Power requirements for electron cyclotron current drive and ion cyclotron resonance heating for sawtooth control in ITER

Olivier Sauter, Stefano Coda, Timothy Goodman, Jonathan Graves, Costanza Zucca, Martin Jucker, Otto Asunta

13 MW of electron cyclotron current drive (ECCD) power deposited inside the q = 1 surface is likely to reduce the sawtooth period in ITER baseline scenario below the level empirically predicted to trigger neoclassical tearing modes (NTMs). However, since t ...

Overview of recent and current research on the TCV tokamak

Stefano Coda

Through a diverse research programme, the Tokamak a Configuration Variable (TCV) addresses physics issues and develops tools for ITER and for the longer term goals of nuclear fusion, relying especially on its extreme plasma shaping and electron cyclotron r ...

Demonstration of sawtooth period locking with power modulation in TCV plasmas

Olivier Sauter, Timothy Goodman, Federico Alberto Alfredo Felici

Corroborating evidence is presented that the sawtooth period can follow the modulation frequency of an externally applied high power electron cyclotron wave source. Precise, fast and robust open loop control of the sawtooth period with a continuously chang ...

Integrated real-time control of MHD instabilities using multi-beam ECRH/ECCD systems on TCV

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Federico Alberto Alfredo Felici, Jonathan Rossel

Simultaneous real-time control of multiple MHD instabilities is experimentally demonstrated in the TCV tokamak. Multiple sources of EC heating and current drive, injected through real-time controlled launchers, are used to stabilize 3/2 and 2/1 neoclassica ...
