Characterization of systematic shifts in the 2<sup>nd</sup> generation JILA eEDM experiment

POSTER

Abstract

Generation II of the JILA eEDM experiment aims to set a new limit on the electron electric dipole moment below 10-29 e cm. The experiment uses hundreds of trapped HfF+ ions, polarized by a rotating electric field and evolving coherently for more than 1 second. We report on our ongoing efforts to study and control systematic shifts in this unique environment for precision metrology. We discuss characterization and suppression of the leading order systematic effects from Generation I as well as new effects that must be considered at our improved sensitivity.
