Progress in the area of MHD stability and disruptions, since the publication of the 1999 ITER
Physics Basis document (1999 Nucl. Fusion 39 2137–2664), is reviewed. Recent theoretical …

In this work, we address a new feedforward control scheme for the normalized beta (β N) in
tokamak plasmas, using the deep reinforcement learning (RL) technique. The deep RL …

The ITER plasma control system has the same functional scope as the control systems in
present tokamaks. These are plasma operation scenario sequencing, plasma basic control …

Many of the articles in this special issue focus on the problem of control of plasma
axisymmetric shape and position. It is the best understood of tokamak control problems and …

We demonstrate that in a 3D resistive magnetohydrodynamic simulation, for some
parameters it is possible to form a stationary state in a tokamak where a saturated …

We report the results of the first experiments on the DIII-D tokamak to examine the
dependence of the transport and stability characteristics of ITER hybrid scenario plasmas on …

This paper proposes a control-oriented approach to the tokamak plasma current profile
dynamics. It is established based on a consistent set of simplified relationships, in particular …

Ion internal transport barriers (iITBs) are first observed in neutral beam injection (NBI)
heated plasmas at the HL-2A tokamak. The position of the barrier foot, in the stationary state …

Two new main-vessel bolometric cameras (KB5) with horizontal and vertical views of the
plasma cross-section have been installed on JET, providing a substantial upgrade in …

In 2003, the performance of the'hybrid'regime was successfully validated in JET experiments
up to β N= 2.8 at low toroidal field (1.7 T), with plasma triangularity and normalized Larmor …
