A pyroelectric detector-based method for low uncertainty spectral irradiance and radiance responsivity calibrations in the infrared using tunable lasers

April 4, 2022
Author(s)
Brian Alberding, John Woodward, Ping-Shine Shaw, Leonard Hanssen, Catherine Cooksey, Joseph P. Rice
The standard uncertainty of detector-based radiance and irradiance responsivity calibrations in the short-wave infrared (SWIR) traditionally has been limited to around 1 % or higher by the low spatial uniformity of detectors used to transfer the scale from

Quantum-enhanced sensing of displacements and electric fields with large trapped-ion crystals

August 6, 2021
Author(s)
Kevin Gilmore, Matthew Affolter, Judith Jordan, Diego Barberena, Robert Lewis-Swan, Ana Maria Rey, John J. Bollinger
Developing the isolation and control of ultracold atomic systems to the level of single quanta has led to significant advances in quantum sensing, yet demonstrating a quantum advantage in real world applications by harnessing entanglement remains a core

Thermal Boundary Layers in Critical Flow Venturis

July 30, 2021
Author(s)
John D. Wright, Aaron Johnson, Michael R. Moldover, Woong Kang, Liang Zhang, Bodo Mickan
… < 10 mm) critical flow venturis (CFVs) as transfer standards for gas flow by measuring and explaining how their …

Facility for calibrating anemometers as a function of air velocity vector and turbulence

July 19, 2021
Author(s)
Iosif Isaakovich Shinder, Michael R. Moldover, James Filla, Aaron Johnson, Vladimir B. Khromchenko
NIST calibrates anemometers as a function of airspeed vector and turbulence intensity (Tu). The vector capability (sometimes called '3D') is particularly important for calibrating multi-hole differential-pressure probes that are often used to quantify

Far-field interference of a neutron white beam and the applications to noninvasive phase-contrast imaging

April 21, 2021
Author(s)
Michael G. Huber, Daniel S. Hussey, Muhammad D. Arif, David L. Jacobson, Jacob LaManna, Wakana Ueno, Han Wen, Dmitry Pushin, Dusan Sarenac, David Cory, Houxun Miao, Takenao Shinohara, Joseph Parker
The phenomenon of interference plays a crucial role in the field of precision measurement science. Waveparticle duality has expanded the well-known interference effects of electromagnetic waves to massive particles. The majority of the wave-particle

Elastic-plastic properties of mesoscale electrodeposited LIGA nickel alloy films: microscopy and mechanics

November 22, 2020
Author(s)
Li-Anne Liew, David T. Read, May Martin, Frank W. DelRio, Peter E. Bradley, Nicholas Barbosa, Todd R. Christenson, John T. Geaney
The elastic-plastic properties of mesoscale electrodeposited LIGA Ni alloy specimens are investigated as a function of specimen size, strain rate, and material composition. Two material compositions are studied: a high-strength fine-grained Ni-Fe alloy and
