Third harmonic X-mode absorption in a top-launch configuration on the TCV tokamak

Stefano Alberti, Jean-Philippe Hogge, Laurie Porte, Gilles Arnoux

In addition to the second harmonic X-mode (X2) electron cyclotron heating (ECH), the TCV ECH system has been completed with three 450 kW gyrotrons operating at the frequency of 118 GHz for third harmonic X-mode (X3) in a top-launch configuration. In the re ...

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 ...

Third-harmonic, top-launch, ECRH experiments on TCV tokamak

Yves Martin, Stefano Alberti, Jean-Philippe Hogge, Laurie Porte, Philippe Marmillod, Gilles Arnoux, Blaise Marlétaz

In the moderate magnetic field of TCV (1.5 T), the recently installed X3 system (3 gyrotrons, 118 GHz, 0.45 MW each, 2 s) broadens the operational space with the possibility of heating plasmas at high density, well above the cutoff density of the X2 system ...
