The major increase in discharge duration and plasma energy in a next step DT fusion
reactor will give rise to important plasma-material effects that will critically influence its …

The differences and similarities between the internal transport barriers (ITBs) of tokamak and
helical plasmas are reviewed. By comparing the characteristics of the ITBs in tokamak and …

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 …

Observations of divertor plasma detachment in tokamaks are reviewed. Plasma detachment
is characterized in terms of transport and dissipation of power, momentum and particle flux …

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≈ …

During the last decade, significant progress has been made in the field of pellet injection
with (1) the identification of the drift of the deposited material in the inhomogeneous …

The object of this review is to summarize the achievements of research on the Alcator C-Mod
tokamak [Hutchinson et al., Phys. Plasmas 1, 1511 (1994) and Marmar, Fusion Sci. Technol …

ST40 is a compact, high-field (BT0≤ 2.1 T) spherical tokamak (ST) with a mission to expand
the physics and technology basis for the ST route to commercial fusion. The ST40 research …
