NEW TECHNOLOGIES ARE REQUIRED FOR THE DETECTION AND IMAGING OF VISIBLE LIGHT, GAMMA RAYS AND NEUTRONS IN HIGH RADIATION ENVIRONMENTS SUCH AS THOSE ENCOUNTERED IN SPACE. CURRENTLY AVAILABLE, CRYSTALLINE SILICON DETECTOR ARRAYS SUCH AS CHARGE COUPLED DEVICES (CCD) ARE EXTREMELY SUSCEPTIBLE TO RADIATION DAMAGE AND A FEW KILORADS OF HIGH ENERGY PROTONS CAN SERIOUSLY DEGRADE PERFORMANCE IN A MATTER OF ...

Rocket motors that develop greater thrust with lower weight and volume require-ments are an ever present goal of the BMDO. One method of providing this is through formulation of higher energy propellant mixtures. TPL proposes to develop a new method of effectively producing new high perfor-mance propellant constituents for launch, orbit-orbit transfer and station keeping propulsion systems. The p ...

THE PROPOSED RESEARCH ATTEMPTS TO DEVELOP AN ADVANCED CAPACITOR USING SiC FOR HIGH TEMPERATURE (400 0C), HIGH POWER, AND HIGH DENSITY ELECTRONIC COMPONENTS FOR AIRCRAFT OR AEROSPACE APPLICATION. THE CONVENTIONAL CAPACITOR CONSISTS OF A LARGE NUMBER OF METALLIZED POLYSULFONE FILM CAPACITORS IN PARALLEL ENCLOSED IN A HERMETICALLY SEALED METAL CASE. PROBLEMS WITH ELECTRICAL FAILURE THERMAL FAILURE AN ...

THE PROPOSED RESEARCH ADDRESSES THE DEVELOPMENT OF SEVERAL DIFFERENT TYPES OF REFRACTORY BRAZING FILLERS AND EVALUATION OF THEIR PROPERTIES FOR HIGH TEMPERATURE AND LOW VAPOR PRESSURE APPLICATIONS. REFRACTORY METALS AND ALLOYS ARE OMNIPRESENT IN NUCLEAR SPACE REACTOR ASSEMBLIES. JOINING AND BONDING PARTS MADE OF SUCH MATERIALS WHILE STILL MAINTAINING THEIR EFFECTIVENESS IS A MAJOR CONCERN. FABRICA ...

We propose to develop a novel and ambitious tool for large-scale development: a fourth-generation computer language (4GL) based upon an object-oriented generalization of the hierarchical block diagram paradigm, with powerful integrated simulation capabilities. Developers would assemble a prototype in a connect-the-blocks visual programming environment, test and evaluate it via simulation, then ite ...

We propose a systematic investigation of crystalline Si structures as their dimensions are reduced to quantum sizes (5-10 nm). For convenience, we have chosen Si on insulator (SOI) material for optical and electrical characterization. Our nanofabrication approach relies on simple laser interferometric lithography techniques that are uniquely adaptable to large area manufacturing. Suitable applic ...
