Background How long one lives, how many years of life are spent in good and poor health,
and how the population's state of health and leading causes of disability change over time …

Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads
to tolerable heat and particle loads on the wall is a major challenge. The new European …

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 …

Sustained edge localized mode (ELM) mitigation has been achieved on MAST and AUG
using resonant magnetic perturbations (RMPs) with various toroidal mode numbers over a …

The role of the pedestal position on the pedestal performance has been investigated in
AUG, JET-ILW and TCV. When the pedestal is peeling-ballooning (PB) limited, the three …

A triggering mechanism responsible for the explosive onset of edge localised modes (ELMs)
in fusion plasmas is identified by performing, for the first time, non-linear …

Edge localized modes (ELMs) are magnetohydrodynamic (MHD) instabilities that cause fast
periodic relaxations of the strong edge pressure gradient in tokamak fusion plasmas. A …

The tokamak is the most advanced approach to fusion and is approaching operation under
power-plant conditions, promising sustainable, low-emission, baseload power to the grid. As …

Prior to eruptive events such as edge localized modes (ELMs), quasicoherent fluctuations,
referred to as pedestal modes, are observed in the edge of fusion devices. We report on the …

Measurements of local density and magnetic field fluctuations near the pedestal top,
conditionally averaged over the edge localized mode (ELM) cycle, have been made in Mega …
