Self-consistent modeling of runaway electron generation in massive gas injection scenarios in ASDEX Upgrade
O. Linder, E. Fable, F. Jenko +4
We present the first successful simulation of a induced disruption in ASDEX Upgrade from massive material injection (MMI) up to established runaway electron (RE) beam, thus coverin…
Flux-driven integrated modelling of main ion pressure and trace tungsten transport in ASDEX Upgrade
O. Linder, J. Citrin, G. M. D. Hogeweij +9
Neoclassical and turbulent heavy impurity transport in tokamak core plasmas are determined by main ion temperature, density and toroidal rotation profiles. Thus, in order to unders…

C. F. B. Zimmermann, R. M. McDermott, C. Angioni +8
This work investigates toroidal momentum transport in type-I ELMy H-mode plasmas in the ASDEX Upgrade tokamak, focusing on the formation of hollow rotation profiles under strong el…
Flux pumping and bifurcated relaxations of helical core in 3D magnetohydrodynamic modelling of ASDEX Upgrade plasmas
H. Zhang, M. Hoelzl, I. Krebs +12
Flux pumping was achieved in recent hybrid scenario experiments in the ASDEX Upgrade (AUG) tokamak, which is characterized by a sawtooth-free helical quiescent state and the anomal…
Global gyrokinetic simulations of intrinsic rotation in ASDEX Upgrade Ohmic L-mode plasmas
W. A. Hornsby, C. Angioni, Z. X. Lu +6
