Conical geometry for sagittal focusing as applied to X rays from synchrotrons (open access)

Conical geometry for sagittal focusing as applied to X rays from synchrotrons

The authors describe a method for simultaneously focusing and monochromatization of X rays from a fan of radiation having up to 15 mrad divergence in one dimension. This geometry is well suited to synchrotron radiation sources at magnifications of one-fifth to two and is efficient for X-ray energies between 3 and 40 keV (0.48 and 6.4 fJ). The method uses crystals bent to part of a cone for sagittal focusing and allows for the collection of a larger divergence with less mixing of the horizontal into the vertical divergence than is possible with X-ray mirrors. They describe the geometry required to achieve the highest efficiency when a conical crystal follows a flat crystal in a nondispersive two-crystal monochromator. At a magnification of one-third, the geometry is identical to a cylindrical focusing design described previously. A simple theoretical calculation is shown to agree well with ray-tracing results. Minimum aberrations are observed at magnifications near one. Applications of the conical focusing geometry to existing and future synchrotron radiation facilities are discussed.

Electricity savings from residential appliance standards in Sweden (open access)

Electricity savings from residential appliance standards in Sweden

This paper discusses the energy savings that could be obtained in Sweden by instituting specific standards for five appliances: Refrigerators, freezers, dishwashers, clothes washers, and clothes dryers. At the present time, Sweden has no minimum energy efficiency standards for residential appliances. This paper discusses the energy savings that could be obtained by instituting specific standards for five product types (refrigerators, freezers, dishwashers, clothes washers, and dryers) starting in 1995. A methodology similar to that used in analyses for the European Community was employed in this study. In the Swedish study, we used appliance test data developed by the Swedish consumer agency, Konsument Verket, to estimate new unit energy consumption for each product type. Shipments, saturations, energy use, and demographic data were input to a spreadsheet model that sums energy consumption for each product type over the period 1990--2010. Both a base case and a standards case scenario are simulated for each of the five appliance types. It was found that electricity use for these five products can be reduced by 12% over the time period from 1990--2010. Most of the energy savings come from instituting efficiency standards for refrigerators and freezers. For each product class type, the impact on manufacturer …

Structure and stability of microvoids in A-Si:H (open access)

Structure and stability of microvoids in A-Si:H

Microvoids appear to be universally present in a-Si:H as demonstrated by small angle X-ray scattering including the presence of microvoids in device quality glow discharge a-Si:H. We have studied the structural properties of these microvoids with molecular dynamics simulations. Using molecular dynamics simulations with classical potentials, we have created microvoids by removing Si and H atoms from a computer generated a-Si:H network. The internal surfaces of the microvoids were passivated with additional H atoms and the microvoids were fully relaxed. Microvoids over a limited range of sizes (5--90 missing atoms) were examined. We obtained a relaxed microvoid structure with no dangling bonds for a microvoid with 17 missing atoms, whereas other sizes examined produced less relaxed models with short H-H distances at the microvoid surface. The strains near the microvoid surface are described. The microvoid model was stable to local excitations on weak bonds in the vicinity of the microvoid.

The pp elastic scattering experiment at RHIC and polarization studies in the Coulomb Nuclear Interference region (open access)

The pp elastic scattering experiment at RHIC and polarization studies in the Coulomb Nuclear Interference region

We have examined the feasibility of measuring proton proton (pp) elastic scattering at small four momentum transfer t. The application of the measurement as a polarimeter in the Coulomb Nuclear Interference (CNI) region for polarized pp collisions is discussed. In addition, other fundamental polarization phenomena can be explored by making use of the same setup. The configuration of the lattice of the Relativistic Heavy Ion Collider (RHIC) which allows the measurement of scattering in CHI region is presented. The t range of the experiment is 0.0005 < t < 0.2(GeV/c)[sup 2].

