Design and implementation of quasi-optical components for the upgrade of the TCV EC-system

Timothy Goodman, Stefano Alberti, Jean-Philippe Hogge, Laurie Porte, Matthieu Toussaint, Florian Ramseyer

The EC-system of the TCV tokamak is progressively being upgraded with the addition of two MW-class dual-frequency gyrotrons (84 and 126 GHz/2s/1MW). In order to connect the two gyrotrons to the existing low field side and top launchers, new waveguide routi ...

Thermal, electromagnetic and structural analysis of gas baffles for the TCV divertor upgrade

Basil Duval, Matthieu Toussaint, Jean-Marc Moret, Dario Vaccaro, Holger Reimerdes, Christian Gabriel Theiler

As part of an ongoing divertor upgrade of the TCV tokamak it is planned to add gas baffles to form a divertor chamber of variable closure. The baffles promise to increase the compression of neutral particles in the divertor and, thereby, extend the researc ...

High-efficiency, long-pulse operation of MW-level dual-frequency gyrotron, 84/126GHz, for the TCV Tokamak

Timothy Goodman, Stefano Alberti, Jean-Philippe Hogge, Damien Fasel, Matthieu Toussaint, Pierre Lavanchy, Ugo Siravo, Jérémy Genoud, Jérémie Dubray, Jonathan Sylvain Masur

The first unit of the dual-frequency gyrotron, 84-126GHz/lMW/2s, for the upgrade of the TCV ECH system has been delivered and is presently being commissioned. During a first phase, long-pulse operation (TRF>0.5s) has been achieved and powers in excess of 0 ...

V-band Doppler backscattering diagnostic in the TCV tokamak

Stefano Coda, Laurie Porte, Pierre Lavanchy, Matthieu Toussaint, Pedro Andres Molina Cabrera, Nicola Offeddu

A variable configuration V-band heterodyne Doppler back-scattering diagnostic has been recently made operational in the tokamak a configuration variable. This article describes the hardware setup options, flexible quasi-optical launcher antenna, data-analy ...

Improving spatial and spectral resolution of TCV Thomson scattering

Basil Duval, Patrick Blanchard, René Chavan, Joan Decker, Xavier Llobet, Yanis Andrebe, Matthieu Toussaint, Pierre Lavanchy, Philippe Marmillod, Robert Bertizzolo

The recently completed MST2 upgrade to the Thomson scattering (TS) system on TCV (Tokamak a Configuration Variable) at the Swiss Plasma Center aims to provide an enhanced spatial and spectral resolution while maintaining the high level of diagnostic flexib ...

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 ...

3D, LTCC-type, high-frequency magnetic sensors for the TCV Tokamak

Duccio Testa, Matthieu Toussaint, Gaël André Léon Farine, Thomas Maeder, Caroline Jacq, Adrien Aymeric Thibault Corne

High-frequency, 3D magnetic sensors have been designed and manufactured in-house for installation on the Tokamak a Configuration Variable (TCV). To optimize the in-vessel volume occupation, the sensors are based on combining the Low Temperature Co-fired Ce ...

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 ...
