Evolution of different energy quantities throughout the simulation R0 in a), calculated as the energy change ΔE = (E(t)−E(0))/E_tot(0), with E the specific energy quantity (magnetic or kinetic) and E_tot the total energy within the system. Energy distributions f(E)≡dN/dE are shown for electrons (b)) and ions (c)) at different times throughout the same simulation. Both panels show the evolution until $t=105{\mathrm{\Omega }}_{0,i}^{-1}$, with darker shades indicating later times. The dashed lines show the initial distribution of each particle species.
