Energy distribution for the main simulation (Sect. 3.1), with a background magnetization for ions and electrons , respectively. Top: energy in the total electric field E_tot, in the x component of the magnetic field, and in the particles (also decomposed into the ion and electron contributions). These energies are computed on a fixed area that corresponds to the location of the background particles, or field lines, that reach the current sheet before the end of the simulation. The total initial energy in this area is ℰ₀. We note that the energy in E_tot is mostly the energy in the y component E_y. Also, the energy of B_y is 0.5% of the energy of B_x. Bottom: orange and blue curves are the energy distribution between ions and electrons for the current sheet particles (dashed), and for the background particles that have been accelerated (solid). They are normalized so that their sum is 1. The red and green curve show the energy repartition between current sheet particles and background accelerated particles.
