Description
Electric Dipole Moments, or EDMs, are a clean signature of Charge Parity, or CP violation. Measurements of EDMs in different atoms and molecules correspond to different sources of CP violation. This makes measuring multiple EDMs in different mediums important. One of the best atoms to measure is Ra-225, due to the octupole deformation in its nucleus. This gives it an enhancement factor on the order of 2-3 orders of magnitude in sensitivity to CP violating sources in the hadronic sector compared to such atoms as Hg-199. In the next EDM measurement run, an improvement in sensitivity of 3 orders of magnitude is being planned. This improvement will utilize upgrades in most aspects of the experiment. In particular, the electric field applied for the EDM measurement will be made larger and more reversible, and studies will be performed to improve the efficiency with which isotopes harvested from FRIB can be used.
