Chapter 3: MHD stability, operational limits and disruptions

Timothy Goodman, Olivier Sauter, Hartmut Zohm

Progress in the area of MHD stability and disruptions, since the publication of the 1999 ITER Physics Basis document (1999 Nucl. Fusion 39 2137-2664), is reviewed. Recent theoretical and experimental research has made important advances in both understandi ...

IOP Publishing Ltd2007

Steady-state, fully bootstrap-sustained discharges in the TCV tokamak

Timothy Goodman, Olivier Sauter, Stefano Coda

2007

Electron Bernstein Wave Heating and Emission in the TCV Tokamak

Timothy Goodman, Antoine Pochelon, Stefano Coda, Laurie Porte, Loïc Curchod, Yann Camenen

Electron cyclotron resonance heating (ECRH) of high-density tokamak plasmas is limited because of reflections of the waves at so-called wave cutoffs. Electron Bernstein wave (EBW) heating (EBWH) via a double mode conversion process from ordinary (O)-mode, ...

2006

Shear modulation experiments with ECCD on TCV

Stefano Alberti, Roland Behn, Timothy Goodman, Petri Nikkola

Anomalous electron transport is determined by turbulence, which in turn is affected by magnetic shear. A novel application of electron cyclotron current drive (ECCD), aiming at localized shear modulation, has been applied on the TCV tokamak for experiments ...
