The 2010 Decennial Census: Background and Issues

Description: The U.S. Constitution--Article 1, Section 2, clause 3, as modified by Section 2 of the Fourteenth Amendment--requires a population census every 10 years, to serve as the basis for reapportioning seats in the House of Representatives. Decennial census data also are used for within-state redistricting and in certain formulas that determine the annual distribution of more than $400 billion dollars in federal and state funds. This report discusses the major innovations that were planned for the 201… more

29th Annual PolyMAC Meeting: Book of Abstracts

Description: A sixteen-run, Resolution IV, fractional factorial screening design has been used to evaluate the relative significance of seven independent material and process variables for an electrically deposited commercial acrylic paint. A Resolution IV design was chosen so that variable interactions could be detected without any interference from the effects of the variables themselves. Because resource limitations did not permit use of a Resolution V design, the two-way interactions were confounded wit… more

2D Spatial Frequency Considerations in Comparing 1D Power Spectral Density Measurements

Description: The frequency footprint of ID and 2D profiling instruments needs to be carefully considered in comparing ID surface roughness spectrum measurements made by different instruments. Contributions from orthogonal direction frequency components can not be neglected. The use of optical profiling instruments is ubiquitous in the measurement of the roughness of optical surfaces. Their ease-of-use and non-contact measurement method found widespread use in the optics industry for measuring the quality of… more

A 3d Parallel Beam Dynamics Code for Modeling High BrightnessBeams in Photoinjectors

Description: In this paper we report on IMPACT-T, a 3D beam dynamics code for modeling high brightness beams in photoinjectors and rf linacs. IMPACT-T is one of the few codes used in the photoinjector community that has a parallel implementation, making it very useful for high statistics simulations of beam halos and beam diagnostics. It has a comprehensive set of beamline elements, and furthermore allows arbitrary overlap of their fields. It is unique in its use of space-charge solvers based on an integrat… more

Absolute Measurement of the Polarization of High Energy Proton Beams at RHIC

Description: The spin physics program at the Relativistic Heavy Ion Collider (RHIC) requires knowledge of the beam polarization to better than 5%. Such a goal is made the more difficult by the lack of knowledge of the analyzing power of high energy nuclear physics processes. To overcome this, a polarized hydrogen jet target was constructed and installed at one intersection region in RHIC where it intersects both beams and utilizes the precise knowledge of the jet atomic hydrogen beam polarization to measure… more

Accident source terms for light-water nuclear power plants using high-burnup or MOX fuel.

Description: Representative accident source terms patterned after the NUREG-1465 Source Term have been developed for high burnup fuel in BWRs and PWRs and for MOX fuel in a PWR with an ice-condenser containment. These source terms have been derived using nonparametric order statistics to develop distributions for the timing of radionuclide release during four accident phases and for release fractions of nine chemical classes of radionuclides as calculated with the MELCOR 1.8.5 accident analysis computer cod… more

Accident source terms for pressurized water reactors with high-burnup cores calculated using MELCOR 1.8.5.

Description: In this study, risk-significant pressurized-water reactor severe accident sequences are examined using MELCOR 1.8.5 to explore the range of fission product releases to the reactor containment building. Advances in the understanding of fission product release and transport behavior and severe accident progression are used to render best estimate analyses of selected accident sequences. Particular emphasis is placed on estimating the effects of high fuel burnup in contrast with low burnup on fiss… more

Accurate determination of impurity concentrations in plutonium metals by statistical evaluation of analytical data

Description: Analytical data from a plutonium-metal exchange program conducted by six ERDA laboratories are statistically evaluated. The objective is an accurate determination of five metal impurities (aluminum, chromium, iron, nickel, silicon) in each of three plutonium metals by using data from four analytical methods. The statistical evaluation yields the weighted mean and its standard deviation for each method, plutonium metal, and impurity, using a procedure that minimizes the effect of outliers by ass… more

Actinic defect counting statistics over 1 cm2 area of EUVL mask blank

Description: As a continuation of comparison experiments between EUV inspection and visible inspection of defects on EUVL mask blanks, we report on the result of an experiment where the EUV defect inspection tool is used to perform at-wavelength defect counting over 1 cm{sup 2} of EUVL mask blank. Initial EUV inspection found five defects over the scanned area and the subsequent optical scattering inspection was able to detect all of the five defects. Therefore, if there are any defects that are only detect… more

Actinic Mask Inspection at the ALS Initial Design Review

Description: This report is the first milestone report for the actinic mask blank inspection project conducted at the VNL, which forms sub-section 3 of the Q1 2003 mask blank technology transfer program at the VNL. Specifically this report addresses deliverable 3.1.1--design review and preliminary tool design. The goal of this project is to design an actinic mask inspection tool capable of operating in two modes: high-speed scanning for the detection of multilayer defects (inspection mode), and a high-resol… more

Adaptive Importance Sampling Monte Carlo Simulation of Rare Transition Events

Description: We present an adaptive importance sampling method for quantifying the statistics of rare-event processes in atomistic simulations. The approach is based on an explicit evaluation of the probability that a sequence of states (or path) initiating in a state A leads to a reactive transition event to final state B. The importance sampling method seeks to bias the sampling of system trajectories such that those that contribute significantly, i.e. those that characterize reactive transitions, are gen… more
