The basic design of a reliable and robust glow discharge cleaning (GDC) system for Wendelstein 7-X is presented. Preliminary experiments at the DEMO cryostat, a full size prototype sector of W7-X, result in conclusions about the operating range, powe

The research on divertors for stellarators is at the beginning. Extensive studies are being prepared on large helical device (LHD) and W7-X. W7-AS is now being operated with an open island divertor (ID) which serves as a test bed for the W7-X diverte

The WENDELSTEIN 7-X stellarator will be capable of running pulses of up to 30 min duration. The control system of W7-X will support all discharge scenarios compatible with this capability, i.e. short pulses with arbitrary intervals, steady state disc

WENDELSTEIN 7-X (W7-X) shall confirm the favourable plasma properties and the high density and beta limits of the helical advanced stellarator and demonstrate steady-state operation. The magnetic configuration of W7-X is characterized by a set of 50

The new island divertor in W7-AS enables quasi steady-state operation with NBI at very high density including scenarios with stable detachment from the targets. Experiments with reversed B-field indicate that the interaction zones on the targets are

Stellarators have the intrinsic property of steady state operation. However, on present-day stellarators the pulse length is usually not only limited due to technical reasons, but also by physical problems. Lack of density control and a subsequent ra
