Evolution of SPI-induced disruptions in ASDEX Upgrade
P. Heinrich, G. Papp, S. Jachmich +23
Disruptions are a major concern for future fusion reactors based on the tokamak principle. To ensure machine protection, the thermal loads and vessel forces that arise during disru…
Integrated real-time supervisory management for off-normal-event handling and feedback control of tokamak plasmas
T. Vu, F. Felici, C. Galperti +7
For long-pulse tokamaks, one of the main challenges in control strategy is to simultaneously reach multiple control objectives and to robustly handle in real-time (RT) unexpected e…
Numerical study of tearing mode seeding in tokamak X-point plasma
Dmytro Meshcheriakov, Matthias Hoelzl, Valentin Igochine +11
A detailed understanding of island seeding is crucial to avoid (N)TMs and their negative consequences like confinement degradation and disruptions. In the present work, we investig…
Experimental investigation of the radial structure of energetic particle driven modes
L. Horvath, G. Papp, Ph. Lauber +8
Alfvén eigenmodes (AEs) and energetic particle modes (EPMs) are often excited by energetic particles (EPs) in tokamak plasmas. One of the main open questions concerning EP driven i…
Reducing systematic errors in time-frequency resolved mode number analysis
L. Horváth, P. Zs. Poloskei, G. Papp +3
The present paper describes the effect of magnetic pick-up coil transfer functions on mode number analysis in magnetically confined fusion plasmas. Magnetic probes mounted inside t…
Sawtooth control using electron cyclotron current drive in the presence of energetic particles in high performance ASDEX Upgrade plasmas
I T Chapman, V Igochine, M Maraschek +4
Sawtooth control using steerable electron cyclotron current drive (ECCD) has been demonstrated in ASDEX Upgrade plasmas with a significant population of energetic ions in the plasm…
Solitary magnetic perturbations at the ELM onset
RP Wenninger, H Zohm, JE Boom +19
Edge localised modes (ELMs) allow maintaining sufficient purity of tokamak H-mode plasmas and thus enable stationary H-mode. On the other hand in a future device ELMs may cause div…
Direct observation of current in type I ELM filaments on Asdex Upgrade
N. Vianello, V. Naulin, R. Schrittwieser +8
Magnetically confined plasmas are often subject to relaxation oscillations accompanied by large transport events. This is particularly the case for the high confinement regime of t…
Bayesian analysis of magnetic island dynamics
R. Preuss, M. Maraschek, H. Zohm +1
We examine a first order differential equation with respect to time coming up in the description of magnetic islands in magnetically confined plasmas. The free parameters of this e…
