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 ...

Microwave Technologies Incorporated proposes the prototype development of a compact cold-cathode electron buncher (CCEB) which is well-suited for applications such as sensor systems for ballistic missile defense. The CCEB will provide high-frequencyelectron bunches by combining the features of novel microscopic vacuum triodes with the he robust and reliable solid-state technology. It should prov ...

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 ...

This Phase II project is proposed to further develop and commercialize MicroCoating Technologies' NanoMiser technology for the production of high quality nanopowders. Phase I has demonstrated a novel, low-cost method able to produce a variety ofnanopowders of tailored size and composition. The results from Phase I have established a solid ground for this Phase II plan, which will focus on produc ...

A SELF-REGENERATIVE FEEDBACK TECHNIQUE IS BEING INVESTIGATEDTO SUPPRESS THE FORMATION OF SIDEBANDS THAT LIMIT THE SPECTRAL BRIGHTNESS AND GENERAL PERFORMANCE OF PRESENT HIGH-POWER FREE ELECTRON LASERS (FELS). THIS TECHNIQUE DOES NOT INVOLVE INTRA-CAVITY COMPONENTS THAT SUFFER LOSS DAMAGE DUE TO HIGH POWER OPERATION. A POTENTIAL BREAKTHROUGH IN FEL TECHNOLOGY, ANALYSIS AND SIMULATION ARE BEING PERF ...

The Navy and other defense agencies have the need for high quality deposited materials with uniques and novel microstructures that exhibit pyrophoric activity. UTRON, Inc. proposes a new and innovative approach to producing coating structures utilizingPulsed Plasma Spary Forming Technology. This is based on a repetitively pulsed plasma jey generated by a capillary arc duscharge. the pulsed plasm ...

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 ...

THE APPLICATION OF HIGH TEMPERATURE SUPERCONDUCTORS IS SEVERELY LIMITED BY THE LOW CURRENT DENSITIES ACHIEVABLE IN BULK MATERIALS, SUCH AS Y1BA2CU3O(7-X), OR 123 FOR SHORT. THE LARGE CURRENT DENSITIES OBSERVED WITHIN INDIVIDUAL GRAINS (AND IN THIN FILMS) ARE REDUCED BY "WEAK LINKS" AT THE GRAIN BOUNDARIES, CAUSED BY MISALIGNMENT OF THE ANISOTROPIC GRAINS AND BY INSULATING IMPURITY PHASES. SOME OF ...
