Measurements of the neutron electric dipole moment (EDM) over the past sixty years, most recently at the ILL and now at PSI, have pushed its upper limit to ever lower levels. During that time, the absence of an observable EDM has limited numerous theories of new subatomic physics. Particular beyond-the-standard-model theories, such as supersymmetry, tend to predict as much CP-violation as current EDM limits allow. Even the observed cosmological excess of baryons over anti-baryons may be explained by new CP-violation manifest in the neutron EDM. I will describe the design and status of the neutron EDM experiment at the ORNL Spallation Neutron Source, which borrows a number of features pioneered at ILL and adds a few new ones.
