Description
The n2EDM experiment at the Paul Scherrer Institute aims to measure the neutron electric dipole moment with a sensitivity of below 1E−27 e⋅cm by observing neutron spin precession in a near perfectly uniform magnetic field. Precise control of systematic effects, particularly those caused by magnetic field non-uniformities, is crucial for achieving this sensitivity. To address this, an array of 112 optically pumped Cesium vapor magnetometers, capable of picotesla-level precision measurements, will be deployed. This system will provide real-time measurements of magnetic field gradients, enabling the control and reduction of systematic uncertainties arising from magnetic field non-uniformities. In this contribution, the design, performance, and integration of this system into the experimental setup will be presented.
