This paper reviews current understanding of key physics elements that control the H-mode
pedestal structure, which exists at the boundary of magnetically confined plasmas. The …

Fusion performance in tokamaks hinges critically on the efficacy of the edge transport barrier
(ETB) in suppressing energy losses. The new concept of'fingerprints' is introduced to identify …

The first nonlinear gyrokinetic turbulence simulations that quantitatively reproduce
experimental transport levels in an H-mode pedestal are reported. In the JET-ILW (ITER-like …

Fusion performance has been shown to be related to the H-mode pedestal structure. The
pedestal is associated with steep gradients that are the source of free energy for …

This paper compares the gyrokinetic instabilities and transport in two representative JET
pedestals, one (pulse 78697) from the JET configuration with a carbon wall (C) and another …

Recent evidence points toward the microtearing mode (MTM) as an important fluctuation in
the H-mode pedestal for anomalous electron heat transport. A study of the instabilities in the …

JET has been unable to recover historical confinement levels when operating with an ITER-
like wall (ILW) due largely to the inaccessibility of high pedestal temperatures. Finding a …

Abstract The ASDEX Upgrade (AUG) programme is directed towards physics input to critical
elements of the ITER design and the preparation of ITER operation, as well as addressing …

In a series of discharges on the DIII-D tokamak, fast vertical plasma jogs are used to induce
current perturbations in the steep gradient region of the H-mode edge. These current …

This article presents a global reduced model for slab-like microtearing modes (MTMs) in the
H-mode pedestal, which reproduces distinctive features of experimentally observed …
