On ion cyclotron current drive for sawtooth control (2006)

Eriksson, L. G., Johnson, T., Mayoral, M. L., Coda, S., Sauter, O., Buttery, R. J., ...

Experiments using ion cyclotron current drive (ICCD) to control sawteeth are presented. In particular, discharges demonstrating shortening of fast ion induced long sawteeth reported in (Eriksson et...

Sawtooth control in fusion plasmas (2005)

Graves, J. P., Angioni, C., Budny, R. V., Buttery, R. J., Coda, S., Eriksson, L. G., ...

Clear observations of early triggering of neo-classical tearing modes by sawteeth with long quiescent periods have motivated recent efforts to control, and in particular destabilize, sawteeth. One...

Studies of burning plasma physics in the Joint European Torus (2004)

Mayoral, M. L., Buttery, R., Jones, T. T. C., Kiptily, V., Sharapov, S., Mantsinen, M. J., ...

In burning plasma experiments, the very energetic alpha (alpha) particles resulting from a deuterium-tritium fusion reaction will be the dominant heating mechanism and will give rise to new physics...

Destabilization of Fast-Ion-Induced Long Sawteeth by Localized Current Drive in the JET Tokamak (2004)

Eriksson, L.G., Mueck, A., Sauter, O., Coda, S., Mantsinen, M.J., Mayoral, M.L., ...

In a tokamak fusion reactor the energetic alpha particles will transiently stabilize the magnetohydrodynamic activity causing sawtooth oscillations. The crash events terminating long sawtooth free...

Destabilization of fast-ion-induced long sawteeth by localized current drive in the JET tokamak (2004)

Eriksson, L. G., Mueck, A., Sauter, O., Coda, S., Mantsinen, M. J., Mayoral, M. L., ...

In a tokamak fusion reactor the energetic alpha particles will transiently stabilize the magnetohydrodynamic activity causing sawtooth oscillations. The crash events terminating long sawtooth free...

Overview of JET results (2003)

Pamela, J., Solano, E. R., Adams, J. M., Agarici, G., Agarici, M., Akhter, H., ...

Scientific and technical activities on JET focus on the issues likely to affect the ITER design and operation. Our understanding of the ITER reference mode of operation, the ELMy H-mode, has...

Control of sawteeth and triggering of NTMs with ion cyclotron resonance frequency waves in JET (2002)

Westerhof, E., Sauter, O., Mayoral, M. L., Howell, D. F., Mantsinen, M. J., Nave, M. F. F., ...

A new scenario to delay or prevent neoclassical tearing mode (NTM) onset is presented. By active sawtooth destabilization, short period and low amplitude sawteeth are generated, such that the...

Control of neoclassical tearing modes by sawtooth control (2002)

Sauter, O., Westerhof, E., Mayoral, M. L., Alper, B., Belo, P. A., Buttery, R. J., ...

The onset of a neoclassical tearing mode (NTM) depends on the existence of a large enough seed island. It is shown in the Joint European Torus that NTMs can be readily destabilized by long-period...

Analysis of ion cyclotron heating and current drive at omega approximate to 2 omega(cH) for sawtooth control in JET plasmas (2002)

Mantsinen, M. J., Angioni, C., Eriksson, L. G., Gondhalekar, A., Hellsten, T., Johnson, T., ...

Ion cyclotron heating and current drive at omega approximate to 2omega(cH) in JET deuterium plasmas with a hydrogen concentration n(H)/(n(D)+n(H)) in the range of 5-15% are analysed, comparing...

Sawtooth, Neo-Classical Tearing Mode and Error Field Studies in JET (2002)

T.C. Hender, O. Sauter, B. Alper, C. Angioni, M. Baar, M. Benedetti, ...

A range of ITER relevant plasma stability issues have been studied in the JET tokamak; these include the effects of fast particles on sawteeth, control of NTMs via sawteeth seeds, scaling of (2,1)...
