Development of a Whole-Wafer, Macroscale Inspection Software Method for Semiconductor Wafer Analysis

This report describes the non CRADA-protected results of the project performed between Nova Measuring Systems, Ltd., and the Oak Ridge National Laboratory to test and prototype defect signature analysis method for potential incorporation into an in-situ wafer inspection microscope. ORNL's role in this activity was to collaborate with Nova on the analysis and software side of the effort, wile Nova's role was to build the physical microscope and provide data to ORNL for test and evaluation. The objective of this project was to adapt and integrate ORNL's SSA and ADC methods and technologies in the Nova imaging environment. ORNL accomplished this objective by modifying the existing SSA technology for use as a wide-area signature analyzer/classifier on the Nova macro inspection tool (whole-wafer analysis). During this effort ORNL also developed a strategy and methodology for integrating and presenting the results of SSA/ADC analysis to the tool operator and/or data management system (DMS) used by the semiconductor manufacturer (i.e., the end-user).

Real-Time Risk and Fault Management in the Mission Evaluation Room of the International Space Station (open access)

Real-Time Risk and Fault Management in the Mission Evaluation Room of the International Space Station

Effective anomaly resolution in the Mission Evaluation Room (MER) of the International Space Station (ISS) requires consideration of risk in the process of identifying faults and developing corrective actions. Risk models such as fault trees from the ISS Probablistic Risk Assessment (PRA) can be used to support anomaly resolution, but the functionality required goes significantly beyond what the PRA could provide. Methods and tools are needed that can systematically guide the identification of root causes for on-orbit anomalies, and to develop effective corrective actions that address the event and its consequences without undue risk to the crew or the mission. In addition, an overall information management framework is needed so that risk can be systematically incorporated in the process, and effectively communicated across all the disciplines and levels of management within the space station program. The commercial nuclear power industry developed such a decision making framework, known as the critical safety function approach, to guide emergency response following the accident at Three Mile Island in 1979. This report identifies new methods, tools, and decision processes that can be used to enhance anomaly resolution in the ISS Mission Evaluation Room. Current anomaly resolution processes were reviewed to identify requirements for effective …

New neutron cross section and fission yield data for SNManalysis (open access)

New neutron cross section and fission yield data for SNManalysis

Neutron cross-section data are fundamental for the design ofnuclear interrogation systems, the maintenance of nuclear materials andwaste, and the understanding the consequences of nuclear catastrophe.Although a large body of nuclear data exists, it is often old,unreliable, or poorly determined. For several years we have collaborated,as part of an IAEA Coordinated Research Project, to precisely measure thepartial thermal neutron gamma ray cross sections for all elements fromhydrogen to uranium at the Budapest Reactor. These data will replace theunreliable tables of Lone et al [1], still widely in use, and will bepublished as an IAEA TECDOC.

Microwave Treatment as a Pesticide Alternative for Stored-Products (open access)

Microwave Treatment as a Pesticide Alternative for Stored-Products

This CRADA was a continuation of earlier work with Micro-Grain, Inc. to develop power, high frequency microwave treatment process to treat insect infested grain. ORNLs role was as a subcontractor to Micro-Grain's Phase II SBIR project funded by the US Department of Agriculture. The primary objective was to develop a commercial scale prototype unit capable of treating infested grain at flow rates approaching 1 kg/sec, which is required to be viable in the grain handling industry. A flow rate of {approx} 0.12 Kg/second was demonstrated at 20 kW microwave power level with 100% kill rate. The system is capable of 200 kW however waveguide arcing due to grain dust in the waveguide limited the power to 20 kW during the tests. Development tasks performed during the project included modification of an existing high-power microwave exposure facility to uniformly process large grain samples at high flow rates and improved instrumentation to detect grain flow and uniformity. Microwave processing tasks include a series of controlled exposure tests using infested grain samples provided and analyzed by the University of Oklahoma. Grain samples were infested with red flour beetles which proved the most difficult to kill in earlier tests. Most of the samples processed …

On-Line Measurement of Beryllium, Chromium, and Mercury by Using Aerosol Beam Focused Laser-Induced Plasma Spectrometer and TIme-Integrated Filter Sampling and Reference Method (open access)

On-Line Measurement of Beryllium, Chromium, and Mercury by Using Aerosol Beam Focused Laser-Induced Plasma Spectrometer and TIme-Integrated Filter Sampling and Reference Method

