On recent results in the modelling of neoclassical-tearing-mode stabilization via electron cyclotron current drive and their impact on the design of the upper EC launcher for ITER

Olivier Sauter, Timothy Goodman, Hartmut Zohm, Emanuele Poli

Electron cyclotron wave beams injected from a launcher placed in the upper part of the vessel will be used in ITER to control MHD instabilities, in particular neoclassical tearing modes (NTMs). Simplified NTM stabilization criteria have been used in the pa ...

Technological and physics assessments on heating and current drive systems for DEMO

Minh Quang Tran, Laurie Porte, Hartmut Zohm, Emanuele Poli, Giovanni Tardini

The physics requirements of the heating and current (H&CD) systems in a Demonstration Fusion Power Plant (DEMO) are often beyond the actual level of design maturity and technology readiness required. The recent EU fusion roadmap advocates a pragmatic appro ...

On the criteria guiding the design of the upper electron-cyclotron launcher for ITER

Olivier Sauter, Timothy Goodman, Hartmut Zohm, Emanuele Poli

Electron cyclotron waves injected from an antenna located in the upper part of the vessel will be employed in ITER to control MHD instabilities, particularly neoclassical tearingmodes (NTMs). The derivation of the NTM stabilization criteria used up to now ...

Advances in the physics basis for the European DEMO design

Ambrogio Fasoli, Javier García Hernández, Marco Wischmeier, Emiliano Fable, Bernhard Sieglin, Hartmut Zohm, Emanuele Poli

In the European fusion roadmap, ITER is followed by a demonstration fusion power reactor (DEMO), for which a conceptual design is under development. This paper reports the first results of a coherent effort to develop the relevant physics knowledge for tha ...

On the physics guidelines for a tokamak DEMO

Olivier Sauter, Laurie Porte, Marco Wischmeier, Emiliano Fable, Hartmut Zohm, Emanuele Poli, Giovanni Tardini

The physics base for the ITER Physics Design Guidelines is reviewed in view of application to DEMO and areas are pointed out in which improvement is needed to arrive at a consistent set of DEMO Physics Design Guidelines. Amongst the proposed improvements, ...

Electron-cyclotron-current-drive efficiency in DEMO plasmas

Laurie Porte, Emiliano Fable, Hartmut Zohm, Emanuele Poli, Giovanni Tardini

The achievable efficiency for external current drive through electron-cyclotron waves in a demonstration tokamak reactor is investigated. Two possible reactor designs, one for steady state and one for pulsed operation, are considered. Beam propagation, abs ...

Non-linear magnetic perturbations during edge-localized modes in TCV dominated by low n mode components

Olivier Sauter, Holger Reimerdes, Hartmut Zohm

Edge-localized modes (ELMs) are instabilities in the edge of tokamak plasmas in the high confinement regime (H-mode). Despite beneficial aspects of ELMs, in a future device the size of the energy loss per ELM must be controlled, in order to avoid intolerab ...

Preliminary design of the ITER ECH Upper Launcher

Olivier Sauter, Timothy Goodman, René Chavan, Jean-Daniel Landis, Francisco Sanchez, Hartmut Zohm, Emanuele Poli

The design of the ITER electron cyclotron launchers recently reached the preliminary design level - the last major milestone before design finalization. The ITER ECH system contains 24 installed gyrotrons providing a maximum ECH injected power of 20 MW thr ...
