Description
The n2EDM experiment being mounted at the Paul Scherrer Institute (PSI) will search for the neutron electric dipole moment (nEDM) with at least an order of magnitude better sensitivity than its predecessor at PSI. With the increment in statistical sensitivity, controls of systematic effects must follow. This study targets to investigate the impact of Johnson-Nyquist noise originating from thermal agitations of electrons in the electric conducting materials in the apparatus. Two possible effects are investigated: systematic sensitivity reduction due to the presence of magnetic noise, and a systematic frequency shift, combined with an applied electric field, which could mimic an nEDM signal. Concepts and methods to calculate the magnetic noise and the magnitude of a potential shift are presented.
