Meaning of the splitting process for the transition to self-sustained turbulence in a magnetized cylindrical plasma
Stefan Knauer, Chanho Moon, Thomas Schleyerbach +4
When turbulent structures split more frequently before they decay, persistent turbulence forms in neutral fluid shear flows. Whether this concept can be extended to linear magnetiz…
I-mode pedestal relaxation events at ASDEX Upgrade
D. Silvagni, T. Eich, T. Happel +16
The I-mode confinement regime can feature small edge temperature drops that can lead to an increase in the energy deposited onto the divertor targets. In this work, we show that th…
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…
Nonlinear dynamics of energetic-particle driven geodesic acoustic modes in ASDEX Upgrade
I. Novikau, A. Biancalani, A. Bottino +9
Turbulence in tokamaks generates radially sheared zonal flows. Their oscillatory counterparts, geodesic acoustic modes (GAMs), appear due to the action of the magnetic field curvat…
Global turbulence simulations of the tokamak edge region with GRILLIX
A. Stegmeir, A. Ross, T. Body +8
Turbulent dynamics in the scrape-off layer (SOL) of magnetic fusion devices is intermittent with large fluctuations in density and pressure. Therefore, a model is required that all…
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…
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…
