A Pulse Measurement Intercomparison

October 1, 1998
Author(s)
T. M. Souders, J R. Andrews, A. Caravone, J. P. Deyst, C. Duff, S. Naboicheck
A pulse measurement intercomparison, organized by (NIST) and conducted by the authors in their respective labs, is described. The purpose was to assess the state of the art for time-domain pulse-waveform measurements in the nanosecond regime, and to find

Thermodynamic Properties of Air at Pressures to 2000 MPa

August 1, 1998
Author(s)
William M. Haynes, Eric W. Lemmon, Daniel G. Friend, R Jacobsen
A new formulation for the thermodynamic properties of standard dry air at pressures to 2000 MPa has been developed. This formulation, which can be used at temperatures from the freezing liquid line to 2000 K, is based on comprehensive experimental

… two components with periods of 2.48plus or minus}0.05 layers (0.506plus or minus}0.010 nm) and 8.6plus or …

Scanning Electron Microscopy With Polarization Analysis (SEMPA)

January 1, 1990
Author(s)
M Scheinfein, John Unguris, Michael H. Kelley, Daniel T. Pierce, Robert Celotta
This was an extended abstract prepared for inclusion in the Microscopy & Microanalysis '99 Proceedings. It is a summary of Observation of Antiparallel Magnetic Order in Weakly Coupled Co/Cu Multilayers, which was published in Physical Review Letters, Vol

The Rich Transcription 2005 Spring Meeting Recognition Evaluation

Author(s)
Jonathan G. Fiscus, Nicolas Radde, John S. Garofolo, A N. Le, Jerome G. Ajot, Christophe Laprun
This paper presents the design and results of the Rich Transcription Spring 2005 (RT-05S) Meeting Recognition Evaluation. This evaluation is the third in a series of community-wide evaluations of language technologies in the meeting domain. For 2005, four

NIST-F3, a cesium fountain frequency reference

January 24, 2023
Author(s)
Gregory Hoth, Alexander Radnaev, Peter Mitchell, Jeffrey Sherman, Vladislav Gerginov
A cesium fountain frequency reference known as NIST-F3 is under development at the National Institute of Standards and Technology (NIST). The fountain is intended to provide input for the NIST timescale and assist with evaluation of NIST's primary and

Magnetic Characterization of Electrodeposited Pt1-xNix Alloy Films: Influence of Deposition Potential and the Presence of Boric Acid

September 21, 2022
Author(s)
Eric Rus, Eduardo De Lima Correa, Evan Groopman, Todd Williamson, Hussein Hijazi, Leila Kasaei, Leonard Feldman, Cindi L. Dennis, Thomas P. Moffat
Pt1-xNix (x = 0.25 to 0.92) thin films were examined for possible application as temperature sensing magnetic reporters. The alloys were prepared by charge-limited potentiostatic electrodeposition from aqueous chloride-based solutions in the presence and

Effects of Solution pH and Surface Chemistry on the Post-Deposition Growth of Chemical Bath Deposited PbSe Nanocrystalline Films

October 12, 2021
Author(s)
Shaibai K. Sarkar, Shifi Kababya, Shimon Vega, Hagal Cohen, Joseph Woicik, A I. Frenkel, Gary Hodes
Chemical bath deposited PbSe films were subjected to post-deposition treatment with aqueous (typically 0.25 - 0.5 M) KOH. For films deposited using a citrate complex, this treatment resulted in dissolution of surface lead oxides (seen from XPS and EXAFS

Neutron Imaging of Laser Melted SS316 Test Objects with Spatially Resolved Small Angle Neutron Scattering

April 21, 2021
Author(s)
Daniel S. Hussey, Adam J. Brooks, Caroline G. Lowery, Gerald L. Knapp, Bridget E. Cadigan, Shengmin Guo, Leslie G. Butler
A novel neutron far field interferometer is explored for sub-micron porosity detection in laser sintered SS316 test objects. The results shown are images and volumes of the first quantitative neutron dark-field tomography at various autocorrelation lengths

Structural Performance of Nuclear Power Plant Concrete Structures Affected by Alkali-Silica Reaction (ASR) - Task 1: Assessing In-Situ Mechanical Properties of ASR-Affected Concrete

February 8, 2021
Author(s)
Fahim H. Sadek, Travis E. Thonstad, Sorin Marcu, Jonathan Weigand, timothy J. barrett, Hai S. Lew, Long Phan, Adam L. Pintar
This report describes the results of Task 1 of a five-task comprehensive research program being conducted at the National Institute of Standards and Technology (NIST) under the sponsorship of the U.S. Nuclear Regulatory Commission (NRC). The overall study

Axial force radiometer for primary standard laser power measurements using photon momentum

January 11, 2021
Author(s)
Paul Williams, Kyle Rogers, Joshua A. Hadler, Alexandra Artusio-Glimpse, John Lehman
We have fully demonstrated operation of a new photon momentum radiometer for measuring laser power levels above 1 kW by use of radiation pressure. The "axial" design allows the input and output laser beams to remain collinear and the force sensing can be
