Abstract:Mobile Non-Intrusive Inspection (NII) systems are advantageous as they can be deployed to where the greatest need exists, and they generally have
small footprints, which is necessary in many locations. However the currently deployed mobile NII systems do not offer effective material
Abstract:Accurate quantitative characterization of materials is crucial for a wide range of industrial and research applications. New transmission scanning electron microscopy (t-SEM) methods have the potential for high-resolution imaging similar to transmission electron microscopy (TEM) with a less… more
Abstract:Collinear wakefield accelerator approaches are limited to transformer ratios of less than two for symmetric drive bunch profiles. Exceeding this limitation is necessary to establish dielectric or plasma wakefield accelerator research as a viable technology for future, compact, high-gradient… more
Abstract:Nuclear resonance fluorescence (NRF) is a promising active interrogation technique for nuclear plants, processing facilities, and spent nuclear fuel storage facilities that can provide detailed information about the nuclear structure of interrogated materials. The samples are exposed to gamma rays… more
Abstract:Conventional linear lattice accelerator designs limit the available dynamic aperture because they are unstable to chromatic effects and subject to resonances. By designing a lattice that is non- linear from the initial design, so-called integrable optics, the dynamic aperture can be increased as… more
Abstract:Present day simulation tools for the accelerator community have a narrow focus on specific problems and have unwieldy command-line driven inputs. In addition, to produce relevant results, the output from one program has to be fed into another, increasing the possibility of errors in translation… more
Abstract:Hybrid laser-plasma accelerator schemes are emerging as tools capable of producing high-energy electron beams as drivers for advanced light sources. However, drastic improvements in beam quality and shot-to-shot stability are needed to establish these schemes for widespread use. RadiaBeam… more
Abstract:Experimental measurement of Normal Zone Propagation (NZP) velocity in HTS 2G wires yields values below 1 mm/s. Such low propagation velocity results in concentrated energy dissipation and irreversible damage of the magnet during an unprotected quench. This project is developing a novel method for… more
Abstract:Present day photoinjector cathodes have poor lifetime or inadequate quantum efficiency for advanced applications. In addition, the efficiency is constrained by the frequency up-conversion in the drive laser from infrared to ultraviolet photons. Novel nanofabrication techniques allow for the… more
Abstract:Ultrashort pulse lasers have unique interactions with matter that include the ability to athermally ablate materials, create micron resolution texturing of surfaces, and provide diagnostic, sensing, and imaging capabilities. Of particular interest to the Navy is the potential use of ultrafast lasers… more
Abstract:Cloud computing virtualizes the presence of servers, software, and data, and makes them accessible to users on demand. By abstracting the details of how the resources are stored, consumers no longer need the expertise or the control over the technology infrastructure. The consumer reaps many… more
Abstract:Modern science and High-Energy Physics in particular, use scientific workflows to collect and analyze extremely large data sets using high-performance data acquisitions systems. As the requirements for scientific data processing systems continue to grow, fundamentally new approaches must be… more
Abstract:Condition-based Maintenance (CBM) of the Littoral Combat Ship (LCS) assets is preferred over the scheduled maintenance because CBM provides a window into the future of the asset"s performance and enables service only when needed. The asset performance indicators captured on both LCS variants… more
Abstract:RTI proposes the development of a unified, open, modular, comprehensive recording platform capable of recording quantitative and qualitative data in a distributed system. The platform will support operational data recording in a distributed system, providing tools for real-time data analysis,… more
Abstract:Forward closure systems must protect submarine missiles from the surrounding underwater environment during storage, and allow for unabated missile egress during launch. The goal of this program is to design a fully reusable, composite forward closure system for use on submarine launch canisters that… more
Abstract:ABSTRACT: To meet the goals of future generation of ELVs, significant improvements must be made in cost. Current expendable launch vehicles are designed using an optimum performance methodology. Recent studies and technology demonstrations suggest that designing to minimum cost may have life cycle… more
Abstract:SARA proposes an innovate approach to develop an all solid-state, frequency-agile high power radio frequency (HPRF) source.

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
