Description
The n2EDM experiment, presently under construction at PSI, aims at searching for the neutron electric dipole moment $d_n$, with at least an order of magnitude higher sensitivity than previous efforts. The systematic uncertainties must be better controlled than in the predecessor experiment. Due to different motional magnetic fields seen by the neutrons and Hg atoms of the co-magnetometer, a false $d_n$ ($d^{false}_{Hg \rightarrow n}$) arises, which is one of the most challenging obstacles. This study focuses on developing a Cs-Magnetometer (CsM) array to measure the magnetic field in the experiment to high enough precision and accuracy, to control the associated systematic in the order of $\Delta d^{false}_{Hg \rightarrow n}<5\times10^{−28}~$e.cm. The requirements, features and limitations of the array are here presented.
