Calculation of magnetic forces and torques on the Kibble coil
Stephan Schlamminger, Lorenz Keck, Frank Seifert +3
Analytically the forces and torques on a coil in a field of magnetic flux density can be calculated one of two ways. The line integral can be conducted along the coil's wire, summi…
Resolution of the paradox of the diamagnetic effect on the Kibble coil
Shisong Li, Stephan Schlamminger, Rafael Marangoni +6
Employing very simple electro-mechanical principles known from classical physics, the Kibble balance establishes a very precise and absolute link between quantum electrical standar…
Magnet system for the Quantum Electro-Mechanical Metrology Suite
Rafael R. Marangoni, Darine Haddad, Frank Seifert +3
The design of the permanent magnet system for the new Quantum Electro-Mechanical Metrology Suite (QEMMS) is described. The QEMMS, developed at the National Institute of Standards a…
The Performance of the KIBB-g1 Tabletop Kibble Balance at NIST
Leon Chao, Frank Seifert, Darine Haddad +3
A tabletop-sized Kibble balance (KIBB-g1) designed to directly realize mass at the gram-level range with uncertainties on the order of parts in 10 has been developed at the Nat…
Measurement of the Planck constant at the National Institute of Standards and Technology from 2015 to 2017
D. Haddad, F. Seifert, L. S. Chao +5
Researchers at the National Institute of Standards and Technology(NIST) have measured the value of the Planck constant to be Js (relati…
First measurements of the flux integral with the NIST-4 watt balance
D. Haddad, F. Seifert, L. S. Chao +5
In early 2014, construction of a new watt balance, named NIST-4, has started at the National Institute of Standards and Technology (NIST). In a watt balance, the gravitational forc…
A summary of the Planck constant measurements using a watt balance with a superconducting solenoid at NIST
S. Schlamminger, R. L. Steiner, D. Haddad +6
Researchers at the National Institute of Standards and Technology have been using a watt balance, NIST-3, to measure the Planck constant for over ten years. Two recently publis…
A determination of the local acceleration of gravity for the NIST-4 watt balance
E. J. Leaman, D. Haddad, F. Seifert +5
A new watt balance is being constructed at the National Institute of Standards and Technology (NIST) in preparation for the redefinition of the International System of Units and th…
A LEGO Watt Balance: An apparatus to determine a mass based on the new SI
L. S. Chao, S. Schlamminger, D. B. Newell +6
A global effort to redefine our International System of Units (SI) is underway and the change to the new system is expected to occur in 2018. Within the newly redefined SI, the pre…
Construction, Measurement, Shimming, and Performance of the NIST-4 Magnet System
Frank Seifert, Alireza Panna, Shisong Li +7
The magnet system is one of the key elements of a watt balance. For the new watt balance currently under construction at the National Institute of Standards and Technology, a perma…
