B7.2 - Monolithic Guiding Mechanism and Adjustment Devices for an Electrostatic Force Balance at LNE

Abstract

A measurement apparatus that uses an electrostatic force generator is being developed at LNE, toward the realization of small masses and forces in the International System of Units (SI). Two of the main parts are designed, i.e. a parallelogram balance mechanism, and two capacitance actuators. The balance mechanism is fully monolithic as well as the two adjustment systems of the electrostatic actuators. Special attention has been paid to the overall symmetry of the system and to cost efficiency.
