Algorithm for Rapid Tomography of Gas Concentrations

Description: We present a new computed tomography method, the low third derivative (LTD) method, that is particularly suited for reconstructing the spatial distribution of gas concentrations from path-integral data for a small number of optical paths. The method finds a spatial distribution of gas concentrations that (1) has path integrals that agree with measured path integrals, and (2) has a low third spatial derivative in each direction, at every point. The trade-off between (1) and (2) is controlled by … more

Small Neutrino Masses from Supersymmetry Breaking

Description: An alternative to the conventional see-saw mechanism is proposed to explain the origin of small neutrino masses in supersymmetric theories. The masses and couplings of the right-handed neutrino field are suppressed by supersymmetry breaking, in a way similar to the suppression of the Higgs doublet mass, $\mu$. New mechanisms for light Majorana, Dirac and sterile neutrinos arise, depending on the degree of suppression. Superpartner phenomenology is greatly altered by the presence of weak scale r… more

Entanglement and Quantum Computation: An Overview

Description: This report presents a selective compilation of basic facts from the fields of particle entanglement and quantum information processing prepared for those non-experts in these fields that may have interest in an area of physics showing counterintuitive, ''spooky'' (Einstein's words) behavior. In fact, quantum information processing could, in the near future, provide a new technology to sustain the benefits to the U.S. economy due to advanced computer technology.

Waste Transfer Leaks Control Decision Record

Description: Control decision meetings for Waste Transfer Leaks were held on April 24,25,26, and 27, 2000. The agenda for the control decision meetings is included in Appendix A, and attendee lists are included in Appendix B. The purpose of the control decision meetings was to review and revise previously selected controls for the prevention or mitigation of waste transfer leak accidents. Re-evaluation of the controls is warranted due to revisions in the hazard and accident analysis for these Tank Farm even… more

Lawrence Livermore National Laboratory Quality Assurance Project Plan for National Emission Standards for Hazardous Air Pollutants (NESHAPs), Subpart H

Description: As a Department of Energy (DOE) Facility whose operations involve the use of radionuclides, Lawrence Livermore National Laboratory (LLNL) is subject to the requirements of 40 CFR 61, the National Emission Standards for Hazardous Air Pollutants (NESHAPs). Subpart H of this Regulation establishes standards for exposure of the public to radionuclides (other than radon) released from DOE Facilities (Federal Register, 1989). These regulations limit the emission of radionuclides to ambient air from D… more

A superconducting quadrupole magnet array for a heavy ion fusion driver

Description: A multi-channel quadrupole array has been proposed to increase beam intensity and reduce space charge effects in a Heavy Ion Fusion Driver. A single array unit composed of several quadrupole magnets, each with its own beam line, will be placed within a ferromagnetic accelerating core whose cost is directly affected by the array size. A large number of focusing arrays will be needed along the accelerating path. The use of a superconducting quadrupole magnet array will increase the field and redu… more

Syria after Hafiz al-Asad

Description: This report the country of Syria following the rule of Hafiz al-Asad. Dr. Bashar al-Asad seems poised to succeed his father, the late President Hafiz al-Asad, following the latter's death from a heart attack on June 10, 2000; however, Bashar is untested and may face challenges from other leading figures or dissidents. No major changes in Syria's position on peace talks with Israel or relations with the United States seem likely while the successor regime consolidates its control.

Ion storage techniques and time-of-flight mass spectrometry in physical forensic science

Description: Effective investigative analysis requires proper selection of sample-collection procedures, preservation, and analysis methods. To achieve these objectives it is essential to tailor the collection and analysis methods to the application requirements, which are constrained by different parameters such as analysis time, sample concentration, matrix interferences, and analyte stability (e.g., surface activity (''stickiness'') and chemical reactivity). In addition, method optimization must be accom… more

Clear Sky Identification Using Data From Remote Sensing Systems at ARM's Southern Great Plains Site

Description: Clouds profoundly affect our weather and climate due, in large part, to their interactions with radiation. Unfortunately, our understanding of these interactions is, at best, incomplete, making it difficult to improve the treatment of atmospheric radiation in climate models. The improved treatment of clouds and radiation, and a better understanding of their interaction, in climate models is one of the Department of Energy's Atmospheric Radiation Measurement (ARM) Program's major goals. To learn… more

Electronic Commerce: An Introduction

Description: Electronic commercial transactions over the Internet, or “e-commerce,” have grown so fast over the last five years that many experts continue to underestimate its growth and development. Whether retail business-to-customer or business-to-business transactions, e-commerce shows no signs of slowing down. In turn, policymakers both in the United States and abroad are likely to face increasingly complex issues of security, privacy, taxation, infrastructure development and other issues in 2000 a… more

Photon-Assisted Transmission through a Double-Barrier Structure

Description: The authors study multi-photon-assisted transmission of electrons through single-step, single-barrier and double-barrier potential-energy structures as a function of the photon energy and the temperature. Sharp resonances in the spectra of the tunneling current through double-barrier structures are relevant to infra-red detectors.

Retention and Switching Kinetics of Protonated Gate Field Effect Transistors

Description: The switching and memory retention time has been measured in 50 {micro}m gatelength pseudo-non-volatile memory MOSFETs containing, protonated 40 nm gate oxides. Times of the order of 3.3 seconds are observed for fields of 3 MV cm{sup {minus}1}. The retention time with protons placed either at the gate oxide/substrate or gate oxide/gate electrode interfaces is found to better than 96% after 5,000 seconds. Measurement of the time dependence of the source-drain current during switching provides cl… more
