Characterizing the plasma density profile in a plasma accelerator is important for predicting the beam dynamics and the electric field gradients produced in the plasma wake structure. In this poster, we present a two fluid model for the time evolution of the plasma and neutral gas density profiles for a laser ionized plasma filament. Our model includes the effects of hydrodynamic expansion and recombination. We compare our model with experimental measurements of a laser ionized Ar and He plasma that is $\sim .5 \, mm$ wide and $\sim 100 \, cm$ long with densities $10^{15−17} cm^{-3}$.