The effects of internal fluctuations on a class of nonequilibrium statistical field theories (open access)

The effects of internal fluctuations on a class of nonequilibrium statistical field theories

A class of models with applications to swarm behavior as well as many other types of spatially extended complex biological and physical systems is studied. Internal fluctuations can play an active role in the organization of the phase structure of such systems. In particular, for the class of models studied here the effect of internal fluctuations due to finite size is a renormalized decrease in the temperature near the point of spontaneous symmetry breaking.

Neutral-current detection in the Sudbury Neutrino Observatory (open access)

Neutral-current detection in the Sudbury Neutrino Observatory

The Sudbury Neutrino Observatory (SNO) will have the capability of detecting all active species of neutrinos with energies greater than 2.2 MeV by the neutral-current disintegration of deuterium. The comparison of this rate with the rate of inverse beta decay of the deuteron will yield a nearly model-independent answer to the question of whether electron neutrinos from the sun oscillate into mu or tau neutrinos. The signal of a neutral-current interaction is the liberation of a free neutron in the heavy-water detector, and we discuss a technique employing [sup 3]He proportional counters for registering these neutrons, particularly from the standpoint of the ultra-low backgrounds needed.

[Synthetic and mechanistic investigation of olefin polymerization catalyzed by early transition metal compounds]

During the second year we continued to prepare and characterize organoyttrium and organoscandium compounds for use as catalysts for polymerizing simple olefins and diolefins. Simple, one-component systems are being pursued, suitable for chain initiation, propagation, and termination studies. This document is divided into: dicarbollide derivatives of scandium as potential catalysts; design, synthesis, and characterization of the first isospecific [alpha] olefin polymerization catalysts; polymerization of [alpha] olefins and 1,5- hexadiene using organoscandium catalysts; and attempted preparations of diastereomeric Nb and Ta olefin/hydride and olefin/alkyl derivatives.

Gas conversion opportunities in LILCO's commercial sector

This report presents the results of a preliminary investigation into opportunities for gas conservation in Long Island Lighting Company's commercial sector. It focusses on gas-fired heating equipment. Various sources of data are examined in order to characterize the commercial buildings and equipment in the service territory. Several key pieces of information necessary to predict savings potential are identified. These include the efficiencies and size distribution of existing equipment. Twenty-one specific conservation measures are identified and their applicability is discussed in terms of equipment size. Recommendations include improving the characterization of existing buildings and equipment, and developing a greater understanding of the savings and costs of conservation measures, and their interactions, especially in the middle size range of buildings and equipment.

Neutron stars and nuclei in the modified relativistic Hartree approximation (open access)

Neutron stars and nuclei in the modified relativistic Hartree approximation

The properties of neutron-rich matter and finite nuclei are in the modified relativistic Hartree approximation for several values of the renormalization scale, [mu], around the standard choice of [mu] equal to the nucleon mass, M. Observed neutron star masses do not effectively constrain the valve of [mu]. However, for finite nuclei the value [mu]/M=0.79, suggested by nuclear matter data, provides a good account of the bulk properties with a sigma mass of about 600 MeV. This value of [mu]/M renders the effective three- and four-body scalar self-couplings to be zero at 60% of equilibrium nuclear matter density, rather than in the vacuum. The matter part of the exchange diagram has little impact on the bulk properties of neutron stars.

Addressing the insider threat (open access)

Addressing the insider threat

Computers have come to play a major role in the processing of information vital to our national security. As we grow more dependent on computers, we also become more vulnerable to their misuse. Misuse may be accidental, or may occur deliberately for purposes of personal gain, espionage, terrorism, or revenge. While it is difficult to obtain exact statistics on computer misuse, clearly it is growing. It is also clear that insiders -- authorized system users -- are responsible for most of this increase. Unfortunately, their insider status gives them a greater potential for harm This paper takes an asset-based approach to the insider threat. We begin by characterizing the insider and the threat posed by variously motivated insiders. Next, we characterize the asset of concern: computerized information of strategic or economic value. We discuss four general ways in which computerized information is vulnerable to adversary action by the insider: disclosure, violation of integrity, denial of service, and unauthorized use of resources. We then look at three general remedies for these vulnerabilities. The first is formality of operations, such as training, personnel screening, and configuration management. The second is the institution of automated safeguards, such as single-use passwords, encryption, and biometric …

