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

Stefano Alberti, Damien Fasel, Timothy Goodman, Pierre-François Isoz, Pierre Lavanchy, Blaise Marlétaz, Jean-Philippe Hogge, Ugo Siravo, Jérémie Dubray, Jonathan Sylvain Masur, Miguel Filipe Silva Füglister, Matthieu Toussaint, Jérémy Genoud

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 ...

Beam duct for the 1 MW neutral beam injector on TCV

Basil Duval, Yves Martin, Stefano Coda, Alexander Karpushov, Frédéric Dolizy, Matthieu Toussaint, Roberto Maurizio

The 1MW power of the neutral beam injector (NBI) enters the plasma of the Tokamak a Configuration Variable (TCV) through a duct. The original beam propagation model predicted a maximal heat flux on the internal faces of the duct below 350 kW/m(2), leading ...

Nuclear technology aspects of ITER vessel-mounted diagnostics

Duccio Testa, Matthieu Toussaint

ITER has diagnostics with machine protection, basic and advanced control, and physics roles. Several are distributed on the inner and outer periphery of the vacuum vessel. They have reduced maintainability compared to diagnostics in ports. They also endure ...

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

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

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 ...
