|Title:||A One-Kilogram Quartz Resonator as a Mass Standard|
|Published:||February 01, 2013|
|Abstract:||The unit of mass, the kilogram, is the last remaining SI base unit defined by an artifactŠ . This artifact, the primary mass standard, suffers from long term instabilities that are neither well understood, nor easily monitored . A mass standard consisting of a one kilogram quartz resonator is proposed. The frequency stability of such a resonator is likely to be far higher than the mass stability of the primary mass standard, the International Prototype Kilogram. Moreover, the resonator would provide a link to the SI unit of time-interval. When locked to an atomic frequency standard, the frequency of the resonator could be monitored, on a continuous basis, with ultrahigh precision. It could also be coordinated, worldwide, with other resonator mass standards.  Z. J. Jabbour, P. Abbott, E. Williams, R. Liu, and V.
