Large X-ray generators using gas fill loads are a key element in the DTRA simulator program. Consistent relative timing between the injection of the gas shell and the generator current pulse is crucial to producing consistent, high-yield x-ray pulses.To that end HY-Tech proposes replacing existing high voltage trigger pin technology, with a sensitive, all fiber-optic heterodyne interferometer ba ...

Nu-Trek will design, fabricate, and demonstrate 23 models of GaAs PCDs. Technical characteristics include 50-500 ps response time, 10E6-10E12 rad(Si)/s dose rate capability, and a spectral range of < 1 keV through several MeV. The GaAs PCDs will be used asdose rate monitors, flux monitors, and as detectors in spectrometers. They will supplement/replace Si PIN diodes (faster, less sensitive), diamo ...

OBJECTIVE: To develop an analytic method to predict fragment characterization and the resulting airblast propagation from the detonation of a cased explosive. Current procedures are heuristic, based on empirical analysis of test data and simplified analytic expressions. While these work satisfactorily for traditional munitions that detonate in conditions similar to the testing arenas, there is co ...

OBJECTIVE: Develop a Forensic DNA Analysis Kit for Genetic Intelligence that can be used on unknown human DNA samples collected from the battlefield to provide information about the individual who deposited the sample, such as potential ethnicity, height, eye color, hair color, age, sex, and/or facial features. The kit should leverage Short Tandem Repeats (STR), Single Nucleotide Polymorphisms (S ...

Robust Chip (RCI) and Vanderbilt University (Vanderbilt) propose a joint project to create and characterize a comprehensive, accurate, single event simulation solution for ultra scaled (45nm, 32nm, and below) CMOS technologies. The project focus is on developing a production strength single event analysis solution for 45nm, 28nm and 22nm CMOS, building on the most advanced single event characteriz ...

Surface detection of specific radioisotopes of the noble gases xenon and argon are essential for detection and discrimination of underground nuclear explosions. We propose a unique combination of numerical modeling and stable isotope release experiments to enhance the predictability of subsurface transport of the noble gases of interest. Our proposed research will identify and quantify the physi ...

ABSTRACT: Metal-oxide devices offer power dissipation advantages such as low standby power dissipation, better defect resilience versus silicon, superior electronic and magnetic properties, and are broadly Si compatible hence their attractiveness and candidacy fo BENEFITS: Radiation hardened microelectronics are critical for future Department of Defense (DoD) systems where devices are required to ...

ABSTRACT: We propose a concept for the detection of radiological sources at stand-off distances, using a two part system consisting of a detector tag and a radar system. A radiation-sensitive resonant circuit with nonlinear properties (the tag) is placed near a kn BENEFITS: Successful completion of this project will result in one or more circuit designs for detection tags, and theoretical, simula ...

The Defense Threat Reduction Agency, DTRA, currently uses technologies capable of detecting IEDs using airborne sensors that are demonstrated as reliable. These systems are only used for detection purposes and are not capable of neutralizing the IED. Due to IEDs being located in remote, dangerous, and hostile locations, there is high casualty risk for personnel to manually neutralize the target by ...

This is a proposal to develop a unique, Ultrashort Pulsed Off-axis Digital Holography (USPODH) system, enabling the high frequency imaging of detailed 3D structures within aerosol fields under harsh thermodynamic conditions and high optical depths where ordinary imaging is essentially useless. Many powerful imaging methods have failed to provide this capability because noise from multiple scatteri ...
