<p class="MsoNormal"><span style="font-size:14.0pt">A broad program of important <span class="gmail-il">parity</span>-<span class="gmail-il">violation</span> 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 PVES <span class="gmail-il">experiments</span> in Hall A which 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 PVES experiment searching for new neutral currents, providing an unprecedented <span class="gmail-il">precision</span> on the electron weak charge and electroweak mixing angle.
One common crucial component of all these <span class="gmail-il">experiments</span> is control of helicity correlated false asymmetries in the polarized electron beam. This talk will describe the development of the newly installed RTP Pockels cell system in
the injector source which will enable this <span class="gmail-il">future</span> generation of <span class="gmail-il">experiments</span>. Recent measurements which achieved <30nm position differences in the injector with the RTP cell will also be shown. <o:p></o:p></span></p>
