In this work, we present a study of two-proton correlation functions measured in Xe+Au collisions at E/A = 50 MeV. The main goal of the analysis consists of understanding the space-time properties of the two-proton emitting source. In order to answer this question, we study transverse momentum gated correlations, guided by indications provided by BUU transport model simulations. The source profiles extracted by imaging techniques are studied to understand to what extent information on the space-time properties of pre-equilibrium stages can be explored. These studies are key to address open problems such as the density dependence of the symmetry energy that affects significantly the dynamical pre-equilibrium neutron/proton emission in heavy-ion collisions.
