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:ABSTRACT: Due to the high cost and long lead time of space based thermal management systems, there is an increased need for a space qualified thermal network system which can maintain critical components within an acceptable range during operation. SA Photonics has developed an updated design of… more

SA Photonics will be teaming with world renowned experts from its university partners for the… 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:SARA proposes an innovate approach to develop an all solid-state, frequency-agile high power radio frequency (HPRF) source. The approach combines three primary elements: a laser triggered semiconductor switch, a blumlein modulator, and a non-linear transmission line (NLTL). The proposed approach… more
Abstract:SARA proposes a family of innovative broadband, low-profile, and potentially surface-conformal antennas especially-applicable to newly-emerging frequency-agile or waveform-agile HPRF sources. The proposed antennas are notable for their non-resonant characteristics and transmission-line fed, high… more
Abstract:ABSTRACT: Space Micro proposes to mitigate key technology risks to enable development of future satellite communication architectures using W-band (for uplink) and V-band (for downlink). An innovative approach to enable a very wideband modem for W/V band MILSATCOM applications is described and a… more

Abstract:During Phase I of this ONR-funded effort, we made substantial progress toward the overarching goal of improving intuitive decision making in a variety of settings. In that effort we recognized an opportunity to inform the intuitive system by expanding the set of decision attributes that are… more
Abstract:Landing a piloted helicopter such as the SH-60R on the moving deck of a small ship currently requires close cooperation between the pilot, copilot, Landing Safety Officer (LSO), and the onboard Sensor Operator (for RAST/free deck recoveries). This critical task is resource-intensive and can be… more
Abstract:Energetic materials find applications in diverse areas that affect our everyday lives. Their handling is inherently risky, and accidents have been reported that has led to the loss of lives or severe injuries to the people involved. Consequences of accidents for humans and national security make… more
Abstract:ABSTRACT: The proposed project will enable the realization of a low size, weight, & power directional antenna for CDL. A preliminary design of such a system was shown in the Phase I SBIR.

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.
