Nonlinear dynamics of the fishbone-induced alpha transport on ITER
G. Brochard, R. Dumont, H. Lütjens +3
The fishbone-induced transport of alpha particles is computed for the ITER 15 MA baseline scenario, using the nonlinear hybrid Kinetic-MHD code XTOR-K. Two limit cases have been st…
En route to realistic modeling of the kinetic-MHD interaction between macroscopic modes and fast particles induced by neutral beam injection in tokamaks
F. Orain, G. Brochard, T. Nicolas +4
A new model of fast ion source induced by Neutral Beam Injection (NBI) in tokamaks has been implemented in the hybrid kinetic-magnetohydrodynamic code XTOR-K. This source, combined…
Linear stability of the ITER 15 MA scenario against the alpha fishbone
G. Brochard, R. Dumont, H. Lütjens +1
The stability of the alpha-fishbone kinetic-MHD mode on the ITER 15 MA baseline scenario \cite{ITERB} is analyzed using the nonlinear hybrid Kinetic-MHD code XTOR-K. Quanti…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
A new ICRF scenario for bulk ion heating in D-T plasmas: How to utilize intrinsic impurities in fusion devices in our favour
Y. O. Kazakov, J. Ongena, D. Van Eester +5
A fusion reactor requires plasma pre-heating before the rate of deuterium-tritium fusion reactions becomes significant. In ITER, radiofrequency (RF) heating of 3He ions, additional…
Recent progress on lower hybrid current drive and implications for ITER
Julien Hillairet, A. Ekedahl, M. Goniche +23
The sustainment of steady-state plasmas in tokamaks requires efficient current drive systems. Lower Hybrid Current Drive (LHCD) is currently the most efficient method to generate a…
Chaotic motion of charged particles in toroidal magnetic configurations
Benjamin Cambon, Xavier Leoncini, Michel Vittot +2
We study the motion of a charged particle in a tokamak magnetic field and discuss its chaotic nature. Contrary to most of recent studies, we do not make any assumption on any const…
Ion temperature profile stiffness: non-linear gyrokinetic simulations and comparison with experiment
J. Citrin, F. Jenko, P. Mantica +9
Recent experimental observations at JET show evidence of reduced ion temperature profile stiffness, hypothesised to be due to concomitant low magnetic shear (s) and significant tor…
Theory of Synergy between Electron Cyclotron and Lower Hybrid Waves
R. J. Dumont, G. Giruzzi
A theoretical study of the improvement of the Electron Cyclotron Current Drive (ECCD) efficiency in regimes where most of the current is driven by Lower Hybrid (LH) waves is presen…
