Construction and analysis of guiding center distributions for tokamak plasmas with ambient radial electric field
Andreas Bierwage, Philipp Lauber, Noriyoshi Nakajima +8
The contribution of a time-independent toroidally-symmetric radial electric field is implemented in VisualStart [Comp. Phys. Comm. 275 (2022) 108305; arXiv:2111.08224], a cod…
Saturation of fishbone instability through zonal flows driven by energetic particle transport in tokamak plasmas
G. Brochard, C. Liu, X. Wei +17
Gyrokinetic and kinetic-MHD simulations are performed for the fishbone instability in the DIII-D discharge #178631, chosen for validation of first-principles simulations to predict…
Saturation of fishbone instability by self-generated zonal flows in tokamak plasmas
G. Brochard, C. Liu, X. Wei +13
Gyrokinetic simulations of the fishbone instability in DIII-D tokamak plasmas find that self-generated zonal flows can dominate the nonlinear saturation by preventing coherent stru…

Explosive Ballooning Flux Tubes in Tokamaks
C J Ham, S C Cowley, G Brochard +1
Tokamak stability to, potentially explosive, `ballooning' displacements of elliptical magnetic flux tubes is examined in large aspect ratio equilibrium. Above a critical pressure g…
