Comparison of the Josephson Voltage Standards of the NIST and the BIPM



Stephane Solve, Regis Chayramy, Michael Stock, Yi-hua D. Tang, June E. Sims


A comparison of the 10 V Josephson array voltage standard of the Bureau International des Poids et Mesures (BIPM) was made with that of the National Institute of Standards and Technology (NIST), USA, in March 2009. The results are in very good agreement and the measured overall standard relative uncertainty is 1.2 parts in 10^10.
