Labs21 Environmental Performance Criteria: Toward 'LEED (trademark) for Labs' (open access)

Labs21 Environmental Performance Criteria: Toward 'LEED (trademark) for Labs'

Laboratory facilities present a unique challenge for energy efficient and sustainable design, with their inherent complexity of systems, health and safety requirements, long-term flexibility and adaptability needs, energy use intensity, and environmental impacts. The typical laboratory is about three to five times as energy intensive as a typical office building and costs about three times as much per unit area. In order to help laboratory stakeholders assess the environmental performance of their laboratories, the Labs21 program, sponsored by the US Environmental Protection Agency and the US Department of Energy, is developing the Environmental Performance Criteria (EPC), a point-based rating system that builds on the LEED(TM) rating system. Currently, LEED(TM) is the primary tool used to rate the sustainability of commercial buildings. However, it lacks some attributes essential to encouraging the application of sustainable design principles to laboratory buildings. Accordingly, the EPC has additions and modifications to the prerequisites and credits in each of the six sections of LEED(TM). It is being developed in a consensus-based approach by a diverse group of architects, engineers, consulting experts, health & safety personnel and facilities personnel. This report describes the EPC version 2.0, highlighting the underlying technical issues, and describes implications for the development …

Engineering properties of superhard films with ion energy and post-deposition processing (open access)

Engineering properties of superhard films with ion energy and post-deposition processing

Recent developments in plasma synthesis of hard materials using energetic ions are described. Metal Plasma Immersion Ion Implantation and Deposition (MePIIID) has been used to prepare several hard films: from diamondlike carbon (DLC) to carbides, from nitrides to oxides. The energy of the depositing species is controlled to maximize adhesion as well as to change the physical and chemical properties of the films. Adhesion is promoted by the creation of a graded interface between the film and the substrate. The energy of the depositing ions is also used to modify and control the intrinsic stresses and the microstructure of the films. The deposition is carried out at room temperature, which is important for temperature sensitive substrates. A correlation between intrinsic stresses and the energetics of the deposition is presented for the case of DLC films, and means to reduce stress levels are discussed.

Tracking of three variants of transition-free lattices for a proton driver (open access)

Tracking of three variants of transition-free lattices for a proton driver

Transition-free lattices are favored as possible realization of proton drivers. Several variants have been proposed, some of which have considerably different behavior. One of the main quantities used to characterize this behavior is the short term dynamic aperture (DA). In this note we study three different variants of such lattices, and show that the differences in DA among the lattices essentially disappear as soon as magnet multipole errors are included in the simulation. The tracking results can be understood in terms of the normal form based amplitude dependent tune shift and resonance strength coefficients.

Passive correction of the persistent current effect in Nb3Sn accelerator magnets (open access)

Passive correction of the persistent current effect in Nb3Sn accelerator magnets

Superconducting accelerator magnets must provide a uniform field during operation. However, the field quality significantly deteriorates due to persistent currents induced in superconducting filaments. This effect is especially large for the Nb{sub 3}Sn conductor being implemented in the next generation of accelerator magnets. A simple and inexpensive method of passive correction of the persistent current effect was developed and experimentally verified. This paper describes numerical simulations of the passive correctors and reports the test results.

Source Parameters from Identified Hadron Spectra and HBT Radii for Au-Au Collisions at (Square Root)SNN=200 GeV in PHENIX (open access)

Source Parameters from Identified Hadron Spectra and HBT Radii for Au-Au Collisions at (Square Root)SNN=200 GeV in PHENIX

The characteristics of the particle emitting source are deduced from low p{sub T} identified hadron spectra ((m{sub T}-m0) < 1 GeV) and HBT radii using a hydrodynamic interpretation. From the most peripheral to the most central data, the single particle spectra are fit simultaneously for all {pi}{sup {+-}}, K{sup {+-}}, and {bar p}/p using the parameterization in [1] and assuming a linear transverse flow profile. Within the systematic uncertainties, the expansion parameters T{sub fo} and {beta}{sub T}, respectively decrease and increase with the number of participants, saturating for both at mid-centrality. The expansion using analytic calculations of the k{sub T} dependence of HBT radii in [2] is fit to the data but no {chi}{sup 2} minimum is found.

Reservoir Characterization: Electromagnetic Imaging of CO2 for EOR Processes (open access)

Reservoir Characterization: Electromagnetic Imaging of CO2 for EOR Processes

Lawrence Livermore National Laboratory is currently involved in a long term study using time-lapse multiple frequency electromagnetic (EM) imaging at a carbon dioxide (CO{sub 2}) enhanced oil recovery (EOR) site in the San Joaquin Valley, California. The impetus for this proposed research project is to develop the ability to image subsurface CO{sub 2} during EOR processes while simultaneously discriminating between background heavy petroleum and water deposits. Using field equipment developed at Lawrence Livermore National Laboratory in prior imaging studies of EOR water and steam injection, this research uses multiple field deployments to acquire subsurface image snapshots of the CO{sub 2} injection and displacement. Laboratory research, including electrical and transport properties of fluid and CO{sub 2} in saturated materials, uses core samples from drilling, as well as samples of injection and formation fluid provided by industrial partners on-site. Our two-fold approach to combine laboratory and field methods in imaging a pilot CO{sub 2} sequestration EOR site using the cross-borehole EM technique is to (1) improve the inversion process in CO{sub 2} studies by coupling field results with petrophysical laboratory measurements and (2) focus on new gas interpretation techniques of the field data using multiple frequencies and low noise data processing techniques. …

