An indirect sensing technique for diesel fuel quantity control. Technical progress report, October 1--December 31, 1998 (open access)

An indirect sensing technique for diesel fuel quantity control. Technical progress report, October 1--December 31, 1998

Work has proceeded intensely with the objective of completing the commercial prototype system prior to the end of the contract period. At the time of this report, testing and refinement of the commercial version of the system has not been completed. During this reporting period, several major milestones were reached and many significant lessons were learned. These are described. The experimental retrofit system has achieved all performance objectives in engine dynamometer tests. The prototype commercial version of the system will begin demonstration service on the first of several Santa Maria Area Transit (SMAT) transit buses on February 1, 1999. The commercial system has been redesignated the Electronic Diesel Smoke Reduction System (EDSRS) replacing the original internal pseudonym ADSC. The focus has been narrowed to a retrofit product suitable for installation on existing mechanically-governed diesel engines. Included in this potential market are almost all diesel-powered passenger cars and light trucks manufactured prior to the introduction of the most recent clean diesel engines equipped with particulate traps and electronic controls. Also included are heavy-duty trucks, transit vehicles, school buses, and agricultural equipment. This system is intended to prevent existing diesel engines from overfueling to the point of visible particulate emissions (smoke), while …

Investigation of steady-state and transient defect populations in KH2PO4 subsequent to high fluence laser irradiation (open access)

Investigation of steady-state and transient defect populations in KH2PO4 subsequent to high fluence laser irradiation

Microscopic fluorescence imaging and time-resolved Raman scattering are employed to investigate the effect of high power 355 nm laser irradiation on preexisting and transient defect populations in KH 2 PO 4 . Defect clusters in the bulk of KDP crystals are imaged with 1 micron spatial resolution using their NIR emission. The intensity of the emission clusters varies widely within the image field. The exposure of the crystal at high power 355 nm, 3 ns laser irradiation leads to a reduction of the number of observed optically active centers. In addition, time resolved Raman scattering was employed to study the transient generation of defects during high power 355 nm laser irradiation.

Ion and Neutral Species in C(2)F(6) and CHF(3) Dielectric Etch Discharges (open access)

Ion and Neutral Species in C(2)F(6) and CHF(3) Dielectric Etch Discharges

Relative concentrations of reactive ions, neutral radicals, resist and substrate etch products have been measured in dielectric etch chemistries using an uncollided beam mass spectrometer / ion extractor from Hiden Analytical. Analysis techniques employed include both electron impact ionization and dissociative ionization of neutral gas, and potential bias extraction of positive ions from the reactor discharge volume. Measurements were made in C{sub 2}F{sub 6} and CHF{sub 3} discharges in an inductively coupled plasma (ICP-GEC) research reactor operating with power densities, pressures, gas compositions and wafer materials typical of those found in etch processing tools. Wafer substrates investigated included blanket silicon wafers and silicon wafers with varying amounts of photo-resist coverage of the surface (20%, 80% and 100%). In C{sub 2}F{sub 6} discharges CF{sub 3}{sup +} was consistently the dominant fluorocarbon ion present, in agreement with published cross sections for dissociative ionization [ 1,2.3,4.5,6]. Smaller concentrations of CF+, CF{sub 2}{sup -}, and C{sub 2}F{sub 5}{sup +}, were also observed, though the dissociative ionization production of C{sub 2}F{sub 5}{sup +} was a factor of five smaller than would be expected from published cross section values. The presence of photo-resist, even in small amounts, was found to produce marked changes in the discharge …

Joint Combined Exchange Training (JCET) and Human Rights: Background and Issues for Congress (open access)

Joint Combined Exchange Training (JCET) and Human Rights: Background and Issues for Congress

The National Defense Authorization Act for Fiscal Years 1992 and 1993 allows U.S. special operations forces (SOF) to train under the Joint Combined Exchange Training (JCET) program in foreign countries, and does not prohibit training in nations where human rights violations have been reported. Such training includes instructing host government military units in lethal and nonlethal skills. Controversy has erupted over JCET missions in countries whose militaries are suspected or known to have committed human rights abuses. This report describes relevant legislation, SOF, JCET, alleged human rights abuses, and recent congressional initiatives and discusses further options and issues.

Plutonium Immobilization Canister Loading (open access)

Plutonium Immobilization Canister Loading

This disposition of excess plutonium is determined by the Surplus Plutonium Disposition Environmental Impact Statement (SPD-EIS) being prepared by the Department of Energy. The disposition method (Known as ''can in canister'') combines cans of immobilized plutonium-ceramic disks (pucks) with vitrified high-level waste produced at the SRS Defense Waste Processing Facility (DWPF). This is intended to deter proliferation by making the plutonium unattractive for recovery or theft. The envisioned process remotely installs cans containing plutonium-ceramic pucks into storage magazines. Magazines are then remotely loaded into the DWPF canister through the canister neck with a robotic arm and locked into a storage rack inside the canister, which holds seven magazines. Finally, the canister is processed through DWPF and filled with high-level waste glass, thereby surrounding the product cans. This paper covers magazine and rack development and canister loading concepts.

Solid Phase Microextraction and Miniature Time-of-Flight Mass Spectrometer (open access)

Solid Phase Microextraction and Miniature Time-of-Flight Mass Spectrometer

A miniature mass spectrometer, based on the time-of-flight principle, has been developed for the detection of chemical warfare agent precursor molecules. The instrument, with minor modifications, could fulfill many of the needs for sensing organic molecules in various Defense Programs, including Enhanced Surveillance. The basic footprint of the instrument is about that of a lunch box. The instrument has a mass range to about 300, has parts-per-trillion detection limits, and can return spectra in less than a second. The instrument can also detect permanent gases and is especially sensitive to hydrogen. In volume, the device could be manufactured for under $5000.

Subsurface imaging using the spectral polarization difference technique and NIR illumination (open access)

Subsurface imaging using the spectral polarization difference technique and NIR illumination

A subsurface imaging system is utilized to test the ability of the spectral polarization difference imaging technique for deep subsurface imaging in tissues. The illumination of the system is derived from compact class III lasers in the red and NIR spectral region and, alternatively, from a white light source and selection of the appropriate illumination wavelength using band-pass optical filters. The experimental results demonstrate detection and imaging of a high-scattering object located up to 1.5 cm underneath the surface of a host chicken tissue.

Vision System for Remote Strain/Deformation Measurement (open access)

Vision System for Remote Strain/Deformation Measurement

Machine vision metrology is ideally suited to the task of non-contact/non-intrusive deformation and strain measurement in a remote system. The objective of this work-in-progress is to develop a compact instrument for strain measurement consisting of a camera, image capture card, PC, software, and light source. The instrument is portable and useful in a variety of applications and environments. A digital camera with a microscopic lens is connected to an image capture card in a PC. Commercially available image processing software is used to control the image capture and image processing steps leading up to displacement/strain measurement. Image processing steps include filtering and edge/feature enhancement. Custom software is required to control/automate certain elements of the acquisition and processing. Images of a region on the surface of a specimen are acquired at hold points (during static tests) or at regular time intervals (during transients). Salient features in the image scene (microstructure, oxide deposits, etc.) are observed in subsequent images. The strain measurement algorithm characterizes relative motion of the salient features with individual displacement vectors yielding 2-D deformation equations. The set of deformation equations is solved simultaneously to yield unknown deformation gradient terms that are used to express 2-D strain. The overall concept, …
