Development Of Advanced Gyrotrons In Europe

Stefano Alberti, Jean-Philippe Hogge, Ioannis Pagonakis, Konstantinos Avramidis

The German PMW project and the European EGYC consortium are driving gyrotron developments for the two major plasma fusion experiments in Europe using ECRH, Wendelstein W7-X at Greifswald and the international ITER at Cadarache. 1 MW CW, 140 GHz conventiona ...

Calculation of Stray Magnetic Field Effects on the Operation of the ITER Electron Cyclotron System

Stefano Alberti, Jean-Philippe Hogge, Ioannis Pagonakis, Fengping Li

in a multi-gyrotron system such as the one presently designed for the ITER ECH & ECCD system, stray magnetic fields can significantly alter the operational capabilities of the global system. A numerical study was carried out within the European Gyrotron Co ...

The European 2MW, 170GHz coaxial cavity gyrotron for ITER

Timothy Goodman, Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Laurie Porte, Damien Fasel, Albert Perez, Ioannis Pagonakis

In the reference ECH design, ITER requires a total of 20MW/CW power at 170GHz using gyrotrons with a unit power of 1MW. A higher power per unit (2MW/gyrotron) would result in a strong reduction of the cost of the whole ECRH system, and would also relax the ...

Recent evolution of the simulation tools for computer aided design of electron-optical systems for powerful gyrotrons

Jean-Philippe Hogge, Trach-Minh Tran

Computer aided design of powerful gyrotrons for electron cyclotron resonance heating and current drive of fusion plasmas requires adequate physical models and efficient software packages for analysis, comparison and optimization of their electron-optical s ...

2007

Electron cyclotron resonance heating (ECRH) has proven to be one of the most attractive heating schemes for stellarators. Therefore, ECRH was chosen to be the main heating method for the Wendelstein 7-X stellarator (W7-X) now under construction at IPP Grei ...

The need of durable and abundant energy sources for future ages stimulates the studies of thermonuclear energy sources, based on hot plasma confinement by magnetic fields. The most developed concept of hot plasma trap is the tokamak, where the plasma confi ...

EPFL2005

The transport of particles in magnetically confined plasmas is of great importance for the development of fusion energy. It will determine techniques for fuelling, for controlling impurity concentrations and for the removal of the alpha particles produced ...

Feasibility of a motional Stark effect system on the TCV tokamak

Henri Weisen, Markus Siegrist

This article presents a feasibility study for a motional Stark effect diagnostic on the TCV tokamak. A numerical simulation code has been used to identify the optimal port arrangement and geometrical layout. It predicts the expected measurement accuracy fo ...
