Snapshots of our reference simulation K2 at different times (given in T_d units). From top to bottom, left to right: t₁ = 551, t₂ = 2.08 × 10³, t₃ = 8.51 × 10³, t₄ = 1.99 × 10⁴, t₅ = 1.05 × 10⁵, and t₆ = 1.58 × 10⁵. The background color is the logarithm of the density, black lines are the magnetic surfaces, red lines the Alfvén (dotted) and FM (dashed) surfaces, and yellow curves are isocontours of the poloidal electric current.
