Nearing final design of the ITER EC H&CD Upper Launcher

Olivier Sauter, Timothy Goodman, René Chavan, Jean-Daniel Landis, Robert Bertizzolo, Matteo Vagnoni, Florian Ramseyer, Emanuele Poli

The ITER ECRH system consists of 24 gyrotrons with up to 24 MW installed millimeter wave heating power at 170 GHz, power supplies, control system, transmission lines, one Equatorial and the four Upper Launchers. With its high frequency and small beam focus ...

Mechanical analyses of the waveguide flange coupling for the first confinement system of the ITER electron cyclotron upper launcher

Timothy Goodman, René Chavan, Jean-Daniel Landis, Robert Bertizzolo

The four electron cyclotron (EC) upper port antennas (or "upper launchers" -UL) will be used to drive current locally inside magnetic islands located at the q= 2 (or smaller) rational surfaces in order to stabilize neoclassical tearing modes (NTMs), as wel ...

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

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

Design status of the ITER ECRH upper launcher mm-wave system

René Chavan, Federico Alberto Alfredo Felici, Jean-Daniel Landis, Frédéric Dolizy, Francisco Sanchez, Robert Bertizzolo

The purpose of the ITER electron cyclotron resonance heating (ECRH) upper launcher (UL), or antennae will be to provide localised current drive by accurately directing mm-wave beams up to 2MW, out of the four allocated upper port plugs, at chosen rational ...

Design and manufacturing of the ITER ECRH Upper Launcher mirrors

René Chavan, Jean-Daniel Landis, Francisco Sanchez, Robert Bertizzolo

Four of the 16 ITER upper port plugs will be devoted to electron cyclotron resonance heating (ECRH) in order to control magnetohydrodynamic (MHD) instabilities [1,2]. In order to achieve the stabilisation of the neoclassical tearing modes (NTM) and sawtoot ...

Progress on the ITER Electron Cyclotron Heating and Current Drive Upper Launcher Steering Mirror Control System

Timothy Goodman, René Chavan, Federico Alberto Alfredo Felici, Jean-Daniel Landis, Frédéric Dolizy, Francisco Sanchez, Robert Bertizzolo

The ITER ECRH upper launcher (UL) uses a steering mechanism assembly (SMA) to steer the beams in the appropriate location for controlling magnetohydrodynamic (MILD) activity in the plasma (NTMs and sawtooth oscillations). ...

Progress on the ITER ECRH upper launcher steering mirror identification and control

René Chavan, Federico Alberto Alfredo Felici, Jean-Daniel Landis, Frédéric Dolizy, Francisco Sanchez, Robert Bertizzolo

The main objective of the ITER ECRH upper launcher (UL) is to control magnetohydrodynamic activity, in particular neoclassical tearing modes (NTMs), by driving several MW of EC Current near the q = 1, 3/2, 2 flux surfaces, where NTMs are expected to occur. ...
