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 …

Experimental observations of driven and intrinsic rotation in tokamak plasmas are reviewed.
For momentum sources, there is direct drive from neutral beam injection, lower hybrid and …

The relation between the macroscopic input power required at ASDEX Upgrade to access
the H-mode Pthr and the microscopic E× B shear has been investigated via fast charge …

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 …

The spatio-temporal interplay between turbulence, mean and zonal flows has been
investigated at the L–H and H–L transitions in the edge region of the ASDEX Upgrade …

Limit-cycle oscillations (LCOs) close to the power threshold of L-to H-mode transitions are
investigated in plasmas of ASDEX Upgrade. During this phase, referred to as I-phase, a …

Electric field profile structure—especially its shear—is a natural order parameter for the edge
plasma, and characterizes confinement regimes ranging from the H-mode (Wagner et al …

This paper presents investigations on the role of the edge ion heat flux for transitions from L-
mode to H-mode in Alcator C-Mod. Previous results from the ASDEX Upgrade tokamak …

The transition dynamics from low (L) to high (H) mode confinement in magnetically confined
plasmas is investigated using a four-field drift fluid model—HESEL (Hot Edge-Sol …

In order to inform core performance projections and divertor design, the baseline SPARC
tokamak plasma discharge is evaluated for its expected H-mode access, pedestal pressure …
