The equilibrium parallel current u 0 (a) and its derivative (b) used in simulation.
The linear growth rate γ (a) and real frequency (b) for . Solid line: results with the parallel current; dashed line: without the parallel current.
The poloidal cross sections of the linear mode structure for n = 6 (left panel) and n = 36 (right panel).
The (a) linear growth rate and (b) real frequency of the KPBM of n = 12 with changing half width of one of the three profiles: density, ion temperature, and electron temperature—while keeping the other two profiles fixed. is the factor used to multiply the profile width.
Similar to Fig. 4 but for the high-n mode, n = 54.
Half width scan for (a) discharge 132016, n = 36, and (b) discharge 136051, n = 63. Collisions are not included in (a) for cleaner trends.
The experimental radial electric field Er (solid line) compared to (dashed line).
The nonlinear evolution of volume-averaged particle flux. (a) Simulation with the intermediate-n KPBM included; (b) simulations with high-n ( ) modes only. Solid lines are results with Er and dashed lines are without Er .
The nonlinear turbulence structure. The electrostatic potential for the simulations with (a) the KPBM and (b) high-n only. Er is included in these runs.
The particle diffusion coefficient D across the pedestal for the four nonlinear simulations of Fig. 8 . Quantities are time-averaged over the nonlinear saturation stage.
