Brittle-Ductile Relaxation Kinetics of Strained AlGaN/GaN (open access)

Brittle-Ductile Relaxation Kinetics of Strained AlGaN/GaN

The authors have directly measured the stress evolution during metal organic chemical vapor deposition of AlGaN/GaN heterostructures on sapphire. In situ stress measurements were correlated with ex situ microstructural analysis to directly determine a critical thickness for cracking and the subsequent relaxation kinetics of tensile-strained Al{sub x}Ga{sub 1{minus}x}N on GaN. Cracks appear to initiate the formation of misfit dislocations at the AlGaN/GaN interface, which account for the majority of the strain relaxation.

Database system for management of health physics and industrial hygiene records.

This paper provides an overview of the Worker Protection System (WPS), a client/server, Windows-based database management system for essential radiological protection and industrial hygiene. Seven operational modules handle records for external dosimetry, bioassay/internal dosimetry, sealed sources, routine radiological surveys, lasers, workplace exposure, and respirators. WPS utilizes the latest hardware and software technologies to provide ready electronic access to a consolidated source of worker protection.

Effect of shadowing on initial conditions, transverse energy and hard probes in ultrarelativistic heavy ion collisions (open access)

Effect of shadowing on initial conditions, transverse energy and hard probes in ultrarelativistic heavy ion collisions

The effect of shadowing on the early state of ultrarelativistic heavy ion collisions is investigated along with transverse energy and hard process production, specifically Drell-Yan, J/psi, and Upsilon production. We choose several parton distributions and parameterizations of nuclear shadowing, as well as the spatial dependence of shadowing, to study the influence of shadowing on relevant observables. Results are presented for Au+Au collisions at sqrt(s{sub NN}) = 200 GeV and Pb+Pb collisions at sqrt(s{sub NN}) =5.5 TeV.

FEMP case study: Regional super ESPC saves energy and dollars at NASA Johnson Space Center (open access)

FEMP case study: Regional super ESPC saves energy and dollars at NASA Johnson Space Center

This case study describes the new energy-efficient equipment being installed at NASA Johnson Space Center in Houston, Texas, to save nearly $2 million per year in energy and utility costs. The work is being done under a delivery order by Honeywell, Inc., as part of a US Department of Energy ``super'' regional energy savings performance contract, or Super ESPC. These are streamlined contracts that allow Federal agencies to contract with competitively selected energy service companies in their region for a variety of energy- and water-efficient products and services. The service companies pay up-front capital costs and are reimbursed with part of the agency's utility cost savings. In this work, NASA Johnson Space Center will get new energy-efficient lighting and compressed-air systems, water-conserving fixtures, and improved controls.

Field demonstration of the ICE 250{trademark} Cleaning System (open access)

Field demonstration of the ICE 250{trademark} Cleaning System

The ICE 250{trademark} Cleaning System was engineered to convert water into small ice particles for use in cleaning and decontamination applications. Ice crystals are produced in a special icemaker and pressured through a hose-nozzle onto the surface to be cleaned. The Rocky Mountain Oilfield Testing Center and Ice Cleaning Systems, Inc., conducted a test of this system at Naval Petroleum Reserve No. 3 to evaluate the system's cleaning capabilities in an oil field environment. Equipment cleaned included an oil storage tank, a rod pumping unit, a road grader, and a wellhead. Contaminants were unrefined sour crude oil, hydraulic fluid, paraffin, and dirt, occurring separately and as mixtures. In all four demonstration cleaning tasks, the ICE 250 System effectively removed surface contaminant mixtures in a timely manner and left no oily residue. A minimal amount of waste moisture was generated, thereby reducing cleanup and disposal costs.

High Efficiency Release Targets for Use at ISOL Facilities: Computational Design (open access)

High Efficiency Release Targets for Use at ISOL Facilities: Computational Design

This report describes efforts made at the oak Rklge NatiOnrd Laboratory to design high- efficiency-release targets that simultaneously incorporate the short diffusion lengths, high permeabilities, controllable temperatures, and heat-removal properties required for the generation of useful radioactive ion beam (RIB) intensities for nuclear physics and astrophysics research using the isotope separation on-line (ISOL) technique. Short diffusion lengths are achieved either by using thin fibrous target materials or by coating thin layers of selected target material onto low-density carbon fibers such as reticulated-vitreous-carbon fiber (RVCF) or carbon-bonded-carbon fiber (CBCF) to form highly permeable composite target matrices. Computational studies that simulate the generation and removal of primary beam deposited heat from target materials have been conducted to optimize the design of targetheat-sink systems for generating RIBs. The results derived from diffusion release-rate simulation studies for selected targets and thermal analyses of temperature distributions within a prototype targetlheat-sink system subjected to primary ion beam irradiation will be presented in this report.

Hypersonic ground test capabilities for T and E testing above mach 8 ''a case where S and T meets T and E'' (open access)

Hypersonic ground test capabilities for T and E testing above mach 8 ''a case where S and T meets T and E''

Simulation of hypersonic flight in ground test and evaluation (T and E) facilities is a challenging and formidable task, especially to fully duplicate the flight environment above approximately Mach 8 for most all hypersonic flight systems that have been developed, conceived, or envisioned. Basically, and for many years, the enabling technology to build such a ground test wind tunnel facility has been severely limited in the area of high-temperature, high-strength materials and thermal protection approaches. To circumvent the problems, various approaches have been used, including partial simulation and use of similarity laws and reduced test time. These approaches often are not satisfactory, i.e. operability and durability testing for air-breathing propulsion development and thermal protection development of many flight systems. Thus, there is a strong need for science and technology (S and T) community involvement in technology development to address these problems. This paper discusses a specific case where this need exists and where significant S and T involvement has made and continues to make significant contributions. The case discussed will be an Air Force research program currently underway to develop enabling technologies for a Mach 8-15 hypersonic true temperature wind tunnel with relatively long run time. The research is based …

Laser Assisted Plasma Arc Welding (open access)

Laser Assisted Plasma Arc Welding

Experiments have been performed using a coaxial end-effecter to combine a focused laser beam and a plasma arc. The device employs a hollow tungsten electrode, a focusing lens, and conventional plasma arc torch nozzles to co-locate the focused beam and arc on the workpiece. Plasma arc nozzles were selected to protect the electrode from laser generated metal vapor. The project goal is to develop an improved fusion welding process that exhibits both absorption robustness and deep penetration for small scale (< 1.5 mm thickness) applications. On aluminum alloys 6061 and 6111, the hybrid process has been shown to eliminate hot cracking in the fusion zone. Fusion zone dimensions for both stainless steel and aluminum were found to be wider than characteristic laser welds, and deeper than characteristic plasma arc welds.
