Experimental searches for a permanent electric dipole moment (EDM) in a fundamental system now date back more than 60 years. An unambiguous manifestation of discrete symmetry violation in both parity (P) and time reversal (T), an EDM directly implies CP violation under the generally accepted assumption of CPT conservation. Confirmed sources of CP violation are insufficient to explain the Universe’s observed matter-antimatter asymmetry, hence new sources of CP violation are naturally interesting to search for.

With the PanEDM experiment at the ILL, we plan to improve this experimental sensitivity of currently 3×10-26 e·cm.by more than an order of magnitude by combining the world’s best-performing magnetic shield with the SuperSUN source of ultra-cold neutrons.

This talk focuses on progress made towards reducing systematic effects in panEDM subsystems and steps towards measurement at the SuperSUN.
