NIST Realization of the ITS-90 Gallium Fixed Point

Author(s)
Gregory F. Strouse
As defined by the International Temperature Scale of 1990 (ITS-90), the gallium melting-point cell (29.7646 C) is used in the calibration of standard platinum

Stabilization of SPRTs for ITS-90 Calibrations

Author(s)
Dennis B. Minor, Gregory F. Strouse
At the National Institute of Standards and Technology (NIST), the ITS-90 calibration of standard platinum resistance thermometers (SPRTs) is performed in the

Stress Testing a Supply Chain Using Simulation

Author(s)
Sanjay Jain, Swee K. Leong
Simulation provides the capability to evaluate performance of a system operating under current or proposed configura-tions, policies and procedures. It is very

Spectroscopy of a single Al+ ion via coupling to Be+

Author(s)
Till P. Rosenband, Piet Schmidt, Jeroen Koelemeij, Wayne M. Itano, Yohei Kobayashi, Tara M. Fortier, Scott A. Diddams, James C. Bergquist, David J. Wineland
We perform precision spectroscopy on 27Al + with the aid of a 9Be + ion. Using sympathetic cooling and quantum state transfer, we efficiently interrogate the 1S

Optical Microwave Frequency Stability: Some Constraints

Author(s)
Leo W. Hollberg, Scott A. Diddams, A Bartels, John J. McFerran, Eugene N. Ivanov, G Wilpers, Christopher W. Oates
Optical frequency references achieve the best frequency stability of any oscillators by taking advantage of high Q = υ 0/{Δ}υ optical resonances. These systems

Fiber Laser Frequency Combs and their Control

Author(s)
Nathan R. Newbury, Brian Washburn, William C. Swann, Jeffrey W. Nicholson, K Feder, Paul S. Westbrook
Fiber laser-based frequency combs can provide a comb of well-defined spectral lines across the near-infrared, including the telecommunication. We discuss these

mLab: A Mobile Ad Hoc Network Test Bed

Author(s)
Tom T. Karygiannis, Emmanouil Antonakakis
Over the last few years, research in the area of mobile ad hoc networks (MANETs) has focused on routing protocol performance improvements, security enhancements

Toward an Improved Color Rendering Metric

Author(s)
Wendy L. Davis, Yoshihiro Ohno
Several aspects of the Color Rendering Index (CRI) are flawed, limiting its usefulness in assessing the color rendering capabilities of LEDs for general
