Infrared Spectra of the Noble Gases

August 1, 2002
Author(s)
Craig J. Sansonetti, M M. Blackwell, Edward B. Saloman
The Atomic Spectroscopy Data Center of the National Institute of Standards and Technology (NIST) is currently compiling spectra and energy levels of the noble gases. A review of the literature has shown that there is no comprehensive experimental

MALDI MS Characterization of Covalent Cationized Polyethylene

August 1, 2002
Author(s)
Sheng Lin-Gibson, D L. Brunner, David L. VanderHart, Barry J. Bauer, B M. Fanconi, Kathleen M. Flynn, William E. Wallace
Polyolefins, saturated hydrocarbon polymers such as polyethylene (PE) and polypropylene, are, by production volume, the most widely used of all A new method for the mass spectrometry of saturated polyolefins whereby an organic cation is covalently bonded

Measured cross sections and ion energies for a CHF 3 discharge.

August 1, 2002
Author(s)
B. Peko, R. Champion, MVVS. Rao, James K. Olthoff
Trifluoromenthane (CHF 3) is used in semiconductor plasma processing chambers to achieve high etch selectivity of an oxide layer over a silicon substrate. Such surface etching is governed by the ion and molecule fluxes near the surface, the concentrations

MeasuringThe Modulus of Polymer Films by Strain-Induced Buckling Instabilities

August 1, 2002
Author(s)
Christopher M. Stafford, C Harrison, Alamgir Karim, Eric J. Amis
We present a high-throughput technique for measuring the Young s modulus of thin polymer films. This technique exploits a strain-induced buckling instability observed in films supported on elastomeric substrates. By employing a combinatorial polymer film

Metal Detector Studies: Research Materials

August 1, 2002
Author(s)
James R. Baker-Jarvis, Raian K. Kaiser, Michael D. Janezic, Nicholas Paulter, Ken L. Stricklett
The purpose of the work described in this report is to develop and characterize materials that mimic the electromagnetic characteristics of the human body. The materials will be used to simulate the relevant electromagnetic properties of the human body

Modified Allard Method for Effective Intensity of Flashing Lights

August 1, 2002
Author(s)
Yoshihiro Ohno, D Couzin
For the measurement of effective intensity of flashing lights, the Blondel-Rey, Blondel-Rev-Douglas, Form Factor, and Allard methods are adopted in various applications. These methods produce significantly different results depending on the pulse waveforms

NIST CFTT: Testing Disk Imaging Tools

August 1, 2002
Author(s)
James R. Lyle
There is a critical need in the law enforcement community to ensure the reliability of computer forensic tools. A capability is required to ensure that forensic software tools consistently produce accurate and objective test results. The goal of the

Numerical Modeling of an Integrating Sphere Radiation Source

August 1, 2002
Author(s)
A Prokhorov, Leonard Hanssen
Integrating spheres are often used as calibration sources providing uniform radiance within solid angle and/or uniform irradiance at a distance. The best performance in such a system can be achieved if one is able to evaluate as well as predict important

Optimizing the Covalent Cationization Method for the Mass Spectrometry of Polyolefins

August 1, 2002
Author(s)
Sheng Lin-Gibson, L Brunner, David L. VanderHart, Barry J. Bauer, B M. Fanconi, Charles M. Guttman, William E. Wallace
Previously a new method was introduced for the mass spectrometry of polyolefins whereby an organic cation is covalently bonded to the polymer to produce the necessary ionization for the creation of intact gas?phase macromolecules by matrix-assisted laser

Phase Behavior in Polyolefin Blend

August 1, 2002
Author(s)
G Matsuba, K Shimizu, Haonan Wang, Z G. Wang, Charles C. Han
The phase behavior in copolymer blend of PEH(60)PEB(40) blend has been studied by phase contrast optical microscopy within the two phase region. In single quench, the interconnected biocontinuous structure was observed in molten state. The interconnected

Photoassociation in a Bose-Einstein Condensate

August 1, 2002
Author(s)
Paul D. Lett
Two colliding atoms can absorb a photon and be photoassociated into an excited, diatomic molecule, NIST researchers investigated the fundamental rate at which this process can take place in a Bose-Einstein condensate (BEC) and demonstrated that simple

Polymer Science at the NIST Combinatorial Methods Center

August 1, 2002
Author(s)
Cher H. Davis, Kathryn L. Beers, Aaron M. Forster, Christopher M. Stafford, A P. Smith, C Harrison, Weiping Zhang, Alamgir Karim, Eric J. Amis
The measurements, standards, and test methods developed by NIST, in partnership with other organizations, often help unlock the potential of new discoveries and budding technologies. Combinatorial methods are a textbook example. These emerging tools can

Quadruple Suspension Design for Advanced LIGO

August 1, 2002
Author(s)
N A. Robertson, G Cagnoli, D R M Crooks, E Elliffe, J E. Faller, P Fritschel, S Gossler, A Grant, A Heptonstall, Jon T. Hougen, H Luck, R Mittleman, R-Loyd` Perreur-Loyd, M V. Plissi, S Rowan, D H. Shoemaker, P Sneddon, K A. Strain, C I. Torrie, H Ward, P Willems
In this paper, we describe the conceptual design for the suspension system for the test masses for Advanced LIGO, the planned upgrade to LIGO, the US Laser Interferometric Gravitational-wave Observatory. The design is based on the triple pendulum design
