The redefined kilogram will be realized in vacuum and a method will be required to disseminate the standard to air. NIST has been developing a magnetic suspension system for this purpose. This paper discusses the progress to characterize and improve the performance of the magnetic suspension portion of the system. Effort has been made to accurately describe the magnetic field within the system through simulation and experiment. To increase stability, a more sensitive hall probe has been tested and we are integrating interferometry into the system.
