Search for neutron Electric Dipole Moment at Spallation Neutron Source

The goal of the nEDM experiment at the Spallation Neutron Source (SNS) is to search for a neutron electric dipole moment (EDM) with a sensitivity below \( 3 \times 10^{-28}\) e-cm as a signature of Charge-Parity (CP) violation. New sources of CP violation are required to explain the dominance of Matter over Antimatter in the Universe. The experiment uses spallation neutrons from the SNS at Oak Ridge National Laboratory that are cooled with superfluid 4He. A novel 3He co-magnetometer is also a key component of the experiment in order to limit systematic uncertainties.
