(a_i) Spatial distribution of density and ion temperature at 25.24 ns, (a_ii) density distribution of Al¹²⁺ ions from the cone walls and ionized aluminum foil after 10.42 ps of acceleration. To better comparison, the density distribution of the accelerated Al¹²⁺ ions from the ionized foil is illustrated at the areas outside the imploded core structure simulation box region (see (a_iii), (b) Al¹²⁺ ions energy spectra after 10.42 ps of acceleration. The inset shows the ions energy-angle distribution after 10.42 ps of acceleration.
