This Small Business Innovation Research Phase I proposal seeks to develop a low-cost, compact, and rugged gamma-ray spectrometer that could be deployed in large numbers to provide enhanced security from radiological threats. The proposed approach is based on readily available components that are used in conjunction with proprietary designs and electronics to provide unmatched capabilities. The P ...

To address the DTRA need for standoff detection and identification of special nuclear materials (SNM), Physical Optics Corporation (POC) proposes to develop a new Mid-IR Time Domain Spectroscopic Transceiver (MI-TDST) system. The proposed MI-TDST device operation is based on capturing the characteristic signature of molecules in the environment surrounding SNM. Decomposition of these molecules (id ...

Algorithms are needed for fast-running engineering models that predict damage levels of structural members subject to the blast environment from high explosives detonated inside a building (i.e., internal explosions). These algorithms will be used as part of vulnerability analyses that quickly assess building blast damage from internal explosion scenarios associated with terrorist threats, mission ...

For long-range active interrogation of Special Nuclear Materials, an intense beam of mono-energetic directed gamma rays is required. In Phase I of this project, RadiaBeam developed the design for such a source, based on Inverse Compton Scattering (ICS), and determined its feasibility. The key innovation in our source is a novel Interaction Region system design, which significantly increases the av ...

In this proposed Phase II program we will build on the successful Phase I program where we for the first time implemented engineered epitaxial layers based on nanostructure technology that were used to harden commercial silicon devices against radiation by minimizing collected photocurrents (electron-hole pairs) via recombination centers where we demonstrated that improved radiation hardness could ...

Robust Chip Inc. (RCI) and Stanford University (Stanford) propose a project with two main parts: 1. Exploration and development of a combined layout and circuit design methodology for complete protections against both single and multiple single event errors with a minimal circuit and layout overhead. 2. Extension of a unique, combined circuit-substrate, modeling technique for radhard design in ult ...

The objective of this proposal is to develop enabling technologies for the production of bulk scintillating nanocomposites that have the gamma radiation detection properties of single crystal NaI but with the manufacturability of plastic scintillators. These performance criteria may be met by developing nanoparticle polymer composites with ultra-high nanoparticle loadings levels in matrix with a h ...

Detection of chemical and biological warfare agents in a real-world setting is an increasingly urgent problem. Many of the current state-of-the-art sensors are aqueous based and require large biomolecules, such as antibodies, to achieve binding of the target molecule and subsequent reporting of the binding event. These technical hurdles are a drawback when considering deployment of these technol ...

Weidlinger Associates Inc. proposes to develop effective technology for simulating explosive detonations within civil buildings where the propagation of airblast and failure of weak internal walls are strongly coupled. We will conduct a field test program designed to complement other internal detonation testing efforts such as DTRA''s Distinct Cobra, expanding the available database. We will perfo ...

An approach for performing high fidelity modeling for blast and progressive collapse simulations of buildings will be developed. The modeling approach will allow complete simulations of building response to be performed within several days of computing time on desktop PCs. An 'easy to use' modeling interface will also be demonstrated in this effort. All response regimes will be addressed includi ...
