Description

The NL-eEDM experiment aims to set a new limit on the permanent electric dipole moment of the electron (eEDM), in order to constrain CP-violation as it appears in many standard model extensions. We use an all-optical method to probe properties of the barium-fluoride (BaF) molecule. A novel spin-precession method permits identification of possible false EDM signals from the optical signal[1].

The experiment has recently been moved to a new laboratory and is currently in the process of reassembly. We will discuss the conclusions from previous data runs and current improvements of the experimental procedure.