A novel real-time monitor for aerosol particles has been developed by the Oak Ridge National Laboratory (ORNL). The instrument is designed to perform in-situ measurement for the elemental composition of aerosol particles in flue gas. They had tested this monitor at the Eastman Chemical Company in July 2001 taking advantage of the emissions from a waste incinerator operated by the company as the background. To investigate the behavior and response of the monitor under simulated/known conditions, stock solutions of prepared metal concentration(s) were nebulized to provide spikes for the instrument testing. Strengths of the solutions were designed such that a reference method (RM) was able to collect sufficient material on filter samples that were analyzed in a laboratory to produce 30-minute average data points. Parallel aerosol measurements were performed by using the ORNL instrument. Recorded signal of an individual element was processed and the concentration calculated from a calibration curve established prior to the campaign. RM data were able to reflect the loads simulated in the spiked waste stream. However, it missed one beryllium sample. The possibility of bias exists in the RM determination of chromium that could lead to erroneous comparison between the RM and the real-time monitoring data. …

Quantitative Assessment of Distributed Energy Resource Benefits (open access)

Quantitative Assessment of Distributed Energy Resource Benefits

Distributed energy resources (DER) offer many benefits, some of which are readily quantified. Other benefits, however, are less easily quantifiable because they may require site-specific information about the DER project or analysis of the electrical system to which the DER is connected. The purpose of this study is to provide analytical insight into several of the more difficult calculations, using the PJM power pool as an example. This power pool contains most of Pennsylvania, New Jersey, Maryland, and Delaware. The techniques used here could be applied elsewhere, and the insights from this work may encourage various stakeholders to more actively pursue DER markets or to reduce obstacles that prevent the full realization of its benefits. This report describes methodologies used to quantify each of the benefits listed in Table ES-1. These methodologies include bulk power pool analyses, regional and national marginal cost evaluations, as well as a more traditional cost-benefit approach for DER owners. The methodologies cannot however determine which stakeholder will receive the benefits; that must be determined by regulators and legislators, and can vary from one location to another.

NSLS 2002 ACTIVITY REPORT (NATIONAL SYNCHROTRON LIGHT SOURCE ACTIVITY REPORT 2002).

The year 2002 has been another highly productive year at the NSLS and an impressive array of highlights from this scientific activity is included in this Activity Report. They have taken significant steps this past year toward better supporting beamlines and users. The number of user science support staff has been increased by about ten positions. They have also worked with their users, DOE, and the other DOE synchrotron facilities to develop a new, more flexible user access policy. Doing things safely remains a top priority, and they are reviewing their training and safety requirements to ensure they are thorough and everyone fully understands the necessity of abiding by them. A major development this past year was approval from DOE for BNL to begin the conceptual design of the Center for Functional Nanomaterials (CFN). The CFN will have a dramatic impact on nanoscience in the Northeast, facilitating the synthesis, characterization and scientific exploration of new classes of novel nanostructured materials. It will be located adjacent to the NSLS and a number of NSLS beamlines will be optimized to serve the needs of the nanoscience community. The NSLS and CFN user programs will be coordinated to facilitate easy access to both …

Development of a Rolling Process Design Tool for Use in Improving Hot Roll Slab Recovery (open access)

Development of a Rolling Process Design Tool for Use in Improving Hot Roll Slab Recovery

In this quarter, our primary effort has been focused on model verification, emphasizing on consistency in result for parallel and serial simulation runs, Progress has been made in refining the parallel thermal algorithms and in diminishing discretization effects in the contact region between the rollers and slab. We have received the metrology data of the ingot profile at the end of the fifth pass from Alcoa. Detailed comparisons between the data and the initial simulation result are being performed. Forthcoming from Alcoa are modifications to the fracture model based on additional experiments at lower strain rates. The original fracture model, was implemented in the finite element code, but damage in the rolling simulation was not correct due to the modeling errors at lower strain rates and high stress triaxiality. Validation simulations for the fracture model will continue when the experimentally-based adjustments to the parameter values become available.

Performance Technolgies for Peta-Scale Systems: A White Paper Prepared by the Performance Evaluation Research Center (open access)

Performance Technolgies for Peta-Scale Systems: A White Paper Prepared by the Performance Evaluation Research Center

