The basic physics of the processes playing the most important role in divertor plasma
detachment is reviewed. The models used in the two-dimensional edge plasma transport …

A new small angle slot (SAS) divertor concept has been developed to enhance neutral
cooling across the divertor target by coupling a closed slot structure with appropriate target …

The island divertor concept is an innovative and promising idea to handle heat and particle
exhaust in stellarators. At the Wendelstein 7-X (W7-X) stellarator, this divertor concept plays …

Detached divertor plasmas feature strong radial and parallel gradients of density,
temperature, electric fields and flow over the divertor volume and therefore, sampling the …

A one dimensional, absolutely calibrated pinhole camera system was installed on the DIII-D
tokamak to measure edge Lyman-alpha (Ly-α) emission from hydrogen isotopes, which can …

To demonstrate the performance of tungsten (W) as the divertor target material and to solve
the power handling problem during high power long-pulse discharge, the upgrade of EAST …

DIII-D plasmas are compared for two upper divertor configurations: with the outer strike point
on the small angle slot (SAS) divertor target and with the outer strike point on the horizontal …

Magnetohydrodynamic (MHD) instabilities are widely observed during tokamak plasma
operation. Magnetic diagnostics provide important information which supports the …

Scrape-off layer plasma simulation modeling has been carried out to assess the effect of
tightly closing the lower divertor in DIII-D, which at present is almost fully open, on the …

Edge plasma code SOLPS modeling has been used to assess the effects of divertor
detachment vs attachment and closure vs openness on the main scrape-off layer (SOL) …
