How well can VMEC predict the initial saturation of external kink modes in near circular tokamaks and stellarators?
Rohan Ramasamy, Matthias Hoelzl, Sophia Henneberg +3
The equilibrium code, VMEC, is used to study external kinks in low tokamaks and stellarators. The applicability of the code when modelling nonlinear MHD effects is explor…
JOREK3D: An extension of the JOREK nonlinear MHD code to stellarators
Nikita Nikulsin, Rohan Ramasamy, Matthias Hoelzl +4
Although the basic concept of a stellarator was known since the early days of fusion research, advances in computational technology have enabled the modelling of increasingly compl…
The JOREK non-linear extended MHD code and applications to large-scale instabilities and their control in magnetically confined fusion plasmas
M Hoelzl, GTA Huijsmans, SJP Pamela +50
JOREK is a massively parallel fully implicit non-linear extended MHD code for realistic tokamak X-point plasmas. It has become a widely used versatile code for studying large-scale…
Magnetic flux pumping in 3D nonlinear magnetohydrodynamic simulations
I. Krebs, S. C. Jardin, S. Günter +4
A self-regulating magnetic flux pumping mechanism in tokamaks that maintains the core safety factor at , thus preventing sawteeth, is analyzed in nonlinear 3D magnetohy…
Field-line localized destabilization of ballooning modes in 3D tokamaks
M. Willensdorfer, T. B. Cote, C. C. Hegna +10
Field-line localized ballooning modes have been observed at the edge of high confinement mode plasmas in ASDEX Upgrade with rotating 3D perturbations induced by an externally appli…
Three dimensional boundary displacement due to stable ideal kink modes excited by external n=2 magnetic perturbations
M. Willensdorfer, E. Strumberger, W. Suttrop +15
In low-collisionality scenarios exhibiting mitigation of edge localized modes (ELMs), stable ideal kink modes at the edge are excited by externally applied magnetic perturbation (M…