A very-low-Q diffractometer for an advanced spallation source (open access)

A very-low-Q diffractometer for an advanced spallation source

Proposals to build new, more powerful spallation sources and the introduction of advanced moderator concepts will result in neutron sources that are 20 times more luminous than the brightest available today. These developments provide opportunity and challenge to expand the capabilities of present low-Q instruments using new designs. A particularly interesting case is the design of an instrument capable of measurements to very low'' momentum transfer, say Q [approx] 0.0007 [Angstrom][sup [minus]1]. We consider an instrument to be built on a 20 Hz, 330 kW target and viewing a coupled liquid-hydrogen moderator. The instrument would use a frame-definition chopper to select a wavelength band suitable for the required Q-domain. Monte Carlo optimization of the geometry was performed by choosing the minimum observable Q always to be 0.0007 [Angstrom][sup [minus]1] and then maximizing intensity/variance at Q = 0.0020 [Angstrom][sup [minus]1] while maintaining reasonable constraints. The resulting design is 48 m long, with a maximum wavelength band 16.9 [Angstrom] [le] [lambda] [le] 20.5 [Angstrom]. The Monte Carlo simulations of instrument performance include wavelength-dependent effects from aluminum and fused silica windows, air, chopper opening and closing times and phase jitter, measured spectrum and detector efficiencies, sample transmission and multiple scattering, and gravity.

Dynamic impact and pressure analysis of the insensitive munitions container PA103 with modified design features (open access)

Dynamic impact and pressure analysis of the insensitive munitions container PA103 with modified design features

This report presents analytical analyses of the insensitive munitions container PA103, with modified design features for a static internal pressure of 500 psi and for a dynamic impact resulting from a 7-ft free fall onto a rigid surface. The modified design features addressed by the analyses were the inclusion of a score pattern on the container cylindrical body and a plastic plate (fuse) sandwiched between metal flanges on the container end. The objectives of both the pressure and impact analyses were to determine if the induced stresses at the score patterns in the cylindrical body of the container were sufficient to induce failure. Analytical responses of the container to the imposed loads were obtained with finite element analysis methodology. The computer codes ABAQUS and VEC/DYNA3D were used to obtain the results. Results of the pressure analysis indicate that failure of the container body would be expected to occur at the score pattern for a static internal pressure of 500 psi. Also, results from three impact orientations for a 7-ft drop indicate that membrane stresses in the vicinity of the score pattern are above critical crack growth stress magnitudes, especially at low ([minus]60[degrees]F) temperatures.

Advanced power systems featuring a closely coupled catalytic gasification carbonate fuel cell plant (open access)

Advanced power systems featuring a closely coupled catalytic gasification carbonate fuel cell plant

Pursuing the key national goal of clean and efficient uulization of the abundant domestic coal resources for power generation, a study was conducted with DOE/METC support to evaluate the potential of integrated gasification/carbonate fuel cell power generation systems. By closely coupling the fuel cell with the operation of a catalytic gasifier, the advantages of both the catalytic gasification and the high efficiency fuel cell complement each other, resulting in a power plant system with unsurpassed efficiencies approaching 55% (HHV). Low temperature catalytic gasification producing a high methane fuel gas offers the potential for high gas efficiencies by operating with minimal or no combustion. Heat required for gasification is provided by combination of recycle from the fuel cell and exothermic methanation and shift reactions. Air can be supplemented if required. In combination with internally reforming carbonate fuel cells, low temperature catalytic gasification can achieve very attractive system efficiencies while producing extremely low emissions compared to conventional plants utilizing coal. Three system configurations based on recoverable and disposable gasification catalysts were studied. Experimental tests were conducted to evaluate these gasification catalysts. The recoverable catalyst studied was potassium carbonate, and the disposable catalysts were calcium in the form of limestone and iron in …

Wave function calculations in finite nuclei (open access)

