TCV divertor upgrade for alternative magnetic configurations

Ambrogio Fasoli, Holger Reimerdes, Basil Duval, Stefano Coda, Yves Martin, Pierluigi Bruzzone, Jean-Marc Moret, Stefano Alberti, Duccio Testa, Patrick Blanchard

The Swiss Plasma Center (SPC) is planning a divertor upgrade for the TCV tokamak. The upgrade aims at extending the research of conventional and alternative divertor configurations to operational scenarios and divertor regimes of greater relevance for a fu ...

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 ...

Upgrade of the TCV tokamak, first phase: Neutral beam heating system

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Timothy Goodman, Yves Martin, Stefano Alberti, René Chavan, Alexander Karpushov, Damien Fasel, Matthieu Toussaint

Experiments on TCV are designed to complement the work at large integrated tokamak facilities (such as JET) to provide a stepwise approach to extrapolation to ITER and DEMO in areas where medium-size tokamaks can often exploit their experimental capabiliti ...
