Description

The uniformity of the magnetic field inside the inner part of the n2EDM experiment is a crucial condition to achieve the desired sensitivity of $10^{-28} e \ cm$ for the neutron electric dipole moment (EDM). The magnetic-field mapper is a dedicated nonmagnetic robot designed to measure the magnetic field at any point of a large cylindrical volume ($0 \le \rho \le 780 \ mm$, $0 \le \phi \le 360 ^{\circ}$, $-410 \le z \le 410\ mm$). It was installed in the n2EDM setup in 2021 and has been playing a key role in the n2EDM experiment preparation. Its purpose during the first mapping campaign is to characterize and qualify the inner parts of n2EDM: the remanent field inside the MSR, the production of the $ 1 \mu T$ neutron holding field, the magnetic purity of the octagonal vacuum tank.
