Neutron Electric Dipole Moment measurement: simultaneous spin analysis and preliminary data analysis

Abstract : In the framework of the neutron Electric Dipole Moment (nEDM) experiment at the Paul Scherrer Institut (Switzerland), this thesis deals with the development of a new system of spin analysis. The goal here is to simultaneously detect the two spin components of ultra cold neutrons in order to increase the number of detected neutrons and therefore lower the nEDM statistical error. Such a system has been designed using GEANT4-UCN simulations, built at LPC Caen and then tested as part of the experiment. In parallel to this work, the 2013 nEDM data taken at PSI have been analysed. Finally, methods to recover magnetic observables of rst interest to control nEDM systematic errors have been studied and possible improvements are proposed.
