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…
A quasi-continuous exhaust scenario for a fusion reactor: the renaissance of small edge localized modes
G. F. Harrer, M. Faitsch, L. Radovanovic +13
Tokamak operational regimes with small edge localized modes (ELMs) could be a solution to the problem of large transient heat loads in future fusion reactors because they provide q…
Non-linear extended MHD simulations of type-I edge localised mode cycles in ASDEX Upgrade and their underlying triggering mechanism
Andres Cathey, M. Hoelzl, K. Lackner +9
A triggering mechanism responsible for the explosive onset of edge localised modes (ELMs) in fusion plasmas is identified by performing, for the first time, non-linear magnetohydro…
Recent progress towards a quantitative description of filamentary SOL transport
D. Carralero, M. Siccinio, M. Komm +22
A summary of recent results on filamentary transport, mostly obtained in the ASDEX-Upgrade tokamak (AUG), is presented and discussed in an attempt to produce a coherent picture of…
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…
Identity of the JET M-mode and the ASDEX Upgrade I-phase phenomena
D. I. Réfy, E. R. Solano, N. Vianello +11
An H-mode plasma state free of edge-localized mode (ELM), close to the L-H transition with clear density and temperature pedestal has been observed both at the Joint European Torus…
Pellet refuelling of particle loss due to ELM mitigation with RMPs in the ASDEX Upgrade tokamak at low collisionality
M Valovič, P T Lang, A Kirk +17
The complete refuelling of the plasma density loss (pump-out) caused by mitigation of Edge Localised Modes (ELMs) is demonstrated on the ASDEX Upgrade tokamak. The plasma is refuel…
Experimental validation of a filament transport model in turbulent magnetized plasmas
D. Carralero, P. Manz, L. Aho-Mantila +9
In a wide variety of natural and laboratory magnetized plasmas, filaments appear as a result of interchange instability. These convective structures substantially enhance transport…
An experimental investigation on the high density transition of the Scrape-off Layer transport in ASDEX Upgrade
D. Carralero, G. Birkenmeier, H. W. Müller +8
A multidiagnostic approach, utilizing Langmuir probes in the midplane, X-point and divertor walls, along with Lithium beam and infrared measurements is employed to evaluate the evo…
