La co-magnétométrie mercure pour la mesure du moment électrique dipolaire du neutron : Optimisation et application au test de l'invariance de Lorentz

Abstract : In this thesis, magnetometry is studied in the context of the neutron Electric Dipole Moment (nEDM) measurement with the RAL/Sussex/ILL spectrometer. In particular, the pre-existing mercury co-magnetometer has been modeled and optimized to be used in the next nEDM measurement at the Paul Scherrer Institut (Villigen Suisserland) in 2010-2012. Using data taken at the Institut Laue-Langevin (Grenoble, France), the complementarity between external cesium magnetometry and mercury co-magnetometry has been studied, bringing two results : - a best way to control systematics due to the co-magnetometer - a limit on the neutron anomalous couplings that violates Lorentz invariance.
