Development and validation of a predictive model for the pedestal height
The pressure at the top of the edge transport barrier (or “pedestal height”) strongly impacts tokamak fusion performance. Predicting the pedestal height in future devices such as ITER [ITER Physics… Expand
Magnetohydrodynamic stability of tokamak edge plasmas
A new formalism for analyzing the magnetohydrodynamic stability of a limiter tokamak edge plasma is developed. Two radially localized, high toroidal mode number n instabilities are studied in detail:… Expand
Theory for explosive ideal magnetohydrodynamic instabilities in plasmas.
Flux tubes confined in tokamaks are observed to erupt explosively in some plasma disruptions and edge localized modes. Similar eruptions occur in astrophysical plasmas, for example, in solar flares… Expand
Spatial and temporal structure of edge-localized modes.
This Letter provides information on the spatial and temporal structure of periodic eruptions observed in magnetically confined laboratory fusion plasmas, called edge-localized modes (ELMs), and… Expand
Evolution of filament structures during edge-localized modes in the MAST Tokamak.
Edge-localized modes (ELMs) are repetitive instabilities that occur in the outer region of tokamak plasmas. This Letter provides new information on and the implications of the evolution of the… Expand
Inter-ELM filaments and turbulent transport in the Mega-Amp Spherical Tokamak
Results on edge turbulence in periods separating edge localised modes (ELMs), i.e. inter-ELM periods, in Mega-Amp Spherical Tokamak (MAST) are presented. It is shown through combined measurements of… Expand
REVIEW ARTICLE: A review of theories of the L-H transition
After a general discussion of the experimental characteristics of the L-H transition and consideration of basic theoretical principles underlying models for it, this paper reviews the various… Expand
Overview of the JET results in support to ITER
The 2014-2016 JET results are reviewed in the light of their significance for optimising the ITER research plan for the active and non-active operation. More than 60 h of plasma operation with ITER… Expand

Plasma equilibria reconstructed from the Mega-Amp Spherical Tokamak have sufficient resolution to capture plasma evolution during the short period between edge-localized modes (ELMs). Immediately… Expand
Threshold for neoclassical magnetic islands in a low collision frequency tokamak
A kinetic theory for magnetic islands in a low collision frequency tokamak plasma is presented. Self‐consistent equations for the islands’ width, w, and propagation frequency, ω, are derived. These… Expand
