Hollow toroidal rotation profiles in strongly electron heated H-mode plasmas in the ASDEX Upgrade tokamak
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…
Combing physics-based and data-driven predictions for quantitatively accurate models that extrapolate well; with application to DIII-D, AUG, and ITER tokamak fusion reactors
Joseph Abbate, Emiliano Fable, Giovanni Tardini +3
Methodologies for combining the accuracy of data-driven models with extrapolability of physics-based models are described and tested, for the task of building transport models of t…
Integrated modelling and multiscale gyrokinetic validation study of ETG turbulence in a JET hybrid H-mode scenario
J Citrin, S Maeyama, C Angioni +11
Previous studies with first-principle-based integrated modelling suggested that ETG turbulence may lead to an anti-GyroBohm isotope scaling in JET high-performance hybrid H-mode sc…
Electron runaway in ASDEX Upgrade experiments of varying core temperature
O. Linder, G. Papp, E. Fable +4
The formation of a substantial post-disruption runaway electron current in ASDEX Upgrade material injection experiments is determined by avalanche multiplication of a small seed po…
New high-confinement regime with fast ions in the core of fusion plasmas
A. Di Siena, R. Bilato, T. Görler +12
The key result of the present work is the theoretical prediction and observation of the formation of a new type of transport barrier in fusion plasmas, called F-ATB (fast ion-induc…
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…
Global gyrokinetic simulations of intrinsic rotation in ASDEX Upgrade Ohmic L-mode plasmas
W. A. Hornsby, C. Angioni, Z. X. Lu +6
Non-linear, radially global, turbulence simulations of ASDEX Upgrade (AUG) plasmas are performed and the nonlinear generated intrinsic flow shows agreement with the intrinsic flow…
Experimental observations and modelling of intrinsic rotation reversals in tokamaks
Y. Camenen, C. Angioni, A. Bortolon +8
The progress made in understanding spontaneous toroidal rotation reversals in tokamaks is reviewed and current ideas to solve this ten-year-old puzzle are explored. The paper inclu…
Validation of gyrokinetic modelling of light impurity transport including rotation in ASDEX Upgrade
F. J. Casson, R. M. McDermott, C. Angioni +9
Upgraded spectroscopic hardware and an improved impurity concentration calculation allow accurate determination of boron density in the ASDEX Upgrade tokamak. A database of boron m…
