Abstract

Experiments to realize the new definition of the kilogram will be carried out in vacuum. NIST has developed a magnetic suspension mass comparator to disseminate the new definition to air. This paper details the current status of the system. This includes results from recent work to characterize and improve the performance of the magnetic suspension portion of the system. A general overview of the system, as well as key results are given.
