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...
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...
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...

We have built a cryogenic current comparator (CCC) resistance bridge for the comparison of standard resistors in the range of 1 Omega-100 kOmega. The use of...
2020 Conference on Precision Electromagnetic Measurements (CPEM), IEEE, 10 septembre 2020
We describe the principles, measurement techniques, error sources and uncertainty contribution of the measurement of the Abbe offset in the NRC Kibble balance....

The next revision to the International System of Units will emphasize the relationship between the base units (kilogram, metre, second, ampere, kelvin, candela...
We describe a project to re-eval uate the transfer of the absolute determination of the local acceleration due to gravity from a nearby site, to the center of...
