Charged particle and neutron backgrounds in an e-e- interaction region at the NLC
We compare the detector background situation in an e{sup -} e{sup -} interaction region at the NLC with previous studies done of the NLC e{sup +} e{sup -} interaction region. We note from previous studies that the dominant source of detector backgrounds are the beamstrahlung pairs. Since these scale with luminosity, the reduction in luminosity in e{sup -} e{sup -} collisions leads to a reduction in detector backgrounds compared to the e{sup +} e{sup -} situation.

Confocal Imaging of Biological Tissues Using Second Harmonic Generation
A confocal microscopy imaging system was devised to selectively detect Second harmonic signals generated by biological tissues. Several types of biological tissues were examined using this imaging system, including human teeth, bovine blood vessels, and chicken skin. All these tissues generated strong second harmonic signals. There is considerable evidence that the source of these signals in tissue is collagen. Collagen, the predominant component of most tissues, is known to have second order nonlinear susceptibility. This technique may have diagnostic usefulness in pathophysiological conditions characterized by changes in collagen structure including malignant transformation of nevi, progression of diabetic complications, and abnormalities in wound healing.

Cost reduction and manufacture of the SunSine{reg_sign} AC module: Phase I Annual Report : 21 April 1998 -- 31 October 1999
This report summarizes the progress made by Ascension Technology in Phase 1 of the cost reduction and manufacturing improvements of the SunSine{reg_sign} AC Module. This work, conducted under NREL subcontract, is a two-phase effort consisting of investigations into improving inverter packaging, soft switching, circuit optimization, design for manufacturing, manufacturing processes, and pilot production manufacturing. The objective of this subcontract is to significantly reduce the cost of the SunSine{reg_sign} inverter, enhance its performance, and streamline and expand the manufacturing process. During Phase 1, the soft-switching topology was designed, then refined to meet stringent cost and performance goals. This design resulted in improved performance, smaller overall footprint, and reduced costs. The aluminum inverter housing was redesigned, and the decision was made to conformal coat the circuit boards, which was verified through the HAST (Highly Accelerated Stress Testing) method. Potential international markets were identified, and the inverter is designed to be easily modified to meet the requirements of other countries. Significant cost reduction and performance improvements have been achieved in Phase I, and accomplishments during Phase I include: (1) SunSine{reg_sign} AC Module costs have been reduced enough to be able to reduce the suggested list price; (2) successful implementation of soft-switching; (3) power …

The DARHT-II-DC Final Focus Solenoid
The baseline DARHT2 external beam uses a pulsed solenoid final focus lens. The design of this lens was presented at TOS2 and has been considered as the final focus lens in all of the Livermore beamlines for DARHT2. In this note, we consider a new alternative DC final focus solenoid. A crude comparison between the parameters of these two designs is given in table 1. The small spot size required by the radiography and the small drift distance available between the last magnetic focusing element and the final focus solenoid imposed by the close proximity between the DARHT 2 building and the DARHT 1 axis, implies a short focal length solenoid. This in turn requires that the final focus solenoid mount inside the re-entrant cavity of the containment vessel in order to accommodate the 0.9 meter conjugate: figure 1. The ID of this cavity is 13.88 inches (35.25 cm).

Development of a fully-integrated PV system for residential applications: Phase I annual technical report: February 27, 1998 -- August 31, 1999
This report describes Utility Power Group's (UPG's) technical progress for Phase 1 of a two-phase effort to focus on the design, assembly, and testing of a fully-integrated residential PV power system, including storage. In the PV Array Task, UPG significantly improved the conventional means and methods required to structurally interface PV modules to the roofs of single-family residential houses and to electrically interconnect these PV modules to a power conversion unit. UPG focused on the design and test of a PV array based on the highly efficient use of materials and labor. Design criteria included cost, structural integrity, electrical safety, reliability, conformance with applicable standards and building and seismic codes, and adaptability to a wide range of roof materials for both existing and retrofit roof applications. In the Power Unit Task, UPG designed and tested a high-efficiency, low-cost, high-reliability prototype power conversion unit that included all materials, components, equipment, and software required to perform all DC-AC/AC-DC power collection, conversion, and control functions between the output of the PV array and the interconnection to the electrical grid service of single-family residences. In the Energy Storage Unit Task, UPG designed and tested a low-cost, modular, self-contained, low-maintenance, all-weather, battery-based Energy Storage Unit …