Future-looking high end computing initiatives will deploy powerful, large-scale computing platforms that leverage novel component technologies for superior node performance in advanced system architectures with tens or even hundreds of thousands of nodes. Recent advances in performance tools and modeling methodologies suggest that it is feasible to acquire such systems intelligently and achieve excellent performance, while also significantly reducing the user time required to attain high performance. These developments are relevant to several aspects of future HEC technology outlined in the recent HECRTF white paper request, in particular items 5.4, 5.5, 5.6, and 5.8. We envision the following specific capabilities: (1) Performance modeling tools, available to researchers and vendors, will extrapolate performance from prototype systems to full-scale systems, and even accurately predict performance behavior before systems are manufactured, thus enabling both improved designs and more intelligent selection of systems in procurements. (2) System simulation facilities, implemented on highly parallel platforms and available to researchers and vendors, will for instance realistically model the performance of a specific interprocessor network design running a specific scientific application code. As with item 1, these facilities can lead both to improved designs and procurement decisions that yield significantly greater sustained performance for targeted scientific applications. …

Investigation of the Electronic Structure of Solid Density Plasmas by X-Ray Scattering

We present an improved analytical expression for the x-ray dynamic structure factor from a dense plasma which includes the effects of weakly bound electrons. This result can be applied to describe scattering from low to moderate Z plasmas, and it covers the entire range of plasma conditions that can be found in inertial confinement fusion experiments, from ideal to degenerate up to moderately coupled systems. We use our theory to interpret x-ray scattering experiments from solid density carbon plasma and to extract accurate measurements of electron temperature, electron density and charge state. We use our experimental results to validate various equation-of-state models for carbon plasmas.

Analysis of Shock-Void Experiment (open access)

Analysis of Shock-Void Experiment

The authors compare CALE simulations with recent experimental results of a laser-induced shock traversing a spherical under-dense region (''void''). In this report the experimental results are described, as well as several numerical attempts at explaining the observed radiographs. The conclusion is that the numerical simulations at this time cannot satisfactorily explain the experiment. The simulations also indicate that the introduction of air gaps between the under-dense sphere and the surrounding foam can greatly change the behavior of the shocked sphere. Thus fabrication details may play an important role in the detailed evolution of this experiment. Regardless of the simulations, analysis of the observed time sequence indicates that reproducibility of this experiment may be a factor. To settle this issue, further experiments of this kind will be required.

Integration of Xantrex HY-100 Hybrid Inverter with an AC Induction Wind Turbine (open access)

Integration of Xantrex HY-100 Hybrid Inverter with an AC Induction Wind Turbine

Several issues must be addressed before solid-state inverters can be used in wind-diesel systems with larger wind turbines. This project addresses those issues by using a commercial hybrid inverter designed for PV-diesel systems and modifying the inverter for use with an AC induction wind turbine. Another approach would have entailed building an inverter specifically for use with an AC induction wind turbine, but that was beyond the scope of this project. The inverter chosen for this project was a Xantrex HY-100, an inverter designed for PV systems. The unit consists of an inverter/rectifier bridge, a generator interface contactor, a battery charge controller, a hybrid controller, and the associated control electronics. Details of the inverter may be found in Appendix A. A twofold approach was taken to integrating the existing inverter for use with an AC induction wind turbine: 1) development of a detailed model to model both steady-state and transient behavior of the system, and 2) modification and testing of the inverter with an induction wind turbine based on the modeling results. This report describes these two tasks.

Model for TCLP Releases from Waste Glasses (open access)

Model for TCLP Releases from Waste Glasses

A first-order property model for normalized Toxicity Characteristic Leaching Procedure (TCLP) release as a function of glass composition was developed using data collected from various studies. The normalized boron release is used to estimate the release of toxic elements based on the observation that the boron release represents the conservative release for those constituents of interest. The current TCLP model has two targeted application areas: (1) delisting of waste-glass product as radioactive (not mixed) waste and (2) designating the glass wastes generated from waste-glass research activities as hazardous or non-hazardous. This report describes the data collection and model development for TCLP releases and discusses the issues related to the application of the model.

This report describes the results of SuperLig{Reg} 639 column tests conducted at the Savannah River Technology Center (SRTC) in support of the Hanford River Protection Project - Waste Treatment Plant (RPP-WTP). The RPP-WTP contract was awarded to Bechtel National Inc. (BNI) for the design, construction, and initial operation of a plant for the treatment and vitrification of millions of gallons of radioactive waste currently stored in tanks at Hanford, WA. Part of the current treatment process involves the removal of technetium from tank supernate solutions using columns containing SuperLig{Reg} 639 resin. This report is part of a body of work intended to quantify and optimize the operation of the technetium removal columns with regard to various parameters (such as liquid flow rate, column aspect ratio, resin particle size, loading and elution temperature, etc.). The tests were conducted using nonradioactive simulants of the actual tank waste samples containing rhenium as a surrogate for the technetium in the actual waste. A previous report focused on the impacts of liquid flow rate and column aspect ratio upon performance.
