TL;DR: The first fast ion experiments in Wendelstein 7-X were performed in 2018 as mentioned in this paper, where the fast ions were produced with a neutral beam injection (NBI) system and detected with infrared cameras (IR), a fast ion loss detector (FILD), fast ion charge exchange spectroscopy (FIDA), and post-mortem analysis of plasma facing components.

TL;DR: The implementation and verification of a HELIAS module into PROCESS is addressed, which includes: a plasma geometry model based on Fourier coefficients, a basic island divertor model, as well as a coil model which combines scaling aspects based on the Helias 5-B reactor design in combination with analytic inductance and field calculations.

TL;DR: In this article, the influence of a resonant magnetic perturbation (RMP) from the dynamic ergodic divertor (DED) in the m/n = 3/1 mode on argon impurity transport is studied at the tokamak TEXTOR.

TL;DR: In this paper, a dedicated magnetic configuration is presented and the limiter design for this early phase is explained, where the position of the main stellarator islands in this configuration is shifted radially outwards in order to have closed flux surfaces in front and in the shadow of a limiter for at least several centimeters.

TL;DR: In this paper, numerical calculations based on nonlinear two-fluid equations have been carried out to understand the sawtooth-like crashes of electron temperature observed in Wendelstein 7-X stellarator experiments with electron cyclotron current drive (ECCD) leads to non-monotonic radial profiles of the safety factor q with two q=1 surfaces in the plasma core region.
