Réalisation et caractérisation de dispositifs de mesure associés à la détermination de la constante de von Klitzing à partir d’un condensateur calculable étalon dit de Thompson-Lampard

Abstract : The comparison of electrical quantities expressed in units of the International System of Units (SI) and the same quantities generated from quantum effects is a direct way of determining physical constants. The determination of the von Klitzing constant (quantum of resistance) from a calculable capacitor is a part of this process. The last determination of this constant was conducted at LNE in 2000 with an uncertainty of 5.10-8. To achieve a target uncertainty of 1.10-8, the LNE decided to build a new standard capacitor and improve the associated measurement chain. The work presented here is implemented in the framework of the design/amelioration and the characterization of the measurement chain leading to the relative uncertainty of 1.10-8. Exploratory studies were also conducted about the possible partial or full automation of elements of the measurement chain.
