The European Integrated Tokamak Modelling (ITM) effort: achievements and first physics results

Olivier Sauter, Antonio José Pereira de Figueiredo, Emanuele Poli

A selection of achievements and first physics results are presented of the European Integrated Tokamak Modelling Task Force (EFDA ITM-TF) simulation framework, which aims to provide a standardized platform and an integrated modelling suite of validated num ...

Physics of the conceptual design of the ITER plasma control system

Jonathan Bryan Lister, Richard Pitts

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. ...

ELM control strategies and tools: status and potential for ITER

Yves Martin, Minh Quang Tran

Operating ITER in the reference inductive scenario at the design values of Ip = 15 MA and QDT = 10 requires the achievement of good H-mode confinement that relies on the presence of an edge transport barrier whose pedestal pressure height is key to plasma ...

Microphysics of Cosmic Plasmas: Hierarchies of Plasma Instabilities from MHD to Kinetic

Ivo Furno

In this article, we discuss the idea of a hierarchy of instabilities that can rapidly couple the disparate scales of a turbulent plasma system. First, at the largest scale of the system, L, current carrying flux ropes can undergo a kink instability. Second ...

A Shoe-Equipped Linear Generator for Energy Harvesting

Dan Shi, Jianxin Shen

In this paper, a linear tubular generator is presented. It is used for an energy harvesting system equipped in a footwear, scavenging power from forward motion during a walk. Configuration of the generator is studied, and geometric optimization by finite-e ...

Equilibrium and stability in a heliotron with anisotropic hot particle slowing-down distribution

Jonathan Graves, Wilfred Anthony Cooper

The equilibrium and linear fluid Magnetohydrodynamic (MHD) stability in an inward-shifted large helical device heliotron configuration are investigated with the 3D ANIMEC and TERPSICHORE codes, respectively. A modified slowing-down distribution function is ...

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 ...

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 ...

Interpretation of the effects of electron cyclotron power absorption in pre-disruptive tokamak discharges in ASDEX Upgrade

Olivier Sauter, Daniele Brunetti, Hartmut Zohm

Tokamak disruptions are events of fatal collapse of the magnetohydrodynamic (MHD) confinement configuration, which cause a rapid loss of the plasma thermal energy and the impulsive release of magnetic energy and heat on the tokamak first wall components. T ...

On the locality of MHD turbulence scale fluxes

The scale locality of energy fluxes for magnetohydrodynamics (MHD) is investigated numerically for stationary states of turbulence. Two types of forces are used to drive turbulence, a kinetic force that acts only on the velocity field and a kinetic-inducti ...
