Towards Improvements to the Statistical Sensitivity of the ACME Electron EDM Experiment

ORAL

Abstract

Construction of the first generation ACME experiment [A. C. Vutha et al., J. Phys. B 43, 074007 (2010)] to measure the electron electric dipole moment (eEDM) has been completed, and data acquisition and analysis are currently underway. In order to further increase our statistical sensitivity, several improvements are being developed and implemented. We report on: progress towards increasing our total molecule flux with a new beam source; utilizing microwaves, optical pumping, and electrostatic beam focusing to increase the molecule flux in a single state; efficient state preparation via STIRAP; improving detection efficiency by photon cycling; and apparatus redesign to allow more efficient fluorescence collection.
