The JET programme in 2019–2020 focussed on preparing for the exploitation of JET's
currently unique capabilities, tritium handling and ITER-like wall (ILW: Be first wall and W …

In this paper, we review the thermal plasma confinement and transport properties observed
and predicted in low aspect ratio tokamaks, or spherical tokamaks (STs), which can depart …

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 …

We present the results of GENE gyrokinetic calculations based on a series of JET–ITER-like-
wall (ILW) type I ELMy H-mode discharges operating with similar experimental inputs but at …

In this paper, we present linear and nonlinear gyrokinetic analyses in the pedestal region of
two DIII-D ELMy H-mode discharges using the CGYRO code. The otherwise matched …

A reduction of the pedestal pressure with increasing separatrix density over pedestal density
(ne sep/ne ped) has been observed in JET. The physics behind this correlation is …

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 …

This paper reports on the development of reduced models for electron temperature gradient
(ETG) driven transport in the pedestal. Model development is enabled by a set of 61 …

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 …
