"Source Studies and Polarimetry for Upcoming PREX-II and CREX Experiments "
ABSTRACT:

Parity-violating electron scattering provides a clean probe of neutron densities that is model independent and free from most of the strong interaction uncertainties. The PREX-II and CREX experiments at Jefferson lab aim to measure the nucleon skin thickness in 208Pb and 48Ca via parity violating electroweak asymmetry in the elastic scattering of left and right polarized electrons. These measurement from Pb and Ca are sensitive to the existence of this neutron skin and it will provide information on nuclear structure. Knowledge of difference in proton and neutron radius or an effective neutron skin thickness is required in order to calibrate the equation of state for neutron rich nuclear matter.

I will discuss how we are getting ready for the upcoming 2019 runs of both experiments, especially focused on source studies and polarimetry studies.
