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:ABSTRACT: Color coding of symbology can improve operator performance and reduce workload by reducing display clutter and aiding visual search. For example, all"enemy"symbols could be colored red, and all"friendly"symbols colored green allowing the distinction between enemy and… more
Abstract:ABSTRACT: Stereo symbology has promise as a method to help declutter the vast amount of information presented to fighter pilots and to call their attention to important information that may get"lost"among all the other information they are asked to process. Stereo graphics and imagery… more
Abstract:SA Photonics is pleased to propose the development of the SENTRY hyperspectral situational awareness system for the detection of liquid chemical agents in the asymmetric terrorist warfare scenario. SA Photonics will be teaming with world renowned experts from its university partners for the… more
Abstract:Stran of large objects can cause structural fatique, cracks and even structure failure. Therefore, it is important to monitor the strain of large valuable structures to ensure structural integrity. Current hoop strain sensing systems use large number of point sensors such as accelerometers of fiber… more
Abstract:ABSTRACT: SA Photonics SA-HSDO system provides a cost effective way to increase data transfer rate of intercommunication cable links in legacy aircraft where the MIL-STD-1553 buses operate at 1Mb/s.

Abstract:As IEDs increase in complexity and explosive strength, the Army needs a better way to do IED remediation and road repair to enable our convoys to bring troops and supplies to the battlefield. A primary method of dealing with IEDs in roadbeds is to use a bulldozer to remove (and detonate) the IED… more
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.
