Alameda Applied Sciences Corporation (AASC) proposes to replace the current return rods in the anode of the plasma radiation source (PRS) load, with an annular, supersonic gas jet: an innovation that could drastically reduce source region debris along the line-of-sight (LOS) of the test object, in a z-pinch, soft x-ray, weapons effects simulator, and make the debris mitigation system (DMS) simpler ...

DTRA uses high-resolution mesoscale forecasts to drive HPAC, the DTRA dispersion modeling tool that generates critical forecasts of dosage resulting from releases of chemical, biological, or radiological agents. HPAC is designed to provide probablistic information based on estimates of the uncertainty of the input forecast fields of the meteorological variables (wind, temperature, etc.). ...

U.S. forces working in low-level radiation environments have unsatisfactory choices for monitoring radiation exposure. The currently available A/UDR-13 pocket dosimeter is able to meet sensitivity requirements, but is cost prohibitive at ~$400 per unit, and it fails in the high temperature environments faced our military. Careful monitoring and accurate reporting of the exposed dose will reduce t ...

Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Prevention of the spread of nuclear weapons has reached a state of heightened urgency in recent years, especially since the events on September 11, 2001 and its aftermath. Gamma ray spectrometers are an important tool in checking the proliferation of the nuclear weapons. Important re ...

The Defense Threat Reduction Agency has expressed the need for waterborne transport and dispersion capability to compliment its existing models for Chemical, Biological, Radiological and Nuclear (CBRN) releases. DTRA's current capability is limited to the atmospheric transport of CBRN agents using the HPAC system. The objective of this proposed Phase I study is to couple Applied Science Associat ...

We propose to develop a computational model and associated software library to calculate the transport and dispersion (T&D) of hazardous materials into and through the water. The model is developed for incorporation into HPAC and will compliment its existing atmospheric T&D model for CBRN (including toxic industrial substances) releases. We will investigate existing T&D models including those deve ...

Conventional weapons rely on blast and fragmentation as the primary defeat mechanism, whereas non-energetic payloads rely on other means to defeat the target. Non-energetic weapons may defeat targets by the dispersion of aerosols (solid or liquid) or gases to interact with critical target elements. The objective is to cause some combination of denial, disruption, degradation, or destruction witho ...

We propose to demonstrate the ability to non-evasively probe the characteristics of material properties using acoustical waves through thermal conversion of a remote laser pulse. The advantages of proposed system as an inspection and identification technique are: 1) Non-contact: Sensor does not require contact with container 2) Stand-off: Sensor could be located many meters away from container 3 ...

A visualization package is proposed for the real time visualization of three-dimensional, time-varying hazards data generated by existing and next generation hazard and consequence assessment software. The Hazard Prediction Assessment Capability (HPAC) software will be used as a representative consequence assessment toolset, and the new visualization capability will be integrated in a manner appli ...

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. In order to ensure interruption-free operation, accurate prediction of the radiation response of these technologies and circuits is critical. To addres ...
