Representation and modeling of charged particle distributions in tokamaks
Andreas Bierwage, Michael Fitzgerald, Philipp Lauber +3
Experimental diagnostics, analysis tools and simulations represent particle distributions in various forms and coordinates. Algorithms to manage these data are needed on platforms…
Energy-selective confinement of fusion-born alpha particles during internal relaxations in a tokamak plasma
Andreas Bierwage, Kouji Shinohara, Yevgen Kazakov +9
Long-pulse operation of a self-sustained fusion reactor using toroidal magnetic containment requires control over the content of alpha particles produced by D-T fusion reactions. O…
Mode structure symmetry breaking of reversed shear Alfvén eigenmodes and its impact on the generation of parallel velocity asymmetries in energetic particle distribution
Guo Meng, Philipp Lauber, Xin Wang +1
In this work, the gyrokinetic eigenvalue code LIGKA, the drift-kinetic/MHD hybrid code HMGC and the gyrokinetic full-f code TRIMEG-GKX are employed to study the mode structure deta…
Numerics and computation in gyrokinetic simulations of electromagnetic turbulence with global particle-in-cell codes
Alexey Mishchenko, Alessandro Biancalani, Alberto Bottino +7
Electromagnetic turbulence is addressed in tokamak and stellarator plasmas with the global gyrokinetic particle-in-cell codes ORB5 [E. Lanti et al, Comp. Phys. Comm, vol. 251, 1070…
Gyrokinetic investigation of the nonlinear interaction of Alfvén instabilities and energetic-particle driven geodesic acoustic modes
F. Vannini, A. Biancalani, A. Bottino +6
This paper presents a study of the interaction between Alfvén modes and zonal structures, considering a realistic ASDEX Upgrade equilibrium. The results of gyrokinetic simulations…
Effects of anisotropic energetic particles on zonal flow residual level
Zhixin Lu, Markus Weiland, Philipp Lauber +3
In tokamak plasmas, the interaction among the micro-turbulence, zonal flows (ZFs) and energetic particles (EPs) can affect the turbulence saturation level and the consequent confin…
