B-physics at RHIC: An opportunity

B physics provides a unique window for investigation and confirmation of our picture of CP violation, as well as an opportunity to explore physics beyond the Standard Model. Because of this richness of physics, programs for the study of the B sector are in progress or under development at most of the major facilities for high energy physics in the world. In this note we suggest that a B program at the RHIC facility at BNL could provide timely and complementary information to our understanding of physics within and beyond the Standard Model.

Hydrogen transport and storage in engineered glass microspheres (open access)

Hydrogen transport and storage in engineered glass microspheres

New, high-strength, hollow, glass microspheres filled with pressurized hydrogen exhibit storage densities which make them attractive for bulk hydrogen storage and transport. The hoop stress at failure of our engineered glass microspheres is about 150,000 psi, permitting a three-fold increase in pressure limit and storage capacity above commercial microspheres, which fail at wall stresses of 50,000 psi. For this project, microsphere material and structure will be optimized for storage capacity and charge/discharge kinetics to improve their commercial practicality. Microsphere production scale up will be performed, directed towards large-scale commercial use. Our analysis relating glass microspheres for hydrogen transport with infrastructure and economics` indicate that pressurized microspheres can be economically competitive with other forms of bulk rail and truck transport such as hydride beds, cryocarbons and pressurized tube transports. For microspheres made from advanced materials and processes, analysis will also be performed to identify the appropriate applications of the microspheres considering property variables, and different hydrogen infrastructure, end use, production and market scenarios. This report presents some of the recent modelling results for large beds of glass microspheres in hydrogen storage applications. It includes plans for experiments to identify the properties relevant to large-bed hydrogen transport and storage applications, of the …

Particle Motion in Crystalline Beams (open access)

Particle Motion in Crystalline Beams

Studying the possibility of storing a low emittance (or ``cooled``) beam of charged particles in a storage ring, the authors are faced with the effect of space charge by which particles are repelled and influence each others` motion. The correct evaluation of the space-charge effects is important to determine the attainment and properties of Crystalline Beams, a phase transition which intense beams of ions can undergo when cooling is applied. In this report they derive the equations of motion of a particle moving under the action of external resorting forces generated by the magnets of the storage ring, and of the electromagnetic fields generated by the other particles. The motion in every direction is investigated: in the longitudinal, as well as vertical and horizontal direction. The external forces are assumed to be linear with the particle displacement from the reference orbit. The space-charge forces are comparable in magnitude to the external focusing forces. The equations of motion so derived are then used to determine confinement and stability conditions for the attainment of Crystalline Beams, using transfer matrices.

Radiation effects in polymers for plastic scintillation detectors (open access)

Radiation effects in polymers for plastic scintillation detectors

Radiation damage studies were performed on polystyrene and poly(vinyltoluene) samples containing different concentrations of either an antioxidant (A O-2) or a plasticizer (PP-4). In addition, parallel studies were carried out utilizing samples of these polymers prepared in the presence of cross-linking agents such as NPG, HDA, and DVB. The samples were irradiated using a {sup 60} Co source to total doses of 1 and 10 Mrad, at a dose rate of approximately 1 Mrad/h. Transmittance measurements were recorded before and immediately after irradiation, and after oxygen annealing. These experiments showed that none of these agents improved the radiation resistance of polystyrene and poly(vinyltoluene) with regard to their optical properties.

Summary of safeguards interactions between Los Alamos and Chinese scientists (open access)

Summary of safeguards interactions between Los Alamos and Chinese scientists

Los Alamos has been collaborating since 1984 with scientists from the Chinese Institute of Atomic Energy (CIAE) to develop nuclear measurement instrumentation and safeguards systems technologies that will help China support implementation of the nonproliferation treaty (NPT). To date, four Chinese scientists have visited Los Alamos, for periods of six months to two years, where they have studied nondestructive assay instrumentation and learned about safeguards systems and inspection techniques that are used by International Atomic Energy Agency (IAEA) inspectors. Part of this collaboration involves invitations from the CIAE to US personnel to visit China and interact with a larger number of Institute staff and to provide a series of presentations on safeguards to a wider audience. Typically, CIAE scientists, Beijing Institute of Nuclear Engineering (BINE) staff, and officials from the Government Safeguards Office attend the lectures. The BINE has an important role in developing the civilian nuclear power fuel cycle. BINE is designing a reprocessing plant for spent nuclear fuel from Chinese nuclear Power reactors. China signed the nonproliferation treaty in 1992 and is significantly expanding its safeguards expertise and activities. This paper describes the following: DOE support for US and Chinese interactions on safeguards; Chinese safeguards; impacts of US-China …

