Electro-Optic Kerr Effect in Spun High-Birefringent Fiber Current Sensors

October 1, 2000
Author(s)
Allen Rose, P. G. Polynkin, J. Blake
We have measured the influence of the electro-optic (EO) Kerr effect on the response of a spun high-birefringence (hi-bi) fiber current sensor in a simulated Gas Insulated System (GIS) environment. We show that the EO Kerr effect distorts the response of

Electron Collision Data for Plasma-Processing Gases

October 1, 2000
Author(s)
Loucas G. Christophorou, James K. Olthoff
Low-temperature plasma applications require detailed understanding of the physical and chemical processes occurring in the plasmas themselves. For instance, as the push for smaller feature sizes and higher quality devices in the semiconductor industry has

Electron Interactions with Excited Atoms and Molecules

October 1, 2000
Author(s)
Loucas G. Christophorou, James K. Olthoff
Elastic, inelastic, and superelastic scattering of electrons by and electron-impact ionization of excited atoms are reviewed and discussed and the role of the electric dipole polarizabilty in the interaction of slow electrons with excited atoms is

Equation of State for Star Polymers in Good Solvents

October 1, 2000
Author(s)
C S. Patrickios, L L. Lue
We develop a free-energy model for star polymers in good solvents that accurately describes concentrated polymer solutions and displays the correct universal scaling behavior, in the limit of infinite molecular weigth, for dilute and semidilute polymer

Evaluation of an EMC Compliance Chamber Using an Ultrawideband Measurement System

October 1, 2000
Author(s)
Robert T. Johnk, David R. Novotny, Claude Weil, Marlene Taylor, T. J. O'Hara
This paper summarizes a joint NIST-Industry measurement effort. The purpose of this effort was to use a NIST-developed altrawide band measurement system to assess the performance imporvement of ferrite tile anechoic chamber after a partial retrofit

Experimental and Thermodynamic Assessment of Sn-Ag-Cu Solder Alloys

October 1, 2000
Author(s)
Kil-Won Moon, William J. Boettinger, Ursula R. Kattner, Frank S. Biancaniello, C A. Handwerker
Sn-rich alloys in the Sn-Ag-Cu system are being studied for their potential as Pb-free solders. Thus, the location of the ternary eutectic involving L, (Sn), Ag 3)Sn and Cu( 6)Sn( 5) phases is of critical interest. Phase diagram data in the Sn-rich corner

Fair Selection of Jury Panels From Jury Pools

October 1, 2000
Author(s)
J L. Blue
A standard problem of courts at all levels is the selection of a panel of potential jurors from a jury pool, which is a list of people who are eligible to serve as jurors. The problem is to select N people out of the M possible people in a fair way. One

Field Demonstration of Laser Scanning for Excavation Measurement

October 1, 2000
Author(s)
Geraldine S. Cheok, Robert R. Lipman, Christoph J. Witzgall, Javier Bernal, William C. Stone
The use of a scanning laser to measure terrain changes due to excavation at a construction site is described. The objective at this phase of the project is to develop the tools necessary to measure terrain changes in real-time. This paper focuses on

First Observation of the n 17 - n 4 Difference Bands of Diborane 10 B 2 H 6 and 11 B 2 H 6

October 1, 2000
Author(s)
J.- M. Flaud, Walter J. Lafferty, H Berger, G Pawelke, J L. Domenech, D Bermejo
An analysis of the Ņ 17 - Ņ 4 difference bands of two isotopic species, 10B 2H 6 and 11B 2H 6, of diborane has been carried out using infrared spectra recorded with a resolution of ca. 0.003 cm -1. In addition, the Ņ 17 band of 10B 2H ^ has been recorded

Future of Fire Investigation

October 1, 2000
Author(s)
Daniel M. Madrzykowski
As the legal climate for arson and fire investigations becomes more demanding, their need for a rigorous scientific foundation is growing. Fortunately, federal research efforts are already starting to close the gap.

Halocarbons 1: Methane Derivatives

October 1, 2000
Author(s)
Arno D. Laesecke
This poster (47 in x 30 in) shows ab initio computed structures of the chlorine and/or fluorine derivatives of methane. Some of these compounds are working fluids (ozone depleting and alternative) in refrigeration and air conditioning equipment. Others are

Interfacial Response of a Fluorescent Dye Grafted to Glass

October 1, 2000
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, J H. VanZanten, Joy Dunkers, Richard~undefined~undefined~undefined~undefined~undefined Parnas
The Quality of the fiber/resin interphase region is critical to the final mechanical properties of a composite. By grafting a fluorescent dye to a glass microscope cover slip, a model interphase region can be directly studied. A blue shift and increase in

ITL Technical Accomplishments 2000

October 1, 2000
Author(s)
Elizabeth B. Lennon, K K. Simon, M Helfer
The ITL Technical Accomplishments 2000 report presents the achievements and highlights of NIST's Information Technology Laboratory (ITL) during FY 2000. Technical projects in eight divisions are described, followed by industry interactions, international
