a Location of bulk plasma–afterglow boundary, γ0, as a function of pressure, calculated using a power dissipation model (solid black line). γ0 values obtained by fitting the model to DLP measurements are also shown for comparison (red star data points). b Thiele modulus, ϕ, as a function of pressure, calculated using the approximate linear relationship for the bulk plasma density (solid black line). Values of ϕ reflecting experimental conditions are also shown for comparison (red star data points). c Dimensionless charge density, η, as a function of dimensionless axial distance, ξ, in the spatial afterglow for different values of ϕ calculated using an advection-diffusion-recombination model (solid lines). Experimental values obtained by DLP measurements are also shown for comparison (data points). At least four measurements were made at each of the five spatial positions, and error bars correspond to one standard deviation.
