Using GEM Tracking to Constrain Systematic Uncertainties of Moller Polarimeter at Hall A of Jefferson Lab.

In this conference, we will present our work on using Gas Electron Multiplying (GEM) detectors to improve the accuracy of Moller Polarimeter measurements at Jefferson Lab's Hall A. By utilizing GEM detectors, we can sufficiently reduce the uncertainty caused by the Levchuk Effect and Radiative Corrections, which are major sources of systematic uncertainty in these measurements. Our technique involves using analytically derived mathematical functions to analyze GEM data with the intent of improving the Moller Polarimeter simulation software’s internal physics models, resulting in more accurate measurements of beam polarization.
