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 ...

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 ...

Robust Chip proposes to develop a unique, new technique to couple circuit simulation and numerical device simulation, for efficient, flexible, and accurate simulation of transient radiation effects at the circuit level. The technique provides the accuracy and flexibility of numerical device simulation for the mobile charge in a semiconductor substrate, combined with the accuracy and speed of compa ...

Radiation-effects modeling community has experienced a growing need for mixed-mode simulation capabilities when analyzing advanced semiconductor technologies. Space Micro Inc. and Silvaco International have worked closely to enable and test radiation-effects modeling capabilities in Silvaco's TCAD simulation framework in the past. This simulation framework also includes 2D- and 3D-mixed mode simul ...

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 ...

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 ...

DTRA operates a suite of high-resolution forecast models for use in atmospheric dispersion prediction. A major problem has been the inability of traditional validation metrics to support the subjective consensus that higher resolution models provide greater skill than coarser models. We believe that the skill scores used over the past 40 years are ill-suited to validating solutions with significan ...

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 ...

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 (

An interactive application that employs social interactions to teach key social conventions, including appropriate responses, reacting to body language and facial expressions, and the ability to ask for help to facilitate functioning in society
