Welcome to the nEDM experiment.

 

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 5 x 10^(-28) e-cm as a signature of Charge-Parity (CP) violation. 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.
