The neutron EDM project at PSI

We propose to perform a new high precision measurement of the neutron Electric Dipole Moment (nEDM). Our goal is to reach an accuracy of $5\times10^{-28}$ e.cm or better, i.e an improvement of nearly two orders of magnitude over the present best measurement. Our experiment will use the new spallation UCN source under construction at the Paul Scherrer Institute and will optimize the in vacuum Ramsey resonance technique at room temperature.
