Simulation of the signal shape through proposed models for the effect on the spacecraft potential of a transient dust impact. The curve is obtained from the simple model, assuming the electron collect (escape) to be instantaneous, τ_e ≈ 0 (Eq. (16)). The ratio between escaped charge and total charge is ϵ = 0.1, and timescales parameters are τ_sc = 100 μs and τ_ion = 30μs. The zoomed-in portion of the plot (top right) provides an insight into the pre-shoot signal shape.
