Progress toward measuring the electron EDM in a cryogenic beam of polar molecules

POSTER

Abstract

We report on the progress of the ACME Collaboration experiment to measure the electric dipole moment (EDM) of the electron using thorium monoxide. We have demonstrated a statistical sensitivity of $1 \times 10^{-28}$ $\mathrm{e \cdot cm}$ in one day of averaging time. We discuss our studies of several potential sources of systematic error, various apparatus diagnostics, and improvements in the measurement and data analysis scheme.
