Oral Presentation

The Electric Dipole Moment (EDM) of the neutron has attracted interest as a promising channel for finding New Physics for a long time. The existence of the neutron EDM would violate CP symmetry given CPT conservation. As a new source of CP violation, the neutron EDM would help answering one of the open questions in fundamental physics: the mystery of the baryon asymmetry in the Universe. The...

Oral Presentation

The TRIUMF Ultracold Advanced Neutron (TUCAN) collaboration has been developing a neutron electric dipole moment (EDM) spectrometer supplied by its high-intensity ultracold neutron (UCN) source. Our room-temperature Ramsey EDM spectrometer features a multilayer magnetically shielded room (MSR), a self-shielded $B_0$​ coil, and other subsystems designed to satisfy the requirements for an EDM...
