Experiment to measure the electric dipole moment (edm) of the electron using laser-cooled Cs atoms

The electron edm $d_{e}$ is known to be smaller in magnitude than $1.6\times 10^{-27}$\textit{e$\cdot $cm} [1]. We will describe progress on an ongoing experiment designed to be sensitive to an electron EDM $d_{e}$ as small as $10^{-29}$\textit{e$\cdot $cm.} The experiment will search for the resulting edm of the Cs atom, proportional to $d_{e}$, using laser-cooled Cs atoms held in an optical dipole force trap. Important features of the experiment include resonant optical cavities to accurately define the trapping laser field, in-vacuum high voltage electrodes, and methods to reduce magnetic noise to low levels, including the use of a novel titanium vacuum chamber \\[4pt] [1] B.
