  1. Advanced nanocomposite scintillator for gamma radiation detection

    SBC: AGILTRON, INC.            Topic: DTRA08005

    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 ...

  2. A Novel Cost Effective Method for Growing High Performance Radiation Sensors

    SBC: Radiation Monitoring Devices, Inc.            Topic: DTRA082007

    Certain lanthanide halides have significantly higher light output than NaI:Tl, the comparison standard for scintillators, plus other important properties, including fast decay times and excellent proportionality. Unfortunately, lanthanide halides grown by traditional melt processes have high production costs and limited availability. Crystals are usually limited to about 5x5 cm2, right cylinder, ...

  3. Engineering Models for Damage to Structural Components Subjected to Internal Blast Loading

    SBC: Thornton Tomasetti, Inc.            Topic: DTRA08006

    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 ...

  4. High Fidelity Modeling of Building Collapse with Realistic Visualization of Resulting Damage and Debris

    SBC: Thornton Tomasetti, Inc.            Topic: DTRA082005

    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 ...

  5. Advanced nanocomposite scintillator for gamma radiation detection

    SBC: AGILTRON, INC.            Topic: DTRA08005

    Until now gamma radiation detection has required large single crystals of sensitive materials that are difficult to produce consistently on an industrial scale. In collaboration with a research group at the University of Texas at Arlington, Agiltron proposes to develop a new class of nanocomposite scintillator materials. The radiation detection characteristics of the synthetic nanoparticles in the ...

  6. Improvements in Scintillation Technology for Detection of Nuclear Radiation

    SBC: Radiation Monitoring Devices, Inc.            Topic: DTRA07004

    High-resolution scintillation crystals and crystal arrays are important components of current and future handheld and arrayed detectors (used for DOD/DTRA applications), and scintillation spectrometers (routinely used in high energy physics research, medical imaging, diffraction, homeland security, nuclear waste clean-up, nuclear treaty verification and safeguards, and geological exploration). Un ...

  7. Agent Defeat using a DWA Accelerator

    SBC: Brookhaven Technology Group, Inc.            Topic: DTRA08008

    A new type of compact induction accelerator currently under development at the Lawrence Livermore National Laboratory (LLNL) promises to increase the average accelerating gradient by at least an order of magnitude over that of existing induction machines. The machine is based on the use of high gradient vacuum insulators and advanced dielectric materials and switches. The system, called the Diel ...

  8. Engineering Models for Damage to Structural Components Subjected to Internal Blast Loading

    SBC: Thornton Tomasetti, Inc.            Topic: DTRA08006

    Predicting the response of building components to internal detonations is more complex than the corresponding task for external loads because of the more complex loading waveforms which include multiple reflections in the shock phase followed by a long duration pseudostatic loading that depends upon room venting. Add the possibility of additional impulsive loading from primary debris. We propose t ...

  9. Novel Methods to Measure Penetrator Dynamics in Multi-Layer Geometries

    SBC: Thornton Tomasetti, Inc.            Topic: DTRA07011

    In Phase I of this effort we analyzed the structural response of a BLU 109 during typical penetration events. Based on these finite element results, we proposed and demsonstrated a simple robust concept for a passive penetrator sensor that identifies the material being penetrated and also correlates strongly with its underground trajectory. Such a sensor would obviously provide valuable informatio ...

  10. "Typical day" Meteorological Data for Atmospheric Transport and Dispersion (ATD) Modeling

    SBC: ATMOSPHERIC & ENVIRONMENTAL RESEARCH, INC.            Topic: DTRA06004

    The complexity of Atmospheric Transport and Dispersion (ATD) modeling requires physically consistent weather data evolving in both space and time. Spatially and/or temporally averaged data found in climatological products is not suitable for ATD modeling. The proposed solution for providing “typical day” meteorological data couples innovative search techniques applied to long-range historical ...
