The distribution of the electric current in a watt-balance coil
Carlo Paolo Sasso, Enrico Massa, Giovanni Mana
In the watt balance experiments, separate measurements of the magnetic and electromotive forces in a coil in a magnetic field enable a virtual comparison between mechanical and ele…
Precision measurements of the Planck and Avogadro constants
Horst Bettin, Kenichi Fujii, John Man +3
Precision measurements of the fundamental constants are tour de force of basic metrology, where the useful information is usually beyond the last digit of the measured value. They…
Finite element analysis of surface-stress effects in the Si lattice-parameter measurement
Carlo Sasso, Danilo Quagliotti, Enrico Massa +2
A stress exists in solids surfaces, similarly to liquids, also if the underlying bulk material is stress-free. This paper investigates the surface stress effect on the measured val…
Elemental characterization of the Avogadro silicon crystal WASO 04 by neutron activation analysis
Giancarlo D'Agostino, Luigi Bergamaschi, Laura Giordani +3
Analytical measurements of the 28Si crystal used for the determination of the Avogadro constant are essential to prevent biased results or under-estimated uncertainties. A review o…
