Internal transport barriers in tokamak plasmas are explored in order to improve confinement
and stability beyond the reference scenario, used for the ITER extrapolation, and to achieve …

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 …

The understanding and predictive capability of transport physics and plasma confinement is
reviewed from the perspective of achieving reactor-scale burning plasmas in the ITER …

High-confinement (H-mode) operation is the choice for next-step tokamak devices based
either on conventional or advanced tokamak physics. This choice, however, comes at a …

H-mode operation is the choice for next-step tokamak devices based either on conventional
or advanced tokamak physics. This choice, however, comes at a significant cost for both the …

Plasma profiles across the separatrix and scrape-off layer (SOL) in Alcator C-Mod are
examined for a range of plasma densities, currents and magnetic fields in Ohmic L-mode …

A stationary H-mode without edge localized modes (ELMs) has been recently achieved in
the ASDEX Upgrade tokamak by applying central electron cyclotron resonance heating …

Direct measurements of the pedestal recovery during an edge-localized mode cycle provide
evidence that quasi-coherent fluctuations (QCFs) play a role in the inter-ELM pedestal …

We present the results of experiments in JET to study the effect of plasma shape on high
density ELMy H-modes, with geometry of the magnetic boundary similar to that envisaged …
