Nuclear fusion is one of the most attractive alternatives to carbon-dependent energy
sources. Harnessing energy from nuclear fusion in a large reactor scale, however, still …

Edge-localized-modes (ELMs) are a ubiquitous feature of H-mode in tokamaks. When
gradients in the H-mode transport barrier grow to exceed the MHD stability limit the ELM …

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 …

Type-I edge-localized modes (ELMs) have been mitigated at the JET tokamak using a static
external n= 1 perturbation field generated by four error field correction coils located far from …

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 …

Since the first H-mode discharges in 2010, the duration of the H-mode state has been
extended and a significantly wider operational window of plasma parameters has been …

An overview of results of negative triangularity (NT) studies from the ASDEX Upgrade
tokamak (AUG) is given. Moderate values of the triangularity in the range of δ average≈ …

Operating ITER in the reference inductive scenario at the design values of I p= 15 MA and Q
DT= 10 requires the achievement of good H-mode confinement that relies on the presence …

As part of the ITER Design Review and in response to the issues identified by the Science
and Technology Advisory Committee, the ITER physics requirements were reviewed and as …

In ASDEX Upgrade, experimental efforts aim to establish pace making and mitigation of type-
I edge localized modes (ELMs) in high confinement mode (H-mode) discharges. Injection of …
