Results and Insights for Moller Polarimetry during PREX-2 and CREX

Jefferson Lab’s precision parity-violating electron scattering program has increasingly stringent requirements on the accuracy of beam polarimetry. The M\o ller polarimeter in Hall A was commissioned at low energy and successfully used during the recently completed PREX-2 and CREX experiments to meet the required precision. Along the way the polarimetry teaming gained experience and key insights necessary for the upcoming high-precision program. This talk will focus on the results of M\o ller polarimetry and understanding gained during these past two experiments.
