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 ...

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 ...

The intensity ratio of forbidden-to-allowed transitions in Li and He have been used to determine both turbulent electric fields due to plasma instabilities and quasi-static applied electric fields in low density and temperature plasmas. HY-Tech proposes to extend this technique to the plasma temperatures and densities encountered in plasma radiation sources. In this case uv spectra of Li-like and ...

Intelligent Optical Systems proposes to develop an innovative optical fiber radiation detector whose light trapping efficiency will be greater than an order of magnitude higher than current radiation detectors. Photonic crystal-like optical fibers with novel liquid scintillating cores will be evaluated and tested. These novel photonic crystal light emitting fibers, or PCLEFs, are expected to hav ...

This program will provide an improved understanding of the effects of atmospheric moisture on hazardous material and define methods to better model these effects in the DTRA HPAC model. The work will evaluate the interaction of moisture and hazardous material in the HPAC model based on two levels of coupling the transport equations for hazardous material and moisture. These evaluations will be com ...

Materials and Manufacturing Systems, Inc. (MATSYS) proposes to develop novel reactive structural materials for the enhancement of munitions lethality. This effort will combine our unique expertise in instrumented-Hot Isostatic Pressing (HIP) with new approaches in intermetallic design to develop a new generation of cost-efficient, high strength and reactive composites. The proposed material syst ...

The objective of this proposal is to demonstrate the feasibility of utilizing a three-dimensional spatial display to visualize information from a time-varying hazard prediction model. A spatial 3D display offers true volumetric projections of data and allows observers to gain insight of hazard information that is not possible with conventional 3D graphical scenes on a 2D surface or with presented ...

We propose to develop a novel low-cost digital dosimeter which can be widely used by military, government and professional civilian personnel who work in or may come in contact with radiation sources. The dosimeter will have high sensitivity and multiple operational functions. A custom integrated circuit will be developed to achieve the proposed specifications. It will have long life and automatic ...

The proposed concept has the potential of meeting in full DTRA's Near Term Simulator Goal for a 20-200 keV, 0.03 cal/cm2, 1,000 cm2, < 20 ns FWHM source. Innovations include (1) Parallel Pulse Forming Network for driving low impedance (< 1 ohm) loads; (2) High voltage (300 kV), high current (40 kA), low jitter (< 3 ns), fast rise time (

To address the DTRA need to prevent terrorist nuclear attacks by early identification of radiological dispersal devices (RDD) and improvised nuclear devices (IND), Physical Optics Corporation (POC) proposes to develop a new low-cost large area Advanced Radiation Detector (ARAD), highly sensitive to gamma and X-rays with energies up to 1 MeV. The ARAD is based on NaI(Tl) scintillator and large arr ...
