Fig. 4: Linear modeling results for the DIII-D quiescent-H (QH) mode discharge #184902.
From: How turbulence spreading improves power handling in quiescent high confinement fusion plasmas
a Linear growth rate \(\gamma /{\omega }_{A}\) as a function of toroidal mode number n, where \({\omega }_{A}\) is the Alfvén frequency. The red-shaded region is the peeling-ballooning mode (PBM) dominant, and the blue-shaded region is drift Alfvén wave (DAW) dominant. The critical \({n}_{{crit}}\) = 30 differentiates the PBM and DAW; b Radial mode structure of PBM and DAW.
