Geodesic acoustic modes (GAMs) are ubiquitous oscillatory flow phenomena observed in
toroidal magnetic confinement fusion plasmas, such as tokamaks and stellarators. They are …

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 …

The efficient operation of a tokamak is limited by several constraints, such as the transition to
high confinement or the density limits occurring in both confinement regimes. These …

In this paper, recent progress on experimental analysis and theoretical models for non-local
transport (non-Fickian fluxes in real space) is reviewed. The non-locality in the heat and …

In this Letter, we report analyses of spatiotemporal dynamics of turbulence and structure in
the limit-cycle oscillation (LCO) that precedes an L-to-H transition. Zonal flows are not …

A major scientific success story of magnetic fusion research in the past several decades has
been the theoretical development and experimental testing of the process of turbulence …

To study the impact of strong impurity radiation on the energy confinement and the
discharge stability at JET-ILW, dedicated high-density, highly heated experiments with neon …

The hysteresis relation between turbulence and temperature modulation during the heat
pulse propagation into a magnetic island is studied for the first time in toroidal plasmas …

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 …
