Homogenous power distribution along gyrotron collector walls

Stefano Alberti, Jean-Philippe Hogge, Damien Fasel, Ugo Siravo, Jérémie Dubray, Miguel Filipe Silva Füglister, Pierre-François Isoz

EC RF power sources will play a major role in the future operation of large scale tokamaks (ITER, DEMO). A 1MW/170GHz gyrotron is the standard RF power unit considered for ITER. Even though the efficiency of such devices has been significantly increased th ...

New capabilities of the incoherent Thomson scattering diagnostics in the TCV tokamak: divertor and real-time measurements

Basil Duval, Patrick Blanchard, Federico Alberto Alfredo Felici, Xavier Llobet, Joan Decker, Yanis Andrebe, Pierre Lavanchy, Cristian Galperti, Philippe Marmillod, Blaise Marlétaz

This work reports developments of the incoherent TS diagnostic capabilities in the Tokamak a Configuration Variable (TCV). Their goals are to (i) diagnose the TCV divertor region, and (ii) provide Te and ne profiles of the plasma bulk in real-time. These t ...

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 ...

Thomson scattering measurements in the divertor region of the TCV Tokamak plasmas

Basil Duval, Ivo Furno, Patrick Blanchard, Xavier Llobet, Joan Decker, Yanis Andrebe, Pierre Lavanchy, Riccardo Agnello, Steve Couturier, Severino Antonioni

In order to better study conventional and alternative divertor configurations, the TCV Tokamak was recently upgraded. In-vessel graphite baffles were installed in the TCV chamber to delimit a separate divertor chamber from the core that required enhanced d ...

Recent electron cyclotron emission results on TCV

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Patrick Blanchard, Laurie Porte, Xavier Llobet, Christian Schlatter, Henri Weisen, Emiliano Fable

Electron cyclotron emission (ECE) diagnostics on Tokamak a Configuration Variable (TCV) allow study of the electron temperature evolution in time with good spatial and temporal resolution at the high field side and low field side at various lines of sight. ...

Safety factor profile requirements for electron ITB formation in TCV

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge

On the Tokamak a Configuration Variable (TCV), electron internal transport barriers (eITBs) can be formed during a gradual evolution from a centrally peaked to a hollow current profile while all external actuators are held constant. The formation occurs ra ...
