A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

The Directed Energy Tactical Mission Application Code (DETMAC) is a mission planning simulation tool to model directed-energy weapon capabilities, target vulnerabilities, and environmental constraints. It will be used by mission planners to visualize an entire mission timeline and prompt development of optimal tactics, techniques and procedures for successful employment of new weapon capabilities ...

This project will (i) extend and harden the PSL Editor and the Ontology-Driven XSLT Generator (ODXG) tools and (ii) extend the process description syntax (PDS) derived from the PSL for both KIF and XML/RDF formats. In addition, we will extend the PSL metatheoretical framework to support the PDS and the PSL tools by providing PSL extensions to support calendars and activity specialization, and by d ...

Modern supercontinuum (SC) light sources are generated by non-linear interactions between ultrashort laser pulses and optical fibers. These light sources have high brightness and are spatially coherent. Output in near-ultraviolet to near-infrared wavelength ranges has been demonstrated. SC wavelength ranges are constrained by the transmission and dispersion properties of the fibers. Previously, ou ...

THE RESEARCH PROGRAM WILL DEVELOP A MICROCOMPUTER BASED SYSTEM OF HARDWARE AND SOFTWARE WHICH WILL ALLOW THE USER TOEXECUTE MAINFRAME BASED CODES ON THE MICROCOMPUTER. IN ADDITION PARALLEL EXECUTION OF SEVERAL CODES AT ONCE IS POSSIBLEA SPECIAL INPUT AND OUTPUT PROCESSOR MODULES WILL ALSO BE DEVELOPED TO DEMONSTRATE THE USER FRIENDLY CAPABILITIES OF THE SYSTEM AND FACILITATE INPUT PREPARATION AND ...

Southwest Sciences¿ Phase 2 SBIR project will lead to development of residential fire sensing systems based on recently developed, low cost temperature and optical imaging sensors combined with newly introduced highly miniaturized, micropower CO sensors. Sensor modules will be part of a low power wireless network. Each module will be about ½ the size of a business card, a few mm thick, and w ...

A low-cost superconducting transition edge sensor (TES) microcalorimeter spectrometer is described for high energy and high spatial resolution X-ray energy dispersive spectroscopy and microanalysis. The proposed microcalorimeter instrument offers an energy resolution that is comparable to and potentially even better than wavelength dispersive spectrometers, thereby enabling the resolution of inter ...

A key factor of international efforts to identify and suppress the supply of and demand for nuclear materials, and thereby to deter potential traffickers, is the ability to accurately identify contradicted material and ultimately to trace it back to its origin. Alpha particle spectroscopy is widely used in nuclear forensics to assay trace quantities of sensitive nuclear materials, but the limited ...

THE DIFFICULTY IN PREDICTING STRUCTURAL DEGRADATION RATES FOR NUCLEAR POWER PLANT COMPONENTS DUE TO CORROSION AND OTHER FACTORS HAS LED TO THE NEED FOR COSTLY, TIME CONSUMING INSPECTIONS AND INCREASED COST FROM INTENTIONALLY OVERDESIGNED COMPONENTS. THE SITUATION INDICATES A SERIOUS, UNMET NEED FOR A SIMPLE BUT ACCURATE SYSTEM FOR REAL- TIME, IN SITU, NONDESTRUCTIVE ANALYSIS OF NUCLEAR POWER PLANT ...
