Abstract
We revisit the Kibble-Robinson Theory (KRT), first proposed in 2014 by Kibble and Robinson, which significantly simplifies the construction and operation of Kibble balances. We conducted a theoretical investigation of the theory's assumptions, using a corner cube as the optical target in the interferometer for velocity measurement. We find that it is advantageous to build a mechanism whose output has minimal rotation and horizontal motion. For balances with relative uncertainty targets below \SI1e-6}}, the mass pan and the optical target should be suspended from a common gimbal so they have the same vertical velocity and no rotation. In this case, the measurement biases due to Abbe offset and corner loading are small.Citation
