Description
The search for the neutron electric dipole moment $d_n$, carried on by the n2EDM experiment at PSI could provide a better insight on the baryon asymmetry of the universe and/or new physics. The experimental goal to reach an order of magnitude higher sensitivity than previous efforts, means its systematic effects need to be better controlled. The appearance of a false $d_n$ ($d^{false}_{Hg\rightarrow n}$) due to the different motional magnetic fields seen by the neutrons and Hg atoms of the comagnetometer is one of such obstacles. This study aims at developing and building a Cs-Magnetometer array to measure the magnetic field in the experiment with high-enough precision and accuracy to control the associated systematic uncertainty with $d^{false}_{Hg\rightarrow n}\leq 4 \times 10^{-28}e\textrm{cm}$.
