Nonlinear transfer in heated L-modes approaching the L–H transition threshold in Alcator C-Mod

Nonlinear transfer in heated L-modes approaching the L–H transition threshold in Alcator C-Mod

Nonlinear transfer processes between large-scale edge flows and the ambient broadband fluctuations have been shown to play a significant role in the dynamics of edge turbulence, including spreading power from coherent modes and suppressing turbulence at the formation of edge transport barriers. In o...
