Application of the Pegasus II Pulsed-Power Facility to the Study of Inertial Instability and Fracture of Cylindrical Tubes of Solid Aluminum

Description: Understanding the surface stability of metals undergoing dynamic fracture at shock breakout is important to several applications in metals processing. The advantages of using the Pegasus II facility to investigate the phenomena occurring at shock break out are described. As an example of the data collected, we concentrate on brief descriptions of two experiments that compared the tensile failure, i.e. ''spall'', patterns in the presence of sinusoidal perturbations seeded on the free inner surfa… more

Colorado Homeowner Preferences on Energy and Environmental Policy

Description: This survey inquiring into Colorado homeowners' preferences on energy and environmental policy shows that more-affluent, married Colorado single-family homeowners are somewhat favorable to utility restructuring; want to see green power developed; prefer to share the costs broadly by various means; are willing to pay slightly higher electricity rates to develop renewable sources of electricity; and believe that utility customers don't have enough choice in their electric service today.

Cosmic ray sun shadow in Soudan 2 underground muon flux.

Description: The absorption of cosmic rays by the sun produces a shadow at the earth. The angular offset and broadening of the shadow are determined by the magnitude and structure of the interplanetary magnetic field (IPMF) in the inner solar system. The authors report the first measurement of the solar cosmic ray shadow by detection of deep underground muon flux in observations made during the entire ten-year interval 1989 to 1998. The sun shadow varies significantly during this time, with a 3.3{sigma} sha… more

Cygnus X-3 revisited: 10 years of muon and radio observations.

Description: The Soudan 2 deep underground tracking calorimeter has recorded cosmic ray muon tracks from the direction of the galactic x-ray binary Cygnus X-3 on most transits during the interval 1989-1998. We analyze these events in the context of previous reports of Cygnus X-3-related muon flux during major radio flares of that source. We find some evidence for excess flux during a small number of transits coincident with major radio flares. We also find an indication that these events maybe distributed a… more

Data Analysis and reduction in Hanford's corrosion monitoring systems

Description: A project to improve the Hanford Site's corrosion monitoring strategy was started in 1995. The project is designed to integrate EN-based corrosion monitoring into the site's corrosion monitoring strategy. In order to monitor multiple tanks, a major focus of this project has been to automate the data collection and analysis process. Data collection and analysis from the early EN corrosion monitoring equipment (241-AZ-101 and 241-AN-107) was primarily performed manually by a trained operator skil… more

Data quality objectives for TWRS privatization phase 1: tank waste transfer control

Description: The Phase 1 privatization contract (DOE-RL 1996) requires that the Project Hanford Management Contractors, on behalf of the U.S. Department of Energy, Richland Operations Office, deliver waste feed in appropriate quantities and composition on schedule. The Feed Process Management Team (FPMT) was created with responsibility for establishing requirements, identifying and recommending baseline change control, assuring configuration management of tank contents (e.g., feed pedigrees), and requiring … more

Dielectrophoretic manipulation of particles for use in microfluidic devices

Description: Amplification and hybridization of DNA are commonly used techniques to verify the presence of a specific DNA sequence in a test sample. Automatic sample handling to concentrate and purify sample prior to amplification is desirable both from the cost standpoint and from the standpoint of reducing the possibility of sample contamination. This paper explores the use of the dielectrophoretic force to manipulate DNA, Bacillus globigii spores, and Erwinia herbicola bacteria to provide concentration a… more

Double-shell tank annulus pumping alternative evaluation

Description: This engineering evaluation compares five alternative schemes for maintaining emergency annulus pumping equipment in a reliable condition. The five schemes are: (1) continue status quo; (2) periodic pump removal and run-in; (3) periodic in-place limited maintenance; (4) uninstalled ready spares; and (5) expanded mission of Single-Shell Tank Emergency Pumping Trailer. Each alternative is described, the pros and cons identified, and rough order of magnitude life-cycle costs computed. The alternat… more

Experimental Bench Mark Data for ALEGRA Code Validations

Description: In this study experiments of increasing complexity have been conducted to provide a data base for validating features of the Arbitrary Lagrangian Eulerian Grid for Research Applications (ALEGRA) code over a broad range of strain rates with overlapping diagnostics that encompass multiple responses. This range encompasses strain rates characteristic of shock-wave propagation (10<sup>7</sup>/s) and those chameteristics of structural response (10<sup>2</sup>/s). The tests matrix consists of two exp… more

Final Results from the High-Current, High-Action Closing Switch Test Program at Sandia National Laboratories

Description: We tested a variety of high-current closing switches for lifetime and reliability on a dedicated 2 MJ, 500 kA capacitor bank facility at Sandia National Laboratories. Our interest was a switch capable of one shot every few minutes, switching a critically damped, DC-charged 6.2 mF bank at 24 kV, with a peak current of 500 kA. The desired lifetime is 24 thousand shots. Typical of high-energy systems, particularly multi-module systems, the primary parameters of interest related to the switch are: … more

High-accuracy calibration of an adaptive optics system using a phase shifting diffraction interferometer

Description: A phase-shifting diffraction interferometer (PSDI) has been integrated into an adaptive optics (AO) system developed by LLNL for use on the three meter Shane telescope at Lick Observatory. The interferometer is an all fiber optic design, which is extremely compact. It is useful for calibrating the control sensors, measuring the aberrations of the entire AO optical train, and measuring the influence functions of the individual actuators on the deformable mirror. The PSDI is particularly well sui… more