Wave function calculations in finite nuclei

One of the central problems in nuclear physics is the description of nuclei as systems of nucleons interacting via realistic potentials. There are two main aspects of this problem: (1) specification of the Hamiltonian, and (2) calculation of the ground (or excited) states of nuclei with the given interaction. Realistic interactions must contain both two- and three-nucleon potentials and these potentials have a complicated non-central operator structure consisting, for example, of spin, isospin and tensor dependencies. This structure results in formidable many-body problems in the computation of the ground states of nuclei. At Argonne and Urbana, the authors have been following a program of developing realistic NN and NNN interactions and the methods necessary to compute nuclear properties from variational wave functions suitable for these interactions. The wave functions are used to compute energies, density distributions, charge form factors, structure functions, momentum distributions, etc. Most recently they have set up a collaboration with S. Boffi and M. Raduci (University of Pavia) to compute (e,e[prime]p) reactions.

Nuclear Medicine Program progress report for quarter ending March 31, 1993

We have exploring the possibility of measuring urinary radioactivity as an index of pancreatic lipase activity after oral administration of a new triglyceride containing a radioactive iodine-1 25-labeled fatty acid moiety. The new agent, 1,2-dipalmitoyl-3[15-(p-iodophenyl)pentandecan-l-oyl]-racglycerol (1,2-Pal-3-IPPA), was prepared by the thallation-iodide displacement method. Following oral gavage of the radioiodinated triglyceride to rats, about 30% of the administered activity was excreted in 24 hours in the urine. In normal human controls an higher urinary excretion (of about 75% was observed. In this report, we describe an evaluation of the metabolites excreted in the urine and the chemical species stored in adipose from rats. The urine activity co-chromatographed with hippuric acid by TLC indicating conjugation of the IPPA metabolites. Release of the acidic components from the conjugated excretory products by acid hydrolysis of the urine provided the radioactive acidic IPPA metabolites. Analysis of the Folch extracts of fat samples from rats demonstrated that the radioactive components co-chromatographed In the triglyceride region. Recent studies in patients with compromised pancreatic exocrine function have demonstrated significantly decreased 24 hr. urinary excretion of about 25%, following oral administration of [1 -1 31]-1,2-Pal-3-IPPA. Thus, urine analysis after oral administration of [I -1 31]-1,2-Pal-3-IPPA may be a simple, …

Luminance controlled pupil size affects Landolt C task performance (open access)

Luminance controlled pupil size affects Landolt C task performance

Subjects judged the orientation of a 2 min. gap Landolt C located at a distance of 2.4 m. The stimuli were presented in central vision on a CRT, at low to medium contrast. The effects of varying the spectrum and luminance of surround lighting were assessed on both pupil size (measured using infrared pupillometry during task performance) and task accuracy. The task display was protected from the surround lighting, so that its luminance and contrast could be varied independently of the changes in the surround lighting. Indirect surround illumination was provided by either two illuminants of very different scotopic spectral content but with the same photopic luminance (Experiments 1 and 3), or by using the same illuminant at two different luminance levels (Experiment 2). In Experiment 3, the effect of changing surround spectrum was compared to the effect of varying task background luminance between 12 cd/m[sup 2] and 73 cd/m[sup 2]. In all experiments, scotopically enhanced surround lighting produced pupil areas which were reduced by almost 50% in comparison with surround lighting with relatively less scotopic luminance. Concomitantly there was improvement in Landolt C task performance with the scotopically enhanced surround lighting at all contrast and luminance levels. In these …

Surveillance of Site A and Plot M (open access)

Surveillance of Site A and Plot M

The results of the environmental surveillance program conducted at Site A/Plot M in the Palos Forest Preserve area for CY 1992 are presented. The surveillance program is the ongoing remedial action that resulted from the 1976--1978 radiological characterization of the site. That study determined that very low levels of hydrogen-3 (as tritiated water) had migrated from the burial ground and were present in two nearby hand-pumped picnic wells. The current program consists of sample collection and analysis of air, surface and subsurface water, and bottom sediment. The results of the analyses are used to (1) determine the migration pathway of water from the burial ground (Plot M) to the hand-pumped picnic wells, (2) establish if buried radionuclides other than hydrogen-3 have migrated, and (3) generally characterize the radiological environment of the area. Hydrogen-3 in the Red Gate Woods picnic wells was still detected this year, but the average and maximum concentrations were significantly less than found earlier. Tritiated water continues to be detected in a number of wells, boreholes, dolomite holes, and a surface stream. For many years it was the only radionuclide found to have migrated in measurable quantities. Analyses since 1984 have indicated the presence of low levels …

