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 ...

COMPUTER MEMORY ARRAYS ARE EXTREMELY VULNERABLE TO ELECTROMAGNETIC DISTURBANCES RESULTING FROM ACCIDENTAL OR HOSTILE ACTIONS. HARDENING AGAINST SUCH EFFECTS CAN BE IMPARTED EITHER BY ADDING EXTERNAL PROTECTION TO EXISTING SYSTEMS OR BY INCORPORATING SURVIVABILITY IN NEW DESIGNS. INHERENT HARDNESS CAN BE IMPARTED TO RANDOM ACCESS MEMORY ARRAYS BY USING THIN FILM FERROELECTRIC MATERIALS AS MEMORY EL ...

CONVENTIONAL INSTRUMENTATION FOR AIRBLAST PRESSURE MEASUREMENTS IN CAVITY SHOTS IS LIMITED IN RISE TIME CAPABILITY. THIS RESULTS IN THE INSTRUMENTATION PROVIDING AN INCORRECT INDICATION OF PEAK PRESSURE, WHICH CREATES DISTORTION IN GENERATED HEIGHT-OF-BURST CURVES. THE DEVELOPMENT OF A FIBER OPTIC AIRBLAST PRESSURE SENSOR BASED ON THE PHOTOELASTIC EFFECT IS PROPOSED. THIS TECHNIQUE PROMISES TO PRO ...

SIMOX MATERIAL IS RAPIDLY BECOMING THE SOI MATERIAL OF CHOICE FOR MANY IC APPLICATIONS, INCLUDING RADIATION HARDENED. A CONSTANT THEME OF CONCERN THROUGHOUT THE DEVELOPMENT OF THIS TECHNOLOGY HAS BEEN THE METALLIC IMPURITY CONTENT IN THE MATERIAL. MAJOR EFFORTS HAVE ADDRESSED THE ELIMINATION OF THE METALLIC CONTAMINATION BY MODIFICATION OF THE IMPLANTATION EQUIPMENT USED TO FABRICATE SIMOX MATERIA ...

A PROGRAM IS PROPOSED TO EVALUATE THE IMPACT OF CHANNELING OF OXYGEN ON BURIED OXIDE XNTEGRITY IN SIMOX MATERIAL. BURIED OXIDE PINHOLEDENSITY AND CRYSTALLOGRAPHIC ORIENTATION RELATED PATTERNS IN BURIED OXIDE PINHOLE MAPS WILL BE EXPLAINED DEPENDING UPON THE IMPLANT ANGLE. THE METHOD BASED ON THE ELECTROYTIC PLATING OF COPPER WILL BE USED TO OBTAIN THE MAPS OF PINHOLES. THIS WORK WILL IMPROVE KNOWL ...

SIMOX (Separation by Implanted Oxygen) technology achieves total dielectric 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 SO ...

IN THIS PROPOSAL WE OFFER TO DEVELOP FOR THE DEFENSE NUCLEAR AGENCY A SOFTWARE DESIGN FRAMEWORK THAT CAN BE USED BY ALL OF DNA'S CONTRACT ORGANIZATIONS FOR THEIR OWN INDIVIDUALLY TAILORED DNA COMPUTATIONAL SOFTWARE--EXISTING OR DEVELOPMENTAL. THIS FRAMEWORK MAKES USE OF NEWLY DEVELOPED OBJECT-ORIENTED DESIGN AIDES TO ENABLE USERS TO BUILD THEIR OWN CODES FOR USE ON THE NEWEST WORKSTATIONS AND MASS ...
