First step toward multi machine ELM energy scalings and extrapolations to SPARC and ITER
R. Perillo, A. Redl, T. Eich +14
It is shown that the ELM energy loss normalized by the plasma stored energy (ΔEELM/Wplasma) for high-density small/QCE ELM regimes scales inversely with the separatrix turbulence p…
First-Principles Explanation of the Drift Configuration Dependence of the Radial Electric Field and High-Confinement Access in Tokamaks
B. J. Frei, R. Bilato, O. Grover +6
The origin of the difference in the high-confinement (H-mode) power threshold between favorable and unfavorable drift configurations in tokamaks, experimentally linked to a deeper…
Quantitative 3D non-linear simulations of shattered pellet injection in ASDEX Upgrade using JOREK
W. Tang, M. Hoelzl, P. Heinrich +16
Shattered pellet injection (SPI) as primary mitigation method for major disruptions in ITER has a large parameter space available for optimization including the total amount of inj…
Complex structure of turbulence across the ASDEX Upgrade pedestal
L. A. Leppin, T. Görler, M. Cavedon +4
The theoretical investigation of relevant turbulent transport mechanisms in H-mode pedestals is a great scientific and numerical challenge. In this study, we address this challenge…
Probing non-linear MHD stability of the EDA H-mode in ASDEX Upgrade
A Cathey, M Hoelzl, L Gil +11
Regimes of operation in tokamaks that are devoid of large ELMs have to be better understood to extrapolate their applicability to reactor-relevant devices. This paper describes non…
Gyrokinetic investigation of the nonlinear interaction of Alfvén instabilities and energetic-particle driven geodesic acoustic modes
F. Vannini, A. Biancalani, A. Bottino +6
This paper presents a study of the interaction between Alfvén modes and zonal structures, considering a realistic ASDEX Upgrade equilibrium. The results of gyrokinetic simulations…
On the role of filaments in perpendicular heat transport at the Scrape-off Layer
D. Carralero, S. Artene, M. Bernert +9
In this work we carry out quantitative measurements of particle and heat transport associated to SOL filaments in a tokamak, and relate density shoulder formation to the advection…
Kinetic modelling of runaway electron generation in argon-induced disruptions in ASDEX Upgrade
K. Insulander Björk, G. Papp, O. Embreus +8
Massive material injection has been proposed as a way to mitigate the formation of a beam of relativistic runaway electrons that may result from a disruption in tokamak plasmas. In…
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…
Gyrokinetic investigation of the damping channels of Alfvén modes in ASDEX Upgrade
F. Vannini, A. Biancalani, A. Bottino +6
The linear destabilization and nonlinear saturation of energetic-particle driven Alfvénic instabilities in tokamaks strongly depend on the damping channels. In this work, the colli…
Linear gyrokinetic investigation of the geodesic acoustic modes in realistic tokamak configurations
I. Novikau, A. Biancalani, A. Bottino +7
Geodesic acoustic modes (GAMs) are studied by means of the gyrokinetic global particle-in-cell code ORB5. Linear electromagnetic simulations in the low electron beta limit have bee…
Adjoint Monte Carlo Simulation of Fusion Product Activation Probe Experiment in ASDEX Upgrade tokamak
Simppa Äkäslompolo, Georges Bonheure, Giovanni Tardini +1
The activation probe is a robust tool to measure flux of fusion products from a magnetically confined plasma. A carefully chosen solid sample is exposed to the flux, and the imping…