Tracing Fuel Component Carbon in the Emissions from Diesel Engines (open access)

Tracing Fuel Component Carbon in the Emissions from Diesel Engines

The addition of oxygenates to diesel fuel can reduce particulate emissions, but the underlying chemical pathways for the reductions are not well understood. While measurements of particulate matter (PM), unburned hydrocarbons (HC), and carbon monoxide (CO) are routine, determining the contribution of carbon atoms in the original fuel molecules to the formation of these undesired exhaust emissions has proven difficult. Renewable bio-derived fuels (ethanol or bio-diesel) containing a universal distribution of contemporary carbon are easily traced by accelerator mass spectrometry (AMS). These measurements provide general information about the emissions of bio-derived fuels. Another approach exploits synthetic organic chemistry to place {sup 14}C atoms in a specific bond position in a specific fuel molecule. The highly labeled fuel molecule is then diluted in {sup 14}C-free petroleum-derived stock to make a contemporary petroleum fuel suitable for tracing. The specific {sup 14}C atoms are then traced through the combustion event to determine whether they reside in PM, HC, CO, CO{sub 2}, or other emission products. This knowledge of how specific molecular structures produce certain emissions can be used to refine chemical-kinetic combustion models and to optimize fuel composition to reduce undesired emissions. Due to the high sensitivity of the technique and the lack …

Simulation of Chamber Transport for Heavy-Ion Fusion (open access)

Simulation of Chamber Transport for Heavy-Ion Fusion

Beams for heavy-ion fusion (HIF) are expected to require substantial neutralization in a target chamber. Present targets call for higher beam currents and smaller focal spots than most earlier designs, leading to high space-charge fields. Collisional stripping by the background gas expected in the chamber further increases the beam charge. Simulations with no electron sources other than beam stripping and background-gas ionization show an acceptable focal spot only for high ion energies or for currents far below the values assumed in recent HIF power-plant scenarios. Much recent research has, therefore, focused on beam neutralization by electron sources that were neglected in earlier simulations, including emission from walls and the target, photoionization by radiation from the target, and pre-neutralization by a plasma generated along the beam path. The simulations summarized here indicate that these effects can significantly reduce the beam focal-spot size.

Electron Beam Production and Characterization for the PLEIADES Thomson X-ray Source

We report on the performance of an S-band RF photocathode electron gun and accelerator for operation with the PLEIADES Thomson x-ray source at LLNL. Simulations of beam production, transport, and focus are presented. It is shown that a 1 ps, 500 pC electron bunch with a normalized emittance of less than 5 {pi}mm-mrad can be delivered to the interaction point. Initial electron measurements are presented. Calculations of expected x-ray flux are also performed, demonstrating an expected peak spectral brightness of 10{sup 20} photons/s/mm{sup 2}/mrad{sup 2}/0.1% bandwidth. Effects of RF phase jitter are also presented, and planned phase measurements and control methods are discussed.

Oral History Interview with Steve Weiner, October 14, 2002

The National Museum of the Pacific War presents an oral interview with Steve Weiner. Weiner graduated from high school in 1935 and attended UCLA for a period of time before graduated from the University of Pittsburg. He entered the cadet training program in 1940 and was sent to Randolph Field in San Antonio. Upon washing out of the program, he was assigned to the 86th Observation Squadron as communications officer at Bellows Field, Hawaii. He recalls 7 December 1941 when a B-17 bomber crash landed on Bellow Field and being told by the crewmembers that they had been attacked. Later his group was strafed by Japanese planes. They were told to draw weapons and prepare for invasion by land forces. He tells of Corporal David Akui bringing the commander of a Japanese midget submarine (HA-19) to him as a captive. He describes in detail the appearance of the commander, Kazuo Sakamaki, and his interaction with him before turning him over to higher authorities. He relates how he communicated with Sakamaki after the war and of meeting him in 1991. [HA-19 is on display at The National Museum of the Pacific War.] In late 1941, Weiner was assigned as officer in …

Anomalous momentum dependence of the quasiparticle scattering ratein overdoped Bi2Sr2CaCu2O8 (open access)

Anomalous momentum dependence of the quasiparticle scattering ratein overdoped Bi2Sr2CaCu2O8

The question of the anisotropy of the electron scattering in high temperature superconductors is investigated using high resolution angle-resolved photoemission data from Pb-doped Bi2Sr2CaCu2O8(Bi2212) with suppressed superstructure. The scattering rate of low energy electrons along two bilayer split pieces of the Fermi surface is measured (via the quasiparticle peak width), and no increase of scattering towards the antinode (Pi,0) region is observed, contradicting the expectation from Q=(Pi, Pi) scattering. The results put a limit on the effects of Q=(Pi, Pi) scattering on the electronic structure of this overdoped superconductor with still very high Tc.
