Physics of the conceptual design of the ITER plasma control system

The ITER plasma control system (PCS) will play a central role in enabling the experimental program to attempt to sustain DT plasmas with Q = 10 for several hundred seconds and also support research toward the development of steady-state operation in ITER. ...

Three-dimensional distortions of the tokamak plasma boundary: boundary displacements in the presence of saturated MHD instabilities

Jonathan Graves, Wilfred Anthony Cooper, Daniele Brunetti

The three-dimensional plasma boundary displacement induced by long-lasting core magnetohydrodynamic (MHD) instabilities has been measured in JET, MAST and NSTX. Only saturated instabilities are considered here since transient rapidly growing modes which de ...

Observation of Edge Instability Limiting the Pedestal Growth in Tokamak Plasmas

Christian Gabriel Theiler

With fusion device performance hinging on the edge pedestal pressure, it is imperative to experimentally understand the physical mechanism dictating the pedestal characteristics and to validate and improve pedestal predictive models. This Letter reports di ...

Plasma turbulence in the scrape-off layer of tokamak devices

Paolo Ricci

Plasma turbulence is explored in the scrape-off layer of tokamak devices using three-dimensional global two-fluid simulations. Two transport regimes are discussed: one in which the turbulent fluctuations saturate nonlinearly due to the Kelvin-Helmholtz ins ...

Integrated real-time control of MHD instabilities using multi-beam ECRH/ECCD systems on TCV

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Federico Alberto Alfredo Felici, Jonathan Rossel

Simultaneous real-time control of multiple MHD instabilities is experimentally demonstrated in the TCV tokamak. Multiple sources of EC heating and current drive, injected through real-time controlled launchers, are used to stabilize 3/2 and 2/1 neoclassica ...

Bifurcated Helical Core Equilibrium States in Tokamaks

Olivier Sauter, Basil Duval, Stefano Coda, Jonathan Graves, Wilfred Anthony Cooper, Holger Reimerdes, Benoît Labit, Antoine Pochelon, David Pfefferlé, Federico David Halpern, Daniele Brunetti, Jonathan Rossel, Mattia Albergante

Tokamaks with weak to moderate reversed central shear in which the minimum rotational transform

q_{min}

is in the neighbourhood of unity can trigger bifurcated MagnetoHydrodynamic (MHD) equilibrium states, one of which is similar to a saturated ideal ...
