Thornton,P. de Vries,Efda Jet Contributors +30 more
TL;DR: In this paper, a brief overview on the disruption loads and mitigation strategies for ITER and the physics basis which is continuously refined through the current disruption R&D programs is discussed.
Journal ArticleDOI
Feedback and rotational stabilization of resistive wall modes in ITER
Yueqiang Liu,Anders Bondeson,Ming-Sheng Chu,J.-Y. Favez,Y. Gribov,Mikhail Gryaznevich,T. C. Hender,D. F. Howell,R.J. La Haye,J.B. Lister,P. de Vries,Efda Jet Contributors +11 more
TL;DR: In this paper, the damping effect on resistive wall modes (RWM) in rotating plasmas has been investigated using the stability code MARS-F in order to study damping effects on RWM.
Journal ArticleDOI
JET experiments to assess the clamping of the fast ion energy distribution during ICRF heating due to finite Larmor radius effects
A. Salmi,Mervi Mantsinen,P. Beaumont,P. de Vries,L.-G. Eriksson,C. Gowers,Per Helander,Martin Laxåback,J.-M. Noterdaeme,D. Testa,Efda Jet Contributors +10 more
TL;DR: In this paper, the role of finite Larmor radius (FLR) effects on the resonant ion distribution function was investigated on the JET tokamak with 2nd harmonic ion cyclotron resonance heating (ICRH) of hydrogen in deuterium plasmas.
Journal ArticleDOI
NBI torque in the presence of magnetic field ripple : experiments and modelling for JET
A. Salmi,T. Tala,G. Corrigan,Carine Giroud,Jorge Ferreira,J. Lönnroth,P. Mantica,Vassili Parail,M. Tsalas,T. W. Versloot,P. de Vries,K-D. Zastrow,Efda Jet Contributors +12 more
TL;DR: In this paper, the authors present the first experimental validation of torque profile calculation from neutral beam injection (NBI) under toroidal field ripple using discharges from a dedicated experimental session on JET where neutral beam modulation technique is used together with time-dependent torque calculations from ASCOT code for making the benchmark.
Journal ArticleDOI
Fast ion distributions driven by polychromatic ICRF waves on JET
M. J. Mantsinen,V. G. Kiptily,Martin Laxåback,A. Salmi,Yu.F. Baranov,R. Barnsley,P. Beaumont,S. Conroy,P. de Vries,C. Giroud,C. Gowers,Torbjörn Hellsten,L. C. Ingesson,Thomas Johnson,H. Leggate,M.-L. Mayoral,I. Monakhov,Jean-Marie Noterdaeme,Jean-Marie Noterdaeme,S. Podda,S. E. Sharapov,Angelo A. Tuccillo,D. Van Eester,Efda Jet Contributors +23 more
TL;DR: Polychromatic ICRF has the advantage of producing smaller-amplitude and shorter-period sawteeth, consistent with a lower fast ion pressure inside the q = 1 surface, and higher ion to electron temperature ratios as discussed by the authors.
