Measuring residual resistivity ratio of high-purity Nb

Author(s)
Loren F. Goodrich, Theodore C. Stauffer, Jolene Splett, Dominic F. Vecchia
We compared methods of measuring the residual resistivity ratio (RRR) of high-purity Nb using transport current. Our experimental study is intended to answer

Quantum information processing with trapped ions

Author(s)
Murray D. Barrett, Tobias Schaetz, J Chiaverini, Dietrich Leibfried, Joseph W. Britton, Wayne M. Itano, John D. Jost, Emanuel Knill, C. Langer, R Ozeri, David J. Wineland
We report experiments on the creation and manipulation ofmulti-particle entangled states of trapped atomic ions. The experiments reported here, quantum dense

Improving CNC Machining Accuracy Through Thermal Model-Based Control

Author(s)
John L. Michaloski, Frederick M. Proctor, Johannes A. Soons, R King, W Bakula, H Dominguez, N Frampton
The United States Army has a requirement to machine munitions to strict tolerances so that the munitions will launch properly and the explosives will detonate

Fire Performance of Partition Assemblies

Author(s)
Samuel L. Manzello, Richard G. Gann, S R. Kukuck, Kuldeep R. Prasad, Walter W. Jones
For nearly a century, the cornerstone of fire safety in buildings has been the ability to confine a fire for a time sufficient for people to reach safety and

Modeling Warm-Up Drift in Commercial Harmonic Phase Standards

Author(s)
Jeffrey Jargon, Jolene Splett, Dominic F. Vecchia, Donald C. DeGroot
We develop an empirical model for the warm-up drift of harmonic phase standards that are used to calibrate the phase distortion of nonlinear vector nrtworks

Refractometry Using a Helium Standard

Author(s)
Jack A. Stone Jr., Alois Stejskal
The refractive index of helium at atmospheric pressure can be calculated from first principles with a very low uncertainty, on the order of 10^-10. Furthermore
