Gamma radiation detection has traditionally required single crystal materials that are difficult to produce consistently on an industrial scale. Agiltron has developed a new class of scintillator materials based on composites containing nanoparticles. These so-called nanocomposites exhibit radiation detection characteristics superior to currently available single crystal scintillators. In Phase I ...

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 ...

For ultra high-speed, ultra low-power applications in DoD space and weapons systems, devices and circuits fabricated from III–V semiconductor compounds offer significant advantages over silicon-based technology. However, the uncertainty in single-event-effect (SEE) response of compound semiconductor technologies forces the use of empirically-based hardening techniques with penalties in increased ...

More than 52% of U.S. urban highway congestion is a direct result of highway incidents. Federal and State transportation authorities are searching for quick, cost-effective and efficient highway incident detection and warning systems. Several solutions have been proposed but none could satisfy requirements of transportation authorities. Central Signal's research and development, grounded in mor ...

EMC2''s Phase II proposal focuses on continuing development of "Soft Crack Arrestors" through additional key material property, detailed analytical refinement of the design, and full-scale pipe validation testing. This material testing will be done over a range of temperatures to cover extreme conditions for future pipeline designs, with special attention to arctic applications. It is also essen ...

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 ...

Photon-X is proposing to develop a 3D roof imaging system to monitor vehicle roof deformation during vehicle rollover testing. The system will provide photographic resolution imagery with the ability to track the dot pattern on the vehicle roof. The Photon-X spatial phase 3D imaging system will provide an accurate visible record of roof deformation with position accuracy of 1mm and velocity accu ...

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 ...

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 ...

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 ...
