Snapshot of fluctuation data in the quasi-stationary state for baseline case 1, with ω_n = 100, $\hat{s}=0.25,$ and in the electrostatic limit. Shown are the electrostatic potential (Φ; where the dominant vertical structures correspond to a zonal flow), ion number density (n; the ion and electron density fluctuations are identical due to the quasi-neutrality constraint), and the parallel and perpendicular ion temperatures (T_∥ and T_⊥).
