The in-vessel components of the experiment WENDELSTEIN 7-X [PDF]
Fusion Engineering and Design, 2009 Abstract The in-vessel components of the WENDELSTEIN 7-X stellarator consist of the divertor components and the wall protection with its internal cooling supply. The main components of the open divertor are the vertical and horizontal target plates which form the pumping gap, the cryo-vacuum pumps and the control coils.Stadler, R., Vorköper, A., Boscary, J., Cardella, A., Hurd, F., Li, C., Mendelevitch, B., Peacock, A., Pirsch, H. +8 moreopenaire +3 more sourcesNumerical studies of plasma edge in W7-X with 3D FINDIF code

Contributions to Plasma Physics, EarlyView.ABSTRACT
Experiments in the stellarator Wendelstein 7‐X indicate that particle drifts have a significant impact on the plasma in the scrape‐off layer. However, drift effects have been absent in the mean‐field transport codes such as EMC3‐Eirene. For this reason, we present the first steps towards a mean‐field model that incorporates drifts.
