Transport-Reaction Systems: Higher-Dimensional Domains and a Qualitative Dichotomy

Benedikt Geiger

We study general linear transport-reaction systems on an arbitrary dimensional hypercube with periodic boundary conditions. Transport-reaction systems are often used to model the f…

Suppression of core turbulence by profile shaping in Wendelstein 7-X

A. v. Stechow, O. Grulke, Th. Wegner +23

In the Wendelstein 7-X magnetic confinement experiment, a reduction of turbulent density fluctuations as well as anomalous impurity diffusion is associated with a peaking of the pl…

Global scaling of the heat transport in fusion plasmas

Sara Moradi, Johan Anderson, Michele Romanelli +2

A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…

Validating the ASCOT modelling of NBI fast ions in Wendelstein 7-X stellarator

S. Äkäslompolo, P. Drewelow, Y. Gao +37

The first fast ion experiments in Wendelstein 7-X were performed in 2018. They are one of the first steps in demonstrating the optimised fast ion confinement of the stellarator. Th…

A fast acquisition rate system for charge exchange measurements at the plasma edge at the ASDEX Upgrade tokamak

Marco Cavedon, Thomas Pütterich, Eleonora Viezzer +5

In this work, a new type of high through-put Czerny-Turner spectrometer has been developed which allows to acquire multiple channels simultaneously with a repetition time on the or…

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…
