Border Security: More Emphasis on State's Consular Safeguards Could Mitigate Visa Malfeasance Risks

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Issuing a U.S. visa to a foreign citizen in exchange for money or something of value is a crime that can facilitate entry into the United States of unqualified persons, including those who may wish to do our country harm. Internal controls make it difficult for an employee to commit visa malfeasance without being detected, but, despite these safeguards, visa malfeasance does occur. GAO examined (1) Stat… more

DOD's High-Risk Areas: High-Level Commitment and Oversight Needed for DOD Supply Chain Plan to Succeed

Description: Testimony issued by the Government Accountability Office with an abstract that begins "Since 1990 the Department of Defense's (DOD) supply chain management processes have been on GAO's list of high-risk areas needing urgent attention and fundamental transformation to ensure that they function in the most economical, efficient, and effective manner possible. Recently in collaboration with the Office of Management and Budget (OMB), DOD developed a plan to address some of the systemic weaknesses a… more

Defense Trade: Implementation of Exon-Florio

Description: Testimony issued by the Government Accountability Office with an abstract that begins "The 1988 Exon-Florio amendment to the Defense Production Act authorizes the President to suspend or prohibit foreign acquisitions of U.S. companies that may harm national security, an action the President has taken only once. Implementing Exon-Florio can pose a significant challenge because of the need to weigh security concerns against U.S. open investment policy--which requires equal treatment of foreign an… more

The Vetter-Sturtevant Shock Tube Problem in KULL

Description: The goal of the EZturb mix model in KULL is to predict the turbulent mixing process as it evolves from Rayleigh-Taylor, Richtmyer-Meshkov, or Kelvin-Helmholtz instabilities. In this report we focus on an example of the Richtmyer-Meshkov instability (which occurs when a shock hits an interface between fluids of different densities) with the additional complication of reshock. The experiment by Vetter & Sturtevant (VS) [1], involving a Mach 1.50 incident shock striking an air/SF{sub 6} interface,… more

Ignition Target Fabrication and Fielding for the National Ignition Facility

Description: Continued advances in the design of ignition targets have stimulating new development paths for target fabrication, with potentially important simplifications for fielding cryogenic ignition targets for the National Ignition Facility. Including graded dopants in ablators as well as optimizing capsule and fuel layer dimensions increase implosion stability. This has led to developments of micron-scale fill tubes to fill and field the targets. Rapid progress has been made in development of the gra… more

Effect of Wavefront Error on 10^-7 Contrast Measurements

Description: We have measured a contrast of 6.5 {center_dot} 10{sup -8} from 10-25{lambda}/D in visible light on the Extreme Adaptive Optics testbed using a shaped pupil for diffraction suppression. The testbed was designed with a minimal number of high-quality optics to ensure low wavefront error and uses a phase shifting diffraction interferometer for metrology. This level of contrast is within the regime needed for imaging young Jupiter-like planets, a primary application of high-contrast imaging. We hav… more

Localized Corrosion of Alloy 22 -Fabrication Effects-FY05 Summary Report

Description: This report deals with the impact of fabrication processes on the localized corrosion behavior of Alloy 22 (N06022). The four fabrication processes that were analyzed are: (1) Surface stress mitigation of final closure weld, (2) Manufacturing of the mockup container, (3) Black annealing of the container and (4) Use of different heats of Alloy 22 for container fabrication. Immersion and Electrochemical tests performed in the laboratory are generally aggressive and do not represent actual reposit… more

Federal Excise Tax on Tires: Where the Rubber Meets the Road

Description: This report examines the history of the federal excise tax on tires. The excise tax on tires was first levied in 1918 mainly because of revenue needs brought about by World War I. The tax was reduced after the war, and then repealed in 1926. The levy was reintroduced during the Great Depression at a time when federal individual income tax revenues were plummeting, and was increased to help finance World War II. Today, the premise for the excise tax on tires is that heavier vehicles cause greate… more

Cryostat with Foil and MLI

Description: Induction cores are used to accelerate heavy ion beam array, which are built around the outer diameter of the cryostat housing the superconducting quadruple array. Compact cryostat is highly desirable to reduce the cost of the induction cores. Recent experiences in fabrication of a cryostat for single beam transport revealed that it is possible to reduce the spacing in the cryostat vacuum jacket by using low-emissivity thermal insulation material instead of conventional MLI. However, it is labo… more

Federal Real Property: Reliance on Costly Leasing to Meet New Space Needs Is an Ongoing Problem

Description: Testimony issued by the Government Accountability Office with an abstract that begins "In January 2003, GAO designated federal real property a high-risk area and issued an update on this area in January 2005. GAO identified the government's reliance on costly leased space as one of the major reasons for the high-risk designation. Other reasons included excess and deteriorated property, unreliable real property data, and the challenges associated with protecting these assets from terrorism. This… more

Materials Response Under Extreme Conditions

Description: Solid state experiments at extreme pressures, 10-100 GPa (0.1-1 Mbar) and strain rates (10{sup 6}-10{sup 8} s{sup -1}) are being developed on high-energy laser facilities. The goal is an experimental capability to test constitutive models for high-pressure, solid-state strength for a variety of materials. Relevant constitutive models are discussed, and our progress in developing a quasi-isentropic, ramped-pressure, shockless drive is given. Designs to test the constitutive models with experimen… more

OCRWM Science & Technology Program Materials Performance Targeted Thrust Fact Sheet

Description: In severe corrosive or abrasive environments, steel is rarely used since the range of properties available, in existing steels, are insufficient, resulting in the prevalent usage of either corrosion resistant materials like nickel based superalloys or abrasion resistant materials like tungsten carbide based hardmetals. Recently, a host of carbide based alloys including WC-Co-Cr, NiCr-Cr{sub 3}C{sub 2}, WC-Cr{sub 3}C{sub 2}-Ni etc. have been developed in an attempt to bridge the gap between prov… more
