Magnetic confinement fusion - Plasma heating with millimetre waves

The need for an intense source of coherent, millimetre-wavelength radiation to heat a fusion plasma and control its instabilities represents a significant challenge in the development of the ITER experimental fusion reactor. This challenge may now have bee ...

Studies of Electron Transport and Current Diffusion in Switched ECCD experiments on TCV

Olivier Sauter, Timothy Goodman, Stefano Alberti, Roland Behn, Emiliano Fable, Costanza Zucca

The aim of the present work is to provide a better insight on the magnetic shear profile modification in the Switched ECCD experiments. Modelling of the plasma current density is carried on by the ASTRA transport code employed in both predictive and interp ...

Fast ion source and detector for investigating the interaction of turbulence with suprathermal ions in a low temperature toroidal plasma - art. no. 10F503

Yi Zhang, Ambrogio Fasoli, Ivo Furno, Benoît Labit, Mario Ludovico Podesta, Francesca Maria Poli, Gennady Plyushchev

A specific experimental apparatus consisting of an ion source and a detector for the investigation of the interaction between suprathermal ions and drift-wave turbulence is developed on the toroidal plasma experiment. Due to the low plasma temperature (sim ...

Process monitoring of alumina nanoparticle synthesis by inductively coupled RF thermal plasma

Jong-Won Shin

Since the first inductively coupled plasma (ICP) torch was developed in the 60's, RF thermal plasmas have found a variety of applications in material processing such as crystal growth, thermal spray coatings, spheroidization and vaporization of refractory ...

The influence of process parameters on precursor evaporation for alumina nanopowder synthesis in an inductively coupled rf thermal plasma

Christoph Hollenstein, Jong-Won Shin

The process parameters of an inductively coupled thermal plasma used for nanopowder synthesis are experimentally investigated using various plasma diagnostics and in situ powder monitoring methods. An enthalpy probe technique is applied to characterize the ...

Third-harmonic X-mode, real-time controlled top-launch ECW experiments on TCV Tokamak

Yves Martin, Stefano Alberti, Laurie Porte, Alexander Karpushov, Richard Pitts, Gilles Arnoux, Alessandro Bortolon

In the moderate magneticfield of TCV (1.5T), the recently installed X3 system (3 gyrotrons @118 GHz, 0.45 MW/each, 2s) broadens the operational space with the possibility of heating plasmas at high density, well above the cutoff density of the X2 system (X ...

Alfven mode stability and wave-particle interaction in the JET tokamak: prospects for scenario development and control schemes in burning plasma experiments

Ambrogio Fasoli, Duccio Testa

We have investigated the effect of different ion cyclotron resonance frequency (ICRF) heating schemes, of error field modes, of the plasma shape and edge magnetic shear, and of the ion delB drift direction on the stability of Alfven eigenmodes (AEs). The u ...

Simulations of global electrostatic microinstabilities in ASDEX Upgrade discharges

Olivier Sauter, Laurent Villard, Alberto Bottino

Electrostatic microinstabilities in ion internal barrier (ITB) and H-mode discharges of the ASDEX Upgrade tokamak [O. Gruber, R. Arslanbekov, C. Atanasiu , Nucl. Fusion 41, 1369 (2001)] have been investigated with a full radius gyrokinetic code. The code m ...

Tritium transport experiments on the JET tokamak

Henri Weisen

An overview is given of the experimental method, the analysis technique and the results for trace tritium experiments conducted on the JET tokamak in 2003. Observations associated with events such as sawtooth collapses, neo-classical tearing modes and edge ...

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 ...