Investigation of Moisture-Induced Embrittlement of Iron Aluminides. Interim Report (open access)

Investigation of Moisture-Induced Embrittlement of Iron Aluminides. Interim Report

Alloy FA-129 undergoes an increase in crack propagation rate and a loss of fracture toughness in moisture-bearing and hydrogen gas environments. A similar effect is seen on ductility of FA-129 in tensile tests. The embrittling effect in air is attributed to oxidation of aluminum in the alloy by water vapor to produce Al{sub 2}O{sub 3} and hydrogen gas. Alloy FAP-Y, which is disordered and contains only 16 a%Al is embrittled by hydrogen gas in a manner similar to that of FA-129. However, laboratory air had little effect on the crack growth rates, fracture toughness, or tensile ductility. The lower aluminum content apparently is insufficient to induce the Al-H{sub 2}O reaction. TEM and SEM analyses of microstructure and fracture surfaces were consistent with the change in fracture toughness with order and environment. Testing at elevated temperatures reduces crack growth rates in FA-129, and increases fracture toughness and ductility. This is consistent with the well documented peak in hydrogen embrittlement in structural alloys at or near room temperature. Elevated temperature affects the degree of embrittlement in a complex manner, possibly changing the rates of several of the processes involved.

MSW to hydrogen (open access)

MSW to hydrogen

LLNL and Texaco are cooperatively developing a physical and chemical treatment method for the preparation and conversion of municipal solid waste (MSW) to hydrogen by gasification and purification. The laboratory focus will be on pretreatment of MSW waste in order to prepare a slurry of suitable viscosity and heating value to allow efficient and economical gasification and hydrogen production. Initial pretreatment approaches include (1) hydrothermal processing at saturated conditions around 300 C with or without chemical/pH modification and (2) mild dry pyrolysis with subsequent incorporation into an appropriate slurry. Initial experiments will be performed with newspaper, a major constituent of MSW, prior to actual work with progressively more representative MSW samples. Overall system modeling with special attention to energy efficiency and waste water handling of the pretreatment process will provide overall guidance to critical scale-up parameters. Incorporation of additional feed stock elements (e.g., heavy oil) will be evaluated subject to the heating value, viscosity, and economics of the MSW optimal slurry for hydrogen production. Ultimate scale-up of the optimized process will provide sufficient material for demonstration in the Texaco pilot facility; additional long term objectives include more detailed economic analysis of the process as a function of technical parameters and …

Fundamental mechanisms in flue gas conditioning. Quarterly report, January 1994--March 1994 (open access)

Fundamental mechanisms in flue gas conditioning. Quarterly report, January 1994--March 1994

We are currently performing a series of pilot-scale tests designed to determine the effects that adsorbed water has on fabric filtration and electrostatic precipitation of entrained fly ash particles in actual flue gas environments. We are investigating two key phenomena in our pilot-scale tests. The first is the ability of flue gas humidification to increase ash cohesivity through the creation of liquid bridges between particles collected in a fabric filter. Increasing cohesivity through the development of liquid bridges was demonstrated in our laboratory measurements of tensile strength and uncompacted bulk porosity, and in filtration studies performed for DOE/PETC under an earlier contract. With the range of coals that will be fired in Southern Research Institute`s Coal Combustion Facility (CCF), filtration tests should verify how different fly ashes react to water conditioning in actual flue gas environments. The CCF provides a valuable test location for our studies. The second phenomenon we plan to study is the electrostatic reentrainment of previously collected ash particles in an ESP. We have prepared a small ESP for use in our pilot-scale tests. Our laboratory studies have shown the effects that relative humidity can have on the forces that hold the collected ash on the grounded …

Lithological and rheological constraints on fault rupture scenarios for ground motion hazard prediction (open access)

Lithological and rheological constraints on fault rupture scenarios for ground motion hazard prediction

