Abstract

The redefined kilogram will be realized in vacuum and NIST is developing a magnetic suspension system to disseminate the standard to air. This paper details the progress to characterize and improve the performance of the magnetic suspension portion of the system. Effort has been made to determine the magnetic field within the system through simulation and experiment. To increase stability interferometry is being integrated into the system.
