Modern supercontinuum (SC) light sources are generated by non-linear interactions between ultrashort pulse lasers and optical fibers. Output in near-ultraviolet to near-infrared wavelength ranges has been demonstrated. These light sources have high brightness and are spatially coherent. Recently, output to 4.5 µm was achieved using fluoride glass fibers; optical absorption by the fiber prevents l ...

Southwest Sciences proposes development of residential fire sensing systems based on low cost optical imaging sensors combined with newly introduced highly miniaturized, low power CO sensors. Sensor modules will also include temperature sensors. The 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 will operate for ...

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 objective of the research presented in this Phase II proposal is to extend and understand the success of the Phase I work and to conduct the work plans developed in the Phase I activities. The primary objective of this research is to develop answers that will remove barriers to implementation of on-site generation technology as a replacement for chlorine gas, and to provide scientific answers ...

Optimized Network Sensing (ONS) is a Modeling and Simulation Toolset which provides the capability for rapid and cost effective evaluation of currently deployed Chemical/Biological sensor networks or design of new networks. The Phase I effort will demonstarte the feasibility of such a toolset and determine which software modules best optimize the solution. Proven modules will be integrated in a fl ...

RL Associates Inc. proposes to conduct research leading to the development of a remote Raman system for the standoff detection of peroxide-based IED`s. While there have been several Raman systems funded by the Gov`t previously for this pupose, the RL Associates Portable Remote Eyesafe Raman (PREMIR)system is eyesafe and based on our patented volume holographic grating technology to replace the nor ...

TPL proposes to demonstrate the feasibility of its EnerPak power solution for use in unattended ground sensors (UGS) for border security. The EnerPak combines energy harvesting technology with miniaturized electrochemical storage devices to provide a hybrid power source for sensors deployed in remote locations. Our solution uniquely meets the needs of border security UGS and delivers long life (at ...

THE WORK PROPOSED IN THIS EFFORT IS DIRECTED TOWARDS DETERMINING THE CORRELATION BETWEEN OBSERVED AIRBORNE RADIOIODINE CONCENTRATIONS IN THE AUXILIARY AND FUEL HANDLING BUILDINGS AT TMI-2 FOLLOWING THE ACCIDENT IN 1979 WITH DIURNAL TEMPERATURE VARIATIONS. APPROXIMATELY 5000 MEASUREMENTS WERE MADE DURING THE PERIOD APRIL-JULY, 1979 INDESIGNATED AREAS OF THE AUXILIARY/FUEL HANDLING BUILDING AND THE ...
