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 ...

Aspen Systems proposes to develop high dielectric constant (K), low loss tellurium polymers to meet the design objectives of high energy density capacitors. In the proposed Phase I program we will apply rigorous computational chemical techniques to predict the properties of this new class of polymers. We will attempt the synthesis of the parent polymer of the tellurium family, fabricate films for ...

The current distribution in plasma radiation sources is both a yardstick for measuring the coupling efficiency of the generator, and a means of studying the implosion dynamics of the load. Since the current distribution cannot be directly measured, it must be deduced from the magnetic field profile. Magnetic field distributions, based on the Faraday rotation of polarized laser light, are typical ...

SIMOX (Separation by IMplanted Oxygen) technology achieves total dielelectric isolation of active device regions from the substrate and reduces the collection path for ionized charges via the built-in buried oxide which restricts charge movement. Advances in SIMOX technology include radiation hardened memories and gate arrays for space applications, ULSI DRAMS for low voltage operation, thin film ...

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...
