Magnetic turnstiles in nonresonant stellarator divertor

Island divertor experiments on the Wendelstein 7-AS stellarator

A promising new operational regime on the Wendelstein stellarator W7-AS has been discovered, fulfilling the conditions of optimal core behavior in combination with edge parameters suitable for successful divertor scenarios. This regime, the high density H-mode (HDH), displays no systematically evident mode activity, and is edge localized mode (ELM)-free. It is extant above a power-dependent thr...

Porphyrin based molecular turnstiles.

Molecular turnstiles, based on a hinge composed of a Sn-porphyrin bearing coordinating sites at the meso positions and a handle, equipped with a tridentate coordinating pole or its Pd(ii) complex, connected to the porphyrin through Sn-O bonds, offering open (free rotation of the handle around the hinge) and close states (blockage of rotation through binding of Pd(ii)) were designed, prepared an...

The lmpact of the New lsland Divertor on the Plasma Performance in the W 7 - AS Stellarator

W7-AS has recently been equipped with ten open divertor modules in order to experimentally evaluate this exhaust concept in view of future application to W7-X. The new divertor enables access to a new NBl-heated, very high density (up to n" = 3.5x1020 m-3) operating regime with promising confinement properties. The energy confinement time increases steeply with density. In contrast, the particl...
