Measuring the Efficiency of Atomic Beam Sources Using Harvested Isotopes at FRIB for Fundamental Symmetry Measurements with Improved Precision
ORAL
Abstract
Nuclei such as Radium-225 or Radium-223 are proposed to have an enhanced sensitivity to Electric Dipole Moment (EDM) measurements. Beams producing these kinds of isotopes will be produced in the water beam dump at the Facility for Rare Isotope Beams (FRIB) at Michigan State University. We will report our efforts to measure the efficiency of forming an atomic beam from these harvested isotopes using laser-induced fluorescence on chemical surrogates. In addition, we report efforts to improve the reversability of the electric field in our EDM measurement by using a unipolar power supply.
