In response to a DTRA need, Physical Optics Corporation (POC) has developed a new, low-cost Advanced Radiation Detector (ARAD) and a process to produce it. ARAD is based on thallium-doped cesium iodide scintillator, sensitive to gamma and X-ray energies up to 1 MeV with 3% resolution, and fully compatible with existing mass production technologies. In Phase I POC successfully completed the ARAD ...

The key innovation of the proposal is a novel, fast and accurate, algorithm (patent pending) to simulate substrate effects, in particular single event transients (SETs), in semiconductor circuits. This new method opens up a new capability for circuit designers to study a large set of substrate and layout related effects using simulation, helps them to make good choices regarding circuit design and ...

Alameda Applied Sciences Corporation (AASC) proposes to replace the anode posts of a soft x-ray z-pinch with an azimuthally symmetric shell of high density, low atomic number gas. Once ionized, the gas column carries the current and eliminates particulate debris that is otherwise generated by the return rods. The gas shell also absorbs unwanted UV and hence eliminates the first Li foil filter of t ...

DTRA requires reliable X-ray sources to irradiate test objects for customers. One key component of test object irradiation is reliable radiation diagnostics to measure the dose and dose-rate to test objects. Current radiation diagnostics possess unacceptable levels of variation. Alameda Applied Sciences Corp proposes the use of a dense plasma focus device as a flat field X-ray calibration sourc ...

This proposal addresses the need for engineering simulation models, validated through innovative test methods for verification and evaluation of structural integrity following an attack with multiple hazards. The project goals, whose feasibility is to be established under Phase I and accomplished in a Phase II effort are a s follows: • Develop optimal methods for analyzing disproportionate coll ...

In Iraq during the month of December 2005, 47 of the 59 (80%) coalition combat deaths attributed to hostile action were caused by improvised explosive devices (IEDs), in the form of roadside bombs, vehicle borne bombs (VBIEDs) or suicide bombers. Even more ominous than the conventional IED threat is the possibility that terrorists and enemy combatants may employ devices for dispersing chemical, bi ...

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 ...
