TL;DR: A review of the progress accomplished since the redaction of the first ITER Physics Basis (1999 Nucl Fusion 39 2137-664) in the field of energetic ion physics and its possible impact on burning plasma regimes is presented in this paper.
Journal ArticleDOI
Alfven eigenmode experiments in tokamaks and stellarators
Ambrogio Fasoli,D. N. Borba,C. Gormezano,R. F. Heeter,A. Jaun,J. Jacquinot,Wolfgang Kerner,Q.A. King,J.B. Lister,S. E. Sharapov,D.F.H. Start,Laurent Villard +11 more
TL;DR: In this paper, the balance between the drive and the background damping is investigated using active diagnostic systems to excite and measure the Alfven eigenmodes (AE) spectrum in terms of frequencies and damping rates.
Journal ArticleDOI

TL;DR: In this paper, the first experiments to drive Alfven eigenmodes (AEs) with antennas external to a tokamak plasma are presented, and a new class of weakly damped AEs has been identified experimentally.
Journal ArticleDOI
Prediction of Alfvén eigenmode dampings in the Joint European Torus
TL;DR: In this article, a gyrokinetic toroidal plasma model was used to reproduce the evolution of Alfven eigenmode (AE) dampings over a range of discharges, and strong stabilization occurs when the wave field gets localized radially by a rise in the edge magnetic shear, explaining why global AEs have never been detected in the Joint European Torus.
Journal ArticleDOI
Experimental test of damping models for n=1 toroidal Alfven eigenmodes in JET
D. Testa,D. Testa,Guoyong Fu,A. Jaun,Ambrogio Fasoli,Ambrogio Fasoli,Olivier Sauter,Jet-Efda Contributors +7 more
TL;DR: In this paper, the damping rate of the n = 1 toroidal Alfven eigenmodes (TAE) mode in Ohmic-heated JET plasmas has been measured and compared with the prediction of the kinetic NOVA-K code, which includes electron and ion Landau damping of the global shear Alfven wave field, collisional damping, and radiative damping.
