We propose a 6 month program during which we will develop and demonstrate an approach for generating well-characterized atomic and molecular beams of metastable species. Such beam sources are necessary for the microelectronics and plasma processing industries because they would provide a valuable tool required to establish a solid database of plasma-related collision processes. This improved and e ...

We propose to characterize the early stage of consolidation of non-spherical powders to further the development of process models to enable simulation of powder metallurgy manufacturing for the consumer market, especially the automotive industry. Typically, spherical powders with a narrow size distribution are used for aerospace applications, while low-cost powders with irregular shapes and a wide ...

Arca proposes research leading to development of a suite of methodology support products to help meet the need for innovative assurance techniques appropriate for emerging information technologies. The product will consist of a licensable methodology and supporting materials for specifying, building, and evaluating assurance arguments for products and systems based on the capability of security en ...

OPTRA is proposing the development of an all-reflecting stationary Fourier transform spectrometer, based on the use of Fresnel mirrors and a linear uncooled amorphous silicon microbolometer array to produce spectra in the 1 to 5 micron region with resolution of 5nm. Concentration, temperature and soot volume fraction will be derived from the measured emission spectra of a flame. An amorphous silic ...

A fire fighter's ability to effectively combat fire is strongly dependant on the degree to which his clothing limits exposure to heat and flame. Available heat- and flame-retardant garments significantly increase exposure, but use environmentally hazardous additives; additionally, further enhancements in flame-retardation are deisred. Recent research at Oak Ridge National Laboratory and elsewher ...

The proposed program will investigate fabrication of low-cost and stable Si- based filterless solar-blind UV detectors on radiation-hard silicon-on-insulator (SOI) structures. By fabricating detectors on silicon thin films, the active device layer thickness can be chosen so that shortwave photons are detected within the active layer, while the longer wavelengths are absorbed in a substrate which i ...

THE OBJECTIVE OF THE PHASE I RESEARCH IS TO DETERMINE THE TECHNICAL FEASIBILITY OF THE DEVELOPMENT OF A LONG RANGE RADIOACTIVE PLUME TRANSPORT MODEL/CODE FOR THE NRC. THIS CODE WOULD BE USED TO SIMULATE THE MOVEMENT, DISPERSION, DECAY, AND DEPOSITION OF RADIONUCLIDES RELEASED FROM SEVERE NUCLEAR REACTOR ACCIDENTS, SUCH AS THE CHERNOBYL ACCIDENT. IT IS DESIRED THAT ALL RELEVANT PHYSICAL AND CHEMICA ...

The development of a Fourier transform spectrometer with a minimum number of moving parts (or more ideally no moving parts - the so-called stationary spectrometer) has been the subject of considerable research and development. Recent work on a birefringence based system has resulted in the introduction of a commercial version of the system. While a significant step toward the goal of a practical ...