This paper tests an approach to predict the range of ground motion hazard at specific sites generated by earthquakes on specific faults. The approach is based upon structural, lithological and rheological descriptions of the fault zones, development of fault rupture scenarios, and computation of synthetic seismograms using empirical Green`s functions. Faults are placed within a regional geomechanical model. The approach is based upon three hypothesis: (1) An exact solution of the representation relation that utilizes empirical Green`s functions enables very accurate computation of ground motions generated by a given rupture; (2) a general description of the rupture is sufficient; and (3) the structural, lithological and Theological characteristics of a fault can be used to constrain, in advance, possible future rupture histories. Ground motion hazard here refers to three-component, full wave train descriptions of displacement, velocity, and acceleration over the frequency band 0.01 to 25 Hz. Corollaries to these hypotheses are that the range of possible fault rupture histories is narrow enough to functionally constrain the range of strong ground motion predictions, and that a discreet set of rupture histories is sufficient to span the infinite combinations possible from a given range of rupture parameters.

Novel carbon-ion fuel cells. First quarter 1995 technical progress report

Research continued on task 2, the measurements on carbides with the fluorite structure. There are twelve known carbides of the fluorite structure with transition temperatures from 350-1450 C. Small quantities of these carbides in powder form will be purchased when commercially available. Pellets pressed from powder within an inert atmosphere will be made, CVI treated, and tested as described in Task No. 1. Pure carbides will be tested first, followed by carbides doped with impurities of different electrical valences whose atomic radii are favorable for solubility in the carbide lattice structure. Dopants will be introduced either during the chemical formation of the carbide, by mix and sinter diffusion, or by high energy ion bombardment of the powder prior to pelletization. The approximate time period for completion of Task No. 2 is twelve months. Investigations have been hampered by equipment failures. Progress is described.

Enhancing the use of coals by gas reburning-sorbent injection. Quarterly report No. 26, January 1--March 31, 1994

The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}), on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, has been stopped because of funding limitations. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and 50 percent in SO{sub x}, emissions, by a combination of two developed technologies, gas reburning (GR) and sorbent injection (SI). With GR, about 80-85 percent of the coal fuel is fired in the primary combustion zone. The balance of the fuel is added downstream as natural gas to create a slightly fuel rich environment in which NO{sub x} is converted to N{sub 2}. The combustion process is completed by overfire air addition. SO{sub x} emissions are reduced by injecting dry sorbents (usually calcium based) into the upper furnace. The sorbents trap SO{sub x} as solid sulfates that are collected in the particulate control device. This project is conducted in three phases at each site: (1) Design and Permitting, (2) Construction and Startup, …

Evaluation of gas-reburning and low NO{sub x} burners on a wall fired boiler. Technical progress report No. 14, January 1, 1994--March 31, 1994

Clean Coal Technology (CCT) implies the use of coal in an environmentally acceptable manner. Coal combustion results in the emission of oxides of nitrogen (NO{sub x}), which are precursors of both acid rain and ozone formation. The primary objective of this CCT project is to evaluate the use of Gas Reburning and Low NO{sub x} Burners (GR-LNB) for NO{sub x} emission control from a wall fired boiler. It is anticipated that, if the demonstration is successful, the GR-LNB technology could become commercialized during the 1990`s and will be capable of (1) achieving significant reduction in the emissions of nitrogen oxides and sulfur dioxide (another acid rain precursor) from existing facilities to minimize environmental impacts such as transboundary and interstate pollution and/or (2) providing for future energy needs in an environmentally acceptable manner. Phase III of the project was approved and commenced on April 15, 1992. Phase III activities during this reporting period involved the continuation of long term testing and the extension of the program through 6-30-95. Additional funds were also allocated and changes in the workscope of Phase III were made to include Gas Reburning System Enhancements.

Global Basins Research Network will perform a field demonstration of their ``Dynamic Enhanced Recovery Technology`` to test the concept that the growth faults in EI-330 field are conduits through which producing reservoirs are charged and that enhanced production can be developed by producing directly from the fault zone. The site, operated by Penzoil, is located in 250 feet of water the productive depth intervals include 4000 to 9000 feet. Previous work, which incorporated pressure, temperature, fluid flow, heat flow, seismic, production, and well log data, indicated active fluid flow along fault zones. The field demonstration will be accomplished by drilling and production test of growth fault systems associated with the EI-330 field. The project utilizes advanced 3-D seismic analysis, geochemical studies, structural and stratigraphic reservoir characterization, reservoir simulation, and compact visualization systems. The quarterly progress reports contains accomplishments to date for the following tasks: Management start-up; database management; field and demonstration equipment; reservoir characterization, modeling; geochemistry; and data integration.
