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 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…
