Ambrogio Fasoli,C. Gormenzano,Herbert L Berk,Boris Breizman,Sergio Briguglio,D. S. Darrow,Nikolai Gorelenkov,W. W. Heidbrink,A. Jaun,Sergey Konovalov,Raffi Nazikian,J.-M. Noterdaeme,S. E. Sharapov,Kouji Shinohara,Duccio Testa,Kenji Tobita,Yasushi Todo,Gregorio Vlad,Fulvio Zonca +18 more
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
Universal Eigenmode in a Strongly Sheared Magnetic Field
L.D. Pearlstein,Herbert L Berk +1 more
TL;DR: In this paper, it was shown that in the presence of large shear, an unstable universal eigenmode exists and the criterion for the stabilization of this mode for long wavelengths was defined.
Journal ArticleDOI
The HAGIS self-consistent nonlinear wave-particle interaction model
S. D. Pinches,L. C. Appel,Jeff Candy,S. E. Sharapov,Herbert L Berk,D. N. Borba,Boris Breizman,T. C. Hender,Keith I. Hopcraft,G. T.A. Huysmans,Wolfgang Kerner +10 more
TL;DR: In this article, the problem of modeling the selfconsistent interaction of an energetic particle ensemble with a wave spectrum specific to magnetically confined plasmas in a torus is discussed.
Journal ArticleDOI
Theoretical Interpretation of Alfvén Cascades in Tokamaks with Nonmonotonic q Profiles
TL;DR: Alfv\'en spectra in a reversed-shear tokamak plasma with a population of energetic ions exhibit a quasiperiodic pattern of primarily upward frequency sweeping as mentioned in this paper.
Journal ArticleDOI
Spontaneous hole-clump pair creation in weakly unstable plasmas
TL;DR: In this article, a numerical simulation of a kinetic instability near threshold shows how a hole and clump spontaneously appear in the particle distribution function and support a pair of Bernstein, Greene, Kruskal (BGK) nonlinear waves that last much longer than the inverse linear damping rate while they are upshifting and downshifting in frequency.
