, may yield to an improvement of beam stability, intensity and size. The AGS-FFAG will also facilitate the proposed upgrade of the AGS facility toward a 1-MW average proton beam power at the top energy of 28 GeV. This paper describes the FFAG design for acceleration of protons from 400 MeV to 1.5 GeV, with the same circumference of the AGS, and entirely housed in the AGS tunnel.</p>1.5-GeV FFAG Accelerator for the AGS Facility2016-05-19T09:45:19-05:00https://digital.library.unt.edu/ark:/67531/metadc834676/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc834676/"><img alt="1.5-GeV FFAG Accelerator for the AGS Facility" title="1.5-GeV FFAG Accelerator for the AGS Facility" src="https://digital.library.unt.edu/ark:/67531/metadc834676/thumbnail/"/></a></p><p>N/A</p>01-ERD-111 - The Development of Synthetic High Affinity Ligands2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1404716/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1404716/"><img alt="01-ERD-111 - The Development of Synthetic High Affinity Ligands" title="01-ERD-111 - The Development of Synthetic High Affinity Ligands" src="https://digital.library.unt.edu/ark:/67531/metadc1404716/thumbnail/"/></a></p><p>The aim of this project was to develop Synthetic High-Affinity Ligands (SHALs), which bind with high affinity and specificity to proteins of interest for national security and cancer therapy applications. The aim of producing synthetic ligands for sensory devices as an alternative to antibody-based detection assays and therapeutic agents is to overcome the drawbacks associated with antibody-based in next-generation sensors and systems. The focus area of the project was the chemical synthesis of the SHALs. The project concentrated on two different protein targets. (a) The C fragment of tetanus and botulinum toxin, potential biowarfare agents. A SHAL for tetanus or botulinum toxin would be incorporated into a sensory device for the toxins. (b) HLA-DR10, a protein found in high abundance on the surface of Non-Hodgkins Lymphoma. A SHAL specific to a tumor marker, labeled with a radionuclide, would enable the targeted delivery of radiation therapy to metastatic disease. The technical approach used to develop a SHAL for each protein target will be described in more detail below. However, in general, the development of a SHAL requires a combination of computational modeling techniques, modern nuclear magnetic resonance spectroscopy (NMR) and synthetic chemistry.</p>A 1-Joule laser for a 16-fiber injection system2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1412063/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1412063/"><img alt="A 1-Joule laser for a 16-fiber injection system" title="A 1-Joule laser for a 16-fiber injection system" src="https://digital.library.unt.edu/ark:/67531/metadc1412063/thumbnail/"/></a></p><p>A 1-J laser was designed to launch light down 16, multi-mode fibers (400-{micro}m-core dia.). A diffractive-optic splitter was designed in collaboration with Digital Optics Corporation (DOC), and was delivered by DOC. Using this splitter, the energy injected into each fiber varied <1%. The spatial profile out of each fiber was such that there were no ''hot spots,'' a flyer could successfully be launched and a PETN pellet could be initiated. Preliminary designs of the system were driven by system efficiency where a pristine TEM{sub 00} laser beam would be required. The laser is a master oscillator, power amplifier (MOPA) consisting of a 4-mm-dia. Nd:YLF rod in the stable, q-switched oscillator and a 9.5-mm-dia. Nd:YLF rod in the double-passed amplifier. Using a TEM{sub 00} oscillator beam resulted in excellent transmission efficiencies through the fibers at lower energies but proved to be quite unreliable at higher energies, causing premature fiber damage, flyer plate rupture, stimulated Raman scattering (SRS), and stimulated Brillouin scattering (SBS). Upon further investigation, it was found that both temporal and spatial beam formatting of the laser were required to successfully initiate the PETN. Results from the single-mode experiments, including fiber damage, SRS and SBS losses, will be presented. In addition, results showing the improvement that can be obtained by proper laser beam formatting will also be presented.</p>1 Outreach, Education and Domestic Market Enhancement 2 Export Promotion and Assistance2015-12-03T09:30:17-06:00https://digital.library.unt.edu/ark:/67531/metadc783392/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc783392/"><img alt="1 Outreach, Education and Domestic Market Enhancement 2 Export Promotion and Assistance" title="1 Outreach, Education and Domestic Market Enhancement 2 Export Promotion and Assistance" src="https://digital.library.unt.edu/ark:/67531/metadc783392/thumbnail/"/></a></p><p>Geothermal Energy Association supports the US geothermal industry in its efforts to bring more clean geothermal energy on-line throughout the world.

