While many applications may have access to harvestable energy in the form of solar radiation (or other ambient light), wind, environmental vibration, or wave motion, not all do. In this proposal, RMD targets the most challenging applications, sensors that must operate for many months or years and which have undependable or no access to environmental energy. These sensors need a self contained, com ...

Current military combat operations emphasize the use of teams, who are often expected to rapidly deploy together. This rapid deployment cycle is especially true for military transition teams. Such teams must quickly become highly functioning, as characterized by high levels of team cognitive readiness. To address the need for newly formed teams to rapidly become cognitively ready and effective, th ...

Certain lanthanide halides have significantly higher light output than NaI:Tl, the comparison standard for scintillators, plus other important properties, including fast decay times and excellent proportionality. Unfortunately, lanthanide halides grown by traditional melt processes have high production costs and limited availability. Crystals are usually limited to about 5 cm x 5 cm, right cylinde ...

It is proposed to develop a novel process for growth of high quality CZT crystals for nuclear detection applications. Currently the THM process is the technology of choice for production of high quality CZT crystals. This process, however, suffers from extremely low growth rates. The development effort proposed here will seek to increase the crystal growth rate by 5-10 times the current levels ...

Three nuclides are especially useful in detecting thermalized neutrons: helium-3, lithium-6 , and boron-10. Since current demand will deplete reserves of helium-3 in roughly two years, there is a large desire to develop detectors that have the capacity to replace helium-3 tubes. In this proposal we spell out our plan to adapt Neotron''s already developed fission neutron detector into a high effic ...

A PROGRAM IS PROPOSED TO EVALUATE THE FEASIBILITY OF FORMING IMPROVED SIMOX MATERIAL BY CONTOURING THE ENERGY OF THE INCIDENT OXYGEN IONS. DURING THE IMPLANTATION PROCESS OF SIGNIFICANT AMOUNT OF SUBSTRATE MATERIAL IS REMOVED BY SPUTTERING. ALTHOUGH THE RANGE R(P) OF INCIDENT IONS REMAINS CONSTANT, TO FIRST ORDER, DURING THE IMPLANT, THE SPUTTERING AWAY OF THE SURFACE CAUSES INCIDENT IONS TO COME ...

SPIRE HAS RECENTLY DEMONSTRATED THAT SIMOX WAFERS OF SUFFICIENTLY HIGH QUALITY AND LOW DEFECT DENSITY TO SUPPORT BIPOLAR DEVICE APPLICATIONS CAN BE PRODUCED. TO ACHIEVE SUPERIOR QUALITY, HOWEVER, PRESENTLY REQUIRES PRODUCTION METHODS WHICH RESULT IN RELATIVELY HIGH COST. A RESEARCH PROGRAM IS PROPOSED WHICH WILL ESTABLISH THE FOUNDATION FOR LOWER COST, HIGHER THROUGHPUT PRODUCTION ALTERNATIVES WHI ...

A NUMBER OF NASA SATELLITES HAVE OBTAINED DATA WHICH CAN BE USED FOR DETERMINING AMBIENT ATMOSPHERIC DENSITY STRUCTURE PARAMETERS. AMONG THEM ARE THE ATMOSPHERIC EXPLORER SERIES -C, -D, AND -E) AND THE SOLAR MESOSPHERIC EXPLORER (SME). IT IS PROPOSED TO ANALYZE THESE DATA TO OBTAIN ESTIMATES OF ATMOSPHERIC DENSITY SPATIAL STRUCTURE PARAMETERS, POWER SPECTRAL DENSITIES ETC. THIS WILL PROVIDE INPUTS ...

THE PROPOSED FIBLOC SENSOR PROVIDES AN ECONOMIC MEANS TO PROTECT, LITERALLY, MILES OF A PREFERRED PERIMETER REGION AGAINST UNAUTHORIZED INTRUSIONS. THE OPTICAL FIBERS EMPLOYED INT HE FIBLOC SENSOR PROPAGATE CW OR PULSED INFRARED LIGHT SIGNALS WHOSE TRANSMISSION AND/OR REFLECTION SENSITIVITY IS AFFECTED BY MECHANICAL PRESSURE SUCH AS WOULD BE PRODUCED BY THE DISTENSION OF SURFACED MOUNTED FIBERS AL ...
