This paper presents a comprehensive analysis of the alignment uncertainties in the NRC watt balance. We show that, due to the use of a beam balance in both...
We present a summary of the Planck constant determinations using the NRC watt balance, now referred to as the NRC Kibble balance. The summary includes a...
2014 Conference on Precision Electromagnetic Measurements (CPEM 2014), IEEE, août 2014
A 10 V programmable Josephson voltage standard system has been installed at the National Research Council Canada. The current margins for the first Josephson...
This report describes the second CCM key comparison of realizations of the kilogram definition based on the fixed numerical value of the Planck constant, which...
In March 2009, the Consultative Committee for Electricity and Magnetism (CCEM) reviewed and re-endorsed its recommendations originally proposed during its 25th...
We have measured Planck's constant and have obtained a value of 6.626 070 34(12) × 10-34 J s. To our knowledge this measurement of h has the lowest uncertainty...
In a watt balance (WB) the gravity on a known mass is used in the determination of the value of the Planck constant with a precision of <2 × 10-41 J s. To...
