Abstract

We have completed an improved precision measurement of the electron's electric dipole moment using trapped ${HfF}^{+}$ in rotating bias fields. We report on the accuracy evaluation of this measurement, describing the mechanisms behind our systematic shifts. Our systematic uncertainty is reduced by a factor of 30 compared to the first generation of this measurement [Cairncross et al. Phys. Rev. Lett. 119, 153001 (2017)]. Our combined statistical and systematic accuracy is improved by a factor of 2 relative to any previous measurement [Nature (London) 562, 355 (2018)].
