Recent ASDEX Upgrade research in support of ITER and DEMO

Basil Duval, Timothy Goodman, Olivier Sauter, Stefano Coda, Alberto Bottino, Marco Wischmeier, Andrea Scarabosio, Hartmut Zohm, Laurie Porte, Yann Camenen, Thomas Binderup Jensen, Emiliano Fable, Federico Alberto Alfredo Felici, Dávid Wágner, Doohyun Kim, Heinz Mueller, Emanuele Poli, Nicola Vianello, Giovanni Tardini, Donghyun Kim, Alessandro Pau, Otto Asunta, Haomin Sun, Xiao Wang, Gergely Papp, Bernhard Sieglin

Recent experiments on the ASDEX Upgrade tokamak aim at improving the physics base for ITER and DEMO to aid the machine design and prepare efficient operation. Type I edge localized mode (ELM) mitigation using resonant magnetic perturbations (RMPs) has been ...

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

Minh Quang Tran, Hartmut Zohm, Laurie Porte, 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 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

Timothy Goodman, Olivier Sauter, 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 ...

Advances in the physics basis for the European DEMO design

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

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 ...

Electron-cyclotron-current-drive efficiency in DEMO plasmas

Hartmut Zohm, Laurie Porte, Emiliano Fable, 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 ...

Preliminary design of the ITER ECH Upper Launcher

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

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 ...

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

Olivier Sauter, Hartmut Zohm, Daniele Brunetti

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 ...

Overview of the ITER EC H&CD system and its capabilities

Stefano Alberti, René Chavan, Timothy Goodman, Olivier Sauter, Minh Quang Tran, Jean-Philippe Hogge, Jean-Daniel Landis, Hartmut Zohm, Laurie Porte, Robert Bertizzolo, Francisco Sanchez, Ioannis Pagonakis, Emanuele Poli

The Electron Cyclotron (EC) system for the ITER tokamak is designed to inject >= 20 MW RF power into the plasma for Heating and Current Drive (H&CD) applications. The EC system consists of up to 26 gyrotrons (between 1 and 2 MW each), the associated power ...

On the heating mix of ITER

Olivier Sauter, Minh Quang Tran, Frank Rüdiger Wagner, Hartmut Zohm, Costanza Zucca

This paper considers the heating mix of ITER for the two main scenarios. Presently, 73MWof absorbed power are foreseen in the mix 20/33/20 for ECH, NBI and ICH. Given a sufficient edge stability, Q = 10 the goal of scenario 2 can be reached with 40MW power ...

On the Requirements to Control Neoclassical Tearing Modes in Burning Plasmas

Olivier Sauter, Hartmut Zohm, Costanza Zucca

Neoclassical tearing modes (NTMs) are magnetic islands which increase locally the radial transport and therefore degrade the plasma performance. They are self-sustained by the bootstrap current perturbed by the enhanced radial transport. The confinement de ...
