System Integration of the ACME III Electron Electric Dipole Moment Search

ORAL

Abstract

A measurement of the electric dipole moment of the electron (eEDM) serves as a powerful probe for CP-violating new physics beyond the Standard Model. The ACME experiment is a spin precession experiment using a cryogenic beam of thorium monoxide.

The third generation of ACME, ACME III, introduces several upgrades: an electrostatic lens, a longer precession region, enhanced fluorescent collection optics, and SIPM detectors, which collectively increase statistical sensitivity by an order of magnitude. Together with improved E field and B field control, we aim to sufficiently suppress known sources of systematic error. We report recent progress on the integration of these upgrades into our experiment.
