Description
The early neutron electric dipole moment (EDM) experiments were performed using continuous beams. They were replaced in the 1980’s with ultracold neutron storage experiments as they provide better sensitivity due to longer observation times. A new approach, the BeamEDM experiment, is based on the early neutron EDM measurements, however, using a pulse beam. This allows to combine a time-of-flight measurement with the classic neutron Ramsey technique [F.M. Piegsa, Phys. Rev. C 88, 045502 (2013)]. This overcomes the previously limiting relativistic vxE-effect by measuring it directly. I will present preliminary results of a recent beam time during which we demonstrated a first time-of-flight measurement using the Ramsey technique.
