Electric Dipole Moments, or EDMs, are clean signatures of Charge Parity, or CP, violation. EDM measurements in different mediums are sensitive to different sources of CP violation. This makes measuring EDMs in multiple different systems important. An ideal candidate for EDM measurement is the Ra-225 atom, due to the octupole deformation in its nucleus. This gives it a 2-3 order of magnitude enhancement in sensitivity to CP violation sources in the hadronic sector, compared to such atoms as Hg-199. In the next run of the RaEDM experiment, an improvement of 3 orders of magnitude in sensitivity is planned. To do this, improvements in electric field strength and reversibility are desired, as well as efficiency studies to ensure maximal usage of the rare Ra-225 isotope. At Michigan State University, efforts are ongoing to put these plans into action, with an atomic beam fluorescence setup, as well as a new high voltage switching system.
