Microwave Technologies Incorporated is proposing the development of a very compact radio-frequency (rf) electron beam accelerator which appears to be well-suited for BMDO's directed energy applications. This novel concept employs a single short rf cavity operating in circular polarization to accelerate a low-energy ma ~netized pencil beam to energies that range from 2 to 10 MeV. The proposed accel ...

NON-NUCLEAR APPROACHES ARE SOUGHT FOR HIGH ENERGY DENSITIES FOR SPACE POWER SYSTEMS. ONE CRITICAL COMPONENT TO ACHIEVE IMPROVED PERFORMANCE IS CAPACITOR STORES. THESE ARE DEPENDENT UPON ADVANCES IN LOW LOSS, HIGH ENERGY/HIGH POWER DENSITY STORAGE MATERIALS. A UNIQUE INORGANIC COMPOSITE IS PROPOSED FOR INVESTIGATION AS A HIGH ENERGY DENSITY STORAGE MATERIAL. AN APPROACH IS FORMULATED BASED ON SOL-G ...

Glass is an attractive material for microelectronic packaging because it is hermetically sealing, has a low coefficient of thermal expansion, and is compatible with d.c. circuits. Unfortunately, the working temperature of glass is too high for this application. Low-temperature processing of a sol-gel derived, aluminosilicate material for hermetic seals is proposed for electronic packaging. This ...

The quality and durability of coatings produced by virtually all thermal spray techniques could be improved by, among other things, increasing the velocity with which coatings particles impact the coated surface and by better control of the chemical and thermal environment seen by the particles during flight. A new and innovative approach to thermal spraying is proposed that can increase coating p ...

The proposed effort will apply advanced methods of hybrid learning to problems of detection and identification of sensory events (e.g., boost phase evens). Our approach aims at building a vision system capable of hybrid learning, in which symbolic (rule-based) and subsymbolic (neural network) strategies are integrated to achieve high efficiency and accuracy both in learning human comprehensible se ...

Optomec Design Company proposes to use Laser Engineered Net Shaping (LENSTM), a Rapid Prototyping and Manufacturing (RP&M) technology currently under development at Sandia National Laboratories (SNL), as a new method for integrating instrumentation (e.g., embedded sensors) into metal structural components. SNL has demonstrated the ability of the LENSTM technology to produce near net shape stainles ...

Silicon carbide materials will revolutionize semiconductor devices for military and commercial markets. The material's wide bandgap, high electric field breakdown, high thermal conductivity give SiC capabilities that far exceed those of silicon or gallium arsenide. Despite significant progress in silicon carbide development, fundamental defects--most prominently micropipes--persist. If SiC is to s ...

The properties of single-crystal silicon carbide are such that electronics devices from this material have demonstrated remarkable performance characteristics. Despite the material's promise, the material has not yet found acceptance in mainstream device markets because of the material's high cost, among other reasons. This Phase I SBIR proposes an SiC source powder with unique properties which wi ...

A novel technological approach was recently devised by Sumi Tech engineers to fabricate multilayer electronic components, which enables the manufacture of devices with very high volumetric efficiency and reliability. Inexpensive electrode materials such as copper, or aluminum are potential candidates, since the process takes place at relatively low ambient temperature (e.g., less than 400 C), thus ...
