Electron and ion densities at the final simulation time, t=1.5 s, are shown for run A (columns 1 and 2) and run B (columns 3 and 4) as 2D slices in the XY and XZ plane: row 1a-4a for ambient electrons (AE), row 1b-4b for photoelectrons (PE), row 1c-4c for secondary electrons from electron impacts (SE), row 1d-4d total electron density (AE+PE+SE+SI), and row 1e-4e for ambient ion density (AI). All densities are normalized to the initial ambient plasma density, n₀, and plotted on a logarithmic scale showing a relative increase in densities in red and decrease in densities in blue.