ARIES tokamak reactor study (open access)

ARIES tokamak reactor study

This report examines the feasibility of a standard poloidal diverter design for ARIES- 2/4 with the determination of the peak thermal loading on, and the plasma temperature facing a poloidal double null diverter. The ARIES-2/4 reactors produce 2,141 MW of fusion power of which 1712 MW is contained in the neutron channel. Of the remaining 429 MW of charged particle power, 47 MW is radiated from the core by bremsstrahlung and synchrotron modes to the vessel walls. The remaining 382 MW of charged particle or transport power crosses the core/edge interface. The fact that the bulk of the power is contained in the neutron channel makes the application of a poloidal divertor possible. The ARIES-2/4 diverter constraints for peak heat load and peak particle temperature are set by current technology and materials knowledge. Divertor geometry constraints are imposed by the plasma equilibrium and the 2/4 vacuum vessel. The diverter heat load and plasma temperatures are determined from edge particle and energy balances. These balances are important characteristics of the plasma edge because the transport power from the plasma core must pass through the edge and be deposited on tokamak components. The Braams' B2 code is a multifluid ion and electron …

Development of a neural net paradigm that predicts simulator sickness (open access)

Development of a neural net paradigm that predicts simulator sickness

A disease exists that affects pilots and aircrew members who use Navy Operational Flight Training Systems. This malady, commonly referred to as simulator sickness and whose symptomatology closely aligns with that of motion sickness, can compromise the use of these systems because of a reduced utilization factor, negative transfer of training, and reduction in combat readiness. A report is submitted that develops an artificial neural network (ANN) and behavioral model that predicts the onset and level of simulator sickness in the pilots and aircrews who sue these systems. It is proposed that the paradigm could be implemented in real time as a biofeedback monitor to reduce the risk to users of these systems. The model captures the neurophysiological impact of use (human-machine interaction) by developing a structure that maps the associative and nonassociative behavioral patterns (learned expectations) and vestibular (otolith and semicircular canals of the inner ear) and tactile interaction, derived from system acceleration profiles, onto an abstract space that predicts simulator sickness for a given training flight.

Appendix SET-TMP-PT of the Experiment Operating Specification for the Savannah River One-Fourth Linear Scale, One-Sixth Sector, Tank/Muff/Pump (TMP) Separate Effects Tests (SET) experiment series

The Savannah River One-Fourth Linear Scale, One-Sixth Sector, Tank-Muff-Pump (TMP) Separate Effects Tests (SET) are being conducted by the Idaho National Engineering Laboratory to investigate Savannah River Site (SRS) production reactor tank, muff, pump suction, and pump hydraulic response phenomena for large break loss-of-coolant accident (LBLOCA) scenarios. The test series consists of experiments representing a range of hydraulic conditions and geometries which bound those anticipated for LBLOCAs in SRS reactors. Data from these experiments will be examined to identify important hydraulic phenomena with the objective of providing data for benchmarking code calculations. Information obtained from the SET series will also expand the SRS data base on reactor LBLOCA events. Due to inherent scaling distortions and facility limitations, the results of experiments in the SET series will not be precise replications of full-scale Savannah River Site production reactor (SRSPR) response, but will provide hydraulic behavior sufficiently representative of full-scale SRSPR behavior to preserve important hydraulic phenomena and satisfy test objectives. This document is Appendix SET-TMP-PT of the Experiment Operating Specification for the third set of experiments in the SET series. It contains information on experiment operation and facility configuration necessary to meet the key objectives stated in the bingham pump formal …
