Study of ion-to-electron temperature ratio at the edge of Wendelstein 7-X using a fast swept ball-pen probe [PDF]

In the Wendelstein 7-X (W7-X) stellarator, a ball-pen probe (BPP) has been routinely employed to measure T$_i$ in the island scrape-off layer (SOL) across large parts of the recent 2024/2025 campaigns.

Impact of spatially varying transport coefficients in EMC3-Eirene simulations of W7-X and assessment of drifts

Nuclear Fusion
Modelling the scrape-off layer of a stellarator is challenging due to the complex magnetic 3D geometry. The here presented study analyses simulations of the scrape-off layer (SOL) of the stellarator Wendelstein 7-X (W7-X) using spatially varying ...