Engineered Antibodies for Monitoring of Polynuclear Aromatic Hydrocarbons
Polynuclear aromatic hydrocarbons (PAHs) are a large class of structurally similar pollutants. Rapid, inexpensive, and high-throughput methods to identify and monitor PAHs are needed in several DOE focus areas, including human and ecosystem health effects, risk and exposure assessment, decontamination and decommissioning, and remediation. DOE has sponsored and participated in several demonstration projects in which commercial immunoassay kits proved useful and cost-effective for detection of PAHs and other pollutants. The emerging generation of sensors and residue recovery methods will require panels of antibodies with relatively subtle differences in cross-reactivity. This project is based on the premise that genetic engineering should be much more successful than conventional polyclonal and monoclonal antibody methods for developing these antibody panels. One objective of this project has been to define the structural basis and mechanisms by which antibodies bind and cross-react with various PAHs. A second objective has been to use this information to produce recombinant antibodies with improved performance in analytical procedures that DOE can use. A third objective has been development of PAH residue recovery and cleanup methods that will be compatible with immunoassays, and make instrumental analysis faster, more accurate, and less expensive.

Femtosecond Laser Materials Processing
The use of femtosecond lasers allows materials processing of practically any material with extremely high precision and minimal collateral damage. Advantages over conventional laser machining (using pulses longer than a few tens of picoseconds) are realized by depositing the laser energy into the electrons of the material on a time scale short compared to the transfer time of this energy to the bulk of the material, resulting in increased ablation efficiency and negligible shock or thermal stress. The improvement in the morphology by using femtosecond pulses rather than nanosecond pulses has been studied in numerous materials from biologic materials to dielectrics to metals. During the drilling process, we have observed the onset of small channels which drill faster than the surrounding material.

Final report: Accelerated beta decay for disposal of fission fragment wastes
The fundamental theory of the interaction of intense, low-frequency electromagnetic fields with certain radioactive nuclei has been fully formulated. The nuclei are of the type that exists in high-level radioactive wastes that are end products of the production of energy from nuclear fission. The basic physical mechanisms that underlie the coupling of the applied field to the nucleus have been identified. Both the basic theory and numerical predictions that stem from it support the conclusion that high-level radioactive wastes can be disposed of by substantially accelerating the rate of radioactive decay. Some old experiments on the acceleration of this type of radioactivity, with results that were not understood at the time, have been re-examined. Their interpretation is now clear, and the experiments are found to be in agreement with the theory.

High molecular orientation in mono- and tri-layer polydiacetylene films imaged by atomic force microscopy
Atomically flat monolayer and trilayer films of polydiacetylenes have been prepared on mica and silicon using a horizontal deposition technique from a pure water subphase. Langmuir films of 10,12-pentacosadiynoic acid (I) and N-(2-ethanol)-10,12-pentacosadiynamide (II) were compressed to 20 mN/m and subsequently polymerized by UV irradiation at the air-water interface. Blue and red forms of the films were prepared by varying exposure times and incident power. Polymerization to the blue-phase films produced slight contractions in the film of 2 and 5% for the films of II and I, respectively. Longer UV exposures yielded red-phase films with dramatic film contraction of 15 and 32% for II and I, respectively. The horizontal deposition technique provided transfer ratios of unity with minimal film stress or structure modification. Atomic force microscopy images revealed nearly complete coverage of the substrate with atomically flat films. Crystalline domains of up to 100 microns of highly oriented polydiacetylene molecules were observed. The results reported herein provided insight into the roles of molecular packing and chain orientations in converting the monomeric film to the polymerized blue- and red-phases.

HSB 84A pumping test
Two constant discharge, multiple well pumping tests were performed in the Congaree aquifer at the H-Area seepage basins during the weeks of April 30 through May 11. The purpose of the tests was to collect information that might determine the source of groundwater contamination in the Congaree aquifer and to estimate the hydraulic parameters of the aquifer. Transmissivity estimates from data collected in Test One ranged from 1,644 ft{sup 2}/day to 2,253 ft{sup 2}/day with an average of 2,013 ft{sup 2}/day and from 1,812 ft{sup 2}/day to 2,562 ft{sup 2}/day with an average of 2,269 ft{sup 2}/day in Test Two. Some leakage through the confining bed was apparent in the vicinity of observation well HSB 69A. This report includes the data collected, the analyses, results and interpretation of the pumping tests performed at HSB 84A. It should serve as a good baseline for future studies on the subject of contaminant migration in the Congaree aquifer on the Savannah River Site.
