Results of the three-dimensional hybrid simulation by the AKA code conducted in a uniform external magnetic field. Panel a: snapshot of the plasma density surrounded by the magnetic pressure. Panels b, c: plasma parameters in the median plane. Panel d: integrated plasma density along the x-axis. Panels e–g: evolution of the central axial lineout for the plasma temperature: (e) ion temperature parallel to magnetic field; (f) perpendicular ion temperature; (g) electron temperature, defined as one-third of the electron pressure tensor divided by density. The temporal and spatial normalization factors are, respectively, ns and d₀ ~ 16 µm (for B₀ = 5 × 10⁵ G and n₀ = 2 × 10²⁰ cm⁻³).
