Geodesic acoustic modes (GAMs) are ubiquitous oscillatory flow phenomena observed in
toroidal magnetic confinement fusion plasmas, such as tokamaks and stellarators. They are …

Recent experimental and simulation work has substantially advanced the understanding of
L-mode plasma edge turbulence and plasma flows and their mutual interaction across the L …

A fast edge turbulence suppression event has been simulated in the electrostatic version of
the gyrokinetic particle-in-cell code XGC1 in a realistic diverted tokamak edge geometry …

The efficient operation of a tokamak is limited by several constraints, such as the transition to
high confinement or the density limits occurring in both confinement regimes. These …

In this paper, recent progress on experimental analysis and theoretical models for non-local
transport (non-Fickian fluxes in real space) is reviewed. The non-locality in the heat and …

Transport barrier formation and its relation to sheared flows in fluids and plasmas are of
fundamental interest in various natural and laboratory observations and of critical …

Comprehensive 2D turbulence and eddy flow velocity measurements on DIII-D demonstrate
a rapidly increasing turbulence-driven shear flow that develops∼ 100 μ s prior to the low …

High spatial resolution Doppler backscattering measurements in JET have enabled new
insights into the development of the edge E r. We observe fine-scale spatial structures in the …

A recently developed reduced model of H-mode sustainment based on interchange-drift-
Alfvén turbulence description in the vicinity of the separatrix matching experimental …

Results from recent experiment and numerical simulation point towards a picture of the LH
transition in which edge shear flows interacting with edge turbulence create the conditions …
