Description
The dominant systematic in the n2EDM experiment is the false EDM effect. Magnetic field inhomogeneities in the presence of an electric field generate an electric-field correlated shift in the measured frequencies, effectively mimicking a "false" electric dipole. To correct for this effect, a dedicated array of optically pumped Cesium vapor magnetometers is used to perform online measurements of higher order magnetic field gradients.
In this overview talk, we present the measurement principle, hardware implementation, and operation of this array within the n2EDM apparatus.
