The overall objective of the Phase II effort is to further investigate the generations of RF emissions from the detonation of high explosives and how those signatures maybe used to further understand the complex interactions within an event as well as the physics responsible for their generation. To accomplish this objective, IS4S will conduct an optimized series of experiments based on the lesson ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is crucial to detect proliferation of nuclear material. Critical challenges include: (a) high sensitivity detection of signature emissions from radioactive isotopes, and (b) cost-effectiveness for deployment of sensor networks across large storage facil ...

Future high-performance integrated circuits in DoD satellite systems will require silicon-on-insulator (SOI) and non-planar nano-technology devices, such as MultiGate Field Effect Transistors (MuGFETs) or FinFETs, which can decrease pattern area of logic circuits below 50% of the conventional planar technologies. However, the single-event-effect (SEE) response of non-planar devices and circuits is ...

Current offensive solutions to neutralize chem/bio agent facilities rely on blast and/or short-burst high-temperature neutralization but have the potential to produce severe collateral damage via agent release. Our team proposes the Dispersed Energetics Coupled for Optimized Neutralization (DECON) Concept, an alternative concept to perform bulk neutralization of agents. The DECON concept can be ...

For applications in DoD satellite systems, devices based on novel nanomaterials offer significant advantages over traditional technologies in terms of light-weight and efficiency. Examples of such novel devices include quantum dot (QD) based solar cells, photodetectors, radars and sensors. However, the response of these devices to radiation effects is not well understood, and radiation effects mod ...

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 ...

We propose to develop a forward-deployable, three-dimensional visualization capability suitable for incorporation into web-based, next-generation consequence assessment models, such as the Joint Effects Model (JEM) and the Integrated Weapons of Mass Destruction Toolset (IWMDT). The thin-interface, web-based, image-server visualization model will enable more informed decisions by the consequence as ...

Strategic DoD satellite and missile systems (Space Based Radar, Space Tracking Surveillance Systems) operate in harsh radiation environments, and will be increasingly based on novel sub-100-nm semiconductor technologies and highly complex circuits. To ensure interruption-free operation, accurate prediction of the radiation response of these technologies and circuits is critical. Predictive calcula ...

We propose to improve the accuracy and capability of Numerical Weather Prediction (NWP) and Atmospheric Transport and Dispersion (ATD) models by performing a tight, downscale/upscale coupling of a community NWP forecasting system, WRF, with a special purpose, urban-to-microscale Computational Fluid Dynamics (CFD) model. This new capability addresses “bridging the gap” between the mesoscale and ...

Magneto-Thermal MRAM uses both heat and magnetic field (current)to overcome thermal instabilities of very small memory cells. Self-generated heat in the cell raises the temperature of magnetic material in the cell above the exchange ordering temperature of the magnetic material (either ferromagnetic or anti-ferromagnetic). Magneto-Thermal MRAM is compatible with advances in photolithography down t ...
