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…
Plasma response measurements of external magnetic perturbations using electron cyclotron emission and comparisons to 3D ideal MHD equilibrium
M. Willensdorfer, S. S. Denk, E. Strumberger +16
The plasma response from an external n = 2 magnetic perturbation field in ASDEX Upgrade has been measured using mainly electron cyclotron emission (ECE) diagnostics and a rigid rot…
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…
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…
Three dimensional boundary displacement due to stable ideal kink modes excited by external n=2 magnetic perturbations
M. Willensdorfer, E. Strumberger, W. Suttrop +15
In low-collisionality scenarios exhibiting mitigation of edge localized modes (ELMs), stable ideal kink modes at the edge are excited by externally applied magnetic perturbation (M…
Experimental conditions to suppress edge localised modes by magnetic perturbations in the ASDEX Upgrade tokamak
W. Suttrop, A. Kirk, V. Bobkov +9
Access conditions for full suppression of Edge Localised Modes (ELMs) by Magnetic Perturbations (MP) in low density high confinement mode (H-mode) plasmas are studied in the ASDEX…