We characterize the beam delivered by the modified injector to the High Current Transport Experiment (HCX) and the effects of finite rise time of the extraction voltage pulse in the diode on the beam head. We demonstrate techniques for mitigating aberrations and reducing beam emittance growth in the injector.</p>$3.6 Million in Savings Identified in AMCAST Assessment (Revised)2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1405012/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1405012/"><img alt="$3.6 Million in Savings Identified in AMCAST Assessment (Revised)" title="$3.6 Million in Savings Identified in AMCAST Assessment (Revised)" src="https://digital.library.unt.edu/ark:/67531/metadc1405012/thumbnail/"/></a></p><p>Summary of AMCAST Industrial Corporation's plant-wide assessment to identify energy and cost saving opportunities at the corporation's facility in Wapakoneta, Ohio.</p>3-D Characterization of the Structure of Paper and Paperboard and Their Application to Optimize Drying and Water Removal Processes and End-Use Applications2016-09-21T02:29:59-05:00https://digital.library.unt.edu/ark:/67531/metadc874564/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc874564/"><img alt="3-D Characterization of the Structure of Paper and Paperboard and Their Application to Optimize Drying and Water Removal Processes and End-Use Applications" title="3-D Characterization of the Structure of Paper and Paperboard and Their Application to Optimize Drying and Water Removal Processes and End-Use Applications" src="https://digital.library.unt.edu/ark:/67531/metadc874564/thumbnail/"/></a></p><p>The three dimensional structure of paper materials plays a critical role in the paper manufacturing process especially via its impact on the transport properties for fluids. Dewatering of the wet web, pressing and drying will benefit from knowledge of the relationships between the web structure and its transport coefficients. The structure of the pore space within a paper sheet is imaged in serial sections using x-ray micro computed tomography. The three dimensional structure is reconstructed from these sections using digital image processing techniques. The structure is then analyzed by measuring traditional descriptors for the pore space such as specific surface area and porosity. A sequence of microtomographs was imaged at approximately 2 m intervals and the three-dimensional pore-fiber structure was reconstructed. The pore size distributions for both in-plane as well as transverse pores were measured. Significant differences in the in-plane (XY) and the transverse directions in pore characteristics are found and may help partly explain the different liquid and vapor transport properties in the in-plane and transverse directions. Results with varying sheet structures compare favorably with conventional mercury intrusion porosimetry data. Interestingly, the transverse pore structure appears to be more open with larger pore size distribution compared to the in plane pore structure. This may help explain the differences in liquid and vapor transport through the in plane and transverse structures during the paper manufacturing process and during end-use application. Comparison of Z-directional structural details of hand sheet and commercially made fine paper samples show a distinct difference in pore size distribution both in the in-plane and transverse direction. Method presented here may provide a useful tool to the papermaker to truly engineer the structure of paper and board tailored to specific end-use applications. The difference in surface structure between the top and bottom sides of the porous material, i.e. "two-sidedness" due to processing and raw material characteristics may lead to differences in end-use performance. The measurements of surface structure characteristics include thickness distribution, surface volume distribution, contact fraction distribution and surface pit distribution. This complements our earlier method to analyze the bulk structure and Z-D structure of porous materials. As one would expect, the surface structure characteristics will be critically dependent on the quality and resolution of the images. This presents a useful tool to characterize and engineer the surface structure of porous materials such as paper and board tailored to specific end-use applications. This will also help troubleshoot problems related to manufacturing and end-use applications. This study attempted to identify the optimal resolution through a comparison between 3D images obtained by monochromatic synchrotron radiation X-CT in phase contrast mode (resolution 1 m) and polychromatic radiation X-CT in absorption mode (res. 5 m). It was found that both resolutions have the ability to show the expected trends when comparing different paper samples. The low resolution technique shows fewer details resulting in lower specific surface area, larger pore channels, characterized as hydraulic radii, and lower tortuosities, where differences between samples and principal directions are more difficult to detect. The disadvantages of the high resolution images are high cost and limited availability of hard x-ray beam time as well as the small size of the sample volumes imaged. The results show that the low resolution images can be used for comparative studies, whereas the high resolution images may be better suited for fundamental research on the paper structure and its influence on paper properties, as one gets more accurate physical measurements. In addition, pore space diffusion model has been developed to simulate simultaneous diffusion in heterogeneous porous materials such as paper containing cellulose fibers and void spaces. Stochastic dynamic approach along with random walk simulation has been implemented to model simultaneous diffusion in 3D matrix of cellulose fibers and pores. This model is suitable for simulating simultaneous diffusion in porous materials under variety of conditions including low relative humidity conditions where diffusion occurs predominantly through one medium i.e. pore space and high humidity conditions where both mediums (i.e. fiber and pore spaces ) are highly conductive. Both pore as well as effective diffusivity values for paper samples of varying structure were compared with the experimental values and are in fair agreement especially through the thickness direction of samples. In addition to this, intrinsic fiber phase diffusivity has been estimated for the first time using a combination of simulation and experimental data.</p>3-D Combinatorial Geometry in the MERCURY Monte Carlo Particle Transport Code2019-01-23T12:54:46-06:00https://digital.library.unt.edu/ark:/67531/metadc1410204/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1410204/"><img alt="3-D Combinatorial Geometry in the MERCURY Monte Carlo Particle Transport Code" title="3-D Combinatorial Geometry in the MERCURY Monte Carlo Particle Transport Code" src="https://digital.library.unt.edu/ark:/67531/metadc1410204/thumbnail/"/></a></p><p>Lawrence Livermore National Laboratory is in the process of developing a new Monte Carlo Particle Transport code named MERCURY.
