31.08.2023 GRK-NanoFab-Kolloquium: "Kilogram Realization in NIM" Dr. Yang Bai from the National Institut of Metrology, China
As from May 20 2019, the kilogram was redefined based on the Planck Constant. The National Institute of Metrology (NIM), China has built up the Joule Balance to realize the kilogram from the Planck Constant. This presentation will introduce the basic theory, essential technical details of Joule Balance and show its performance in two CCM key comparisons of kilogram realizations (CCM.M-K8). In addition, this presentation will talk about two generations of heterodyne laser interferometer in the Joule Balance in detail.
