bstract: A broad program of important parity-violation measurements in electron scattering from heavy nuclei will constrain nuclear structure models as well as search for new BSM physics.
PREX and CREX are upcoming experiments at Jefferson Lab that aim to map the weak charge distribution in nuclei, with implications for the equation of state of highly dense matter, neutron stars, and gravitational waves produced in neutron star collisions.
MOLLER is another upcoming experiment searching for new neutral currents, providing an unprecedented precision on the electron weak charge and electroweak mixing angle.
One common crucial component of all these experiments is control of helicity-correlated false asymmetries in the polarized electron beam. This talk will describe the development of a new Pockels cell system for the laser optics of the electron source that will enable this future generation of experiments.
