Defense Electronics Corporation (DEC) proposes an innovative radiation hardened by design (RHBD) and reliability improvement solution for silicon, III-V compounds (e.g. SiGe, SiC, GaN, InP, GaAs,), carbon nanotubes (CNT), and graphene. The method is based on analyzing chip-partitioned quiescent current signatures associated with failure modes common to these process technologies. Furthermore, the ...

Kinetic penetrators are currently made of depleted alloys of uranium or tungsten, which are both toxic heavy metals that are harmful to human health and the environment. Amorphous metals have the high strength, fracture toughness and surface erosion resistance needed to replace uranium and tungsten without sacrificing performance. Recent research on amorphous metals has developed bulk metallic gla ...

The development of a high-shock data recorder for use in projectile penetration and pyrotechnic environments is critical to understanding the loads that warhead systems are exposed to in tactical applications. Data from recorders mounted inside warheads can be used by researchers to measure loads on the warhead, fuze, and explosive fill components as well as validate analytic and computational mo ...

This proposal concerns the detection of Special Nuclear Materials (SNM) by using large networks of small, inexpensive, and robust gamma detectors. These detectors will be deployed where consistent surveillance would be difficult by any other means, like remote mountain trails. The proposal describes a novel gamma detector that is extremely robust and inexpensive. The new scintillation material is ...

In this proposed Phase II program we will build on the successful Phase I program where we for the first time implemented engineered epitaxial layers based on nanostructure technology that were used to harden commercial silicon devices against radiation by minimizing collected photocurrents (electron-hole pairs) via recombination centers where we demonstrated that improved radiation hardness could ...

The Defense Special Weapons Agency (DSWA) has identified a need to improve the radiation hardness of advanced integrated circuit technologies. To be practical, this must be achieved in a cost effective way. This proposal by AET, Inc. directly addresses these concerns. Specifi-cally, this proposal provides a means to achieve significant advance in radiation hardness of large scale integrated cir ...

The nuclear weapons community has traditionally focused on the next generation or level of weapon capability complimented by gathering and analysis of actual test data. Now, with the cessation of actual weapons testing, there is an increased need to use the actual test data in modeling techniques to better understand the phenomenology and potential effects of nuclear weapons. The first phase of ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...

This Small Business Innovation Research Project will determine the advantages and disad-vantages of fibrous/polymeric composite materials over traditional material (steel) for retrofitting key civilian facilities against terrorist bomb attack. Retrofit techniques we will evaluate are: strengthening fully and partially exposed columns with composite wraps or shells, masonry walls with bonded comp ...

Environments created from a nuclear event can have a great impact upon the operation of military forces on the battlefield. It is imperative that the associated nuclear effects are portrayed in an environment such as Dirstributed Interactive Simulation (DIS) so that changes canbe made during the weapon system design process to mitigate nuculear effects. These effectscan be extended to other appl ...
