Abstract :
This paper describes the progress on the implementation of a calculable cross capacitor for the measurement of RK at the BIPM. The main electrodes are installed and the alignment process has been demonstrated. The optical interferometer required to measure the guard displacement is operational. The chain of bridges for the transfer from RK to 1 pF exists, and first measurements can be expected during 2012.
