A predictive formula for the H-mode electron separatrix density: Bridging regression and physics-based models across C-Mod, AUG and JET tokamaks
D. Silvagni, O. Grover, A. Stagni +27
The electron density at the separatrix () plays a central role in balancing energy confinement, detachment achievement, and ELM suppression in tokamaks, thereby…
Numerical study of tearing mode seeding in tokamak X-point plasma
Dmytro Meshcheriakov, Matthias Hoelzl, Valentin Igochine +11
A detailed understanding of island seeding is crucial to avoid (N)TMs and their negative consequences like confinement degradation and disruptions. In the present work, we investig…
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…
Plasma response measurements of external magnetic perturbations using electron cyclotron emission and comparisons to 3D ideal MHD equilibrium
M. Willensdorfer, S. S. Denk, E. Strumberger +16
The plasma response from an external n = 2 magnetic perturbation field in ASDEX Upgrade has been measured using mainly electron cyclotron emission (ECE) diagnostics and a rigid rot…
Solitary magnetic perturbations at the ELM onset
RP Wenninger, H Zohm, JE Boom +19
Edge localised modes (ELMs) allow maintaining sufficient purity of tokamak H-mode plasmas and thus enable stationary H-mode. On the other hand in a future device ELMs may cause div…
Bayesian analysis of magnetic island dynamics
R. Preuss, M. Maraschek, H. Zohm +1
We examine a first order differential equation with respect to time coming up in the description of magnetic islands in magnetically confined plasmas. The free parameters of this e…
