| Abstract: |
We describe a mass comparison system in which a test mass artifact in air can be directly compared to a standard mass artifact in vacuum using the same high precision comparator balance. The system uses a magnetic levitation technique to couple the weighing pan of the comparator balance in vacuum to the test mass in air. We will discuss motivation, design considerations, and preliminary results. |
