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 ...

Overview of the FTU results

Olivier Sauter, Basil Duval, Duccio Testa, Holger Reimerdes, Alexander Karpushov, Cristian Galperti, Gabriele Grosso, Doohyun Kim, Dávid Wágner, Lucia Isabel Federspiel, Jonathan Rossel, Donghyun Kim

Since the 2012 IAEA-FEC Conference, FTU operations have been largely devoted to runaway electrons generation and control, to the exploitation of the 140 GHz electron cyclotron (EC) system and to liquid metal limiter elements. Experiments on runaway electro ...

Suprathermal electron studies in Tokamak plasmas by means of diagnostic measurements and modeling

Josef Kamleitner

To achieve reactor-relevant conditions in a tokamak plasma, auxiliary heating systems are required and can be realized by waves injected in the plasma that heat ions or electrons under certain conditions. Electron cyclotron resonant heating (ECRH) is a ver ...

Experiments on magneto-hydrodynamics instabilities with ECH/ECCD in FTU using a minimal real-time control system

Cristian Galperti

Experiments on real time control of magneto-hydrodynamic (MHD) instabilities using injection of electron cyclotron waves (ECW) are being performed with a control system based on only three real time key items: an equilibrium estimator based on a statistica ...

Stability of Tokamak and RFP Plasmas with an Extended Region of Low Magnetic Shear

Daniele Brunetti

It has been observed experimentally that magnetically confined plasmas, characterised by the safety factor q with a small or slightly inverted magnetic shear, have good confinement properties. Such plasmas typically have no internal transport barrier, oper ...

Bifurcated Helical Core Equilibrium States in Tokamaks

Olivier Sauter, Basil Duval, Stefano Coda, Jonathan Graves, Wilfred Anthony Cooper, Holger Reimerdes, Benoît Labit, Antoine Pochelon, David Pfefferlé, Federico David Halpern, Daniele Brunetti, Jonathan Rossel, Mattia Albergante

Tokamaks with weak to moderate reversed central shear in which the minimum rotational transform

q_{min}

is in the neighbourhood of unity can trigger bifurcated MagnetoHydrodynamic (MHD) equilibrium states, one of which is similar to a saturated ideal ...

Equilibrium and stability in a heliotron with anisotropic hot particle slowing-down distribution

Jonathan Graves, Wilfred Anthony Cooper

The equilibrium and linear fluid Magnetohydrodynamic (MHD) stability in an inward-shifted large helical device heliotron configuration are investigated with the 3D ANIMEC and TERPSICHORE codes, respectively. A modified slowing-down distribution function is ...

MHD equilibrium and stability of tokamaks and RFP systems with 3D helical cores

Olivier Sauter, Jonathan Graves, Wilfred Anthony Cooper

Bifurcated magnetohydrodynamic (MHD) equilibrium states are computed for ITER hybrid scenario and RFX-mod SHAx configurations with very flat or reversed core magnetic shear conditions. In the ITER studies, the minimum inverse rotational transform qmin is n ...

Pedestal Characteristics and MHD Stability of H-Mode Plasmas in TCV

Andreas Pitzschke

The tokamak à configuration variable (TCV) is unique in its ability to create a variety of plasma shapes and to heat the electron population in high density regimes using microwave power at the third harmonic of the electron cyclotron frequency. In the fra ...
