We propose a quasi-neutral single-fluid plasma model capturing long-term plasma dynamics relevant for plasma accelerators. The model uses two temperatures (for atoms and electrons, respectively) and the plasma composition is tracked via collisional reaction rates.
We will present simulation results capturing the full dynamics of hydrodynamic optical-field-ionized (HOFI) channels [R. J. Shalloo et al., Phys. Rev. E 97, 053203 (2018)], and show comparisons to measurements, and explore the effect of the main parameters on the channel properties.
