Experiences with a solid tungsten divertor in ASDEX Upgrade
Nuclear Materials and Energy, 2017 In 2013 a redesigned solid tungsten divertor, Div-III, was installed in ASDEX Upgrade. In two experimental campaigns more than 2700 plasma discharges with up to 10s duration, 110MJ plasma heating, and reaching a Psep/R of 10MW/m were conducted.

Physics basis for the first ITER tungsten divertor
Nuclear Materials and Energy, 2019 On the eve of component procurement, this paper discusses the present physics basis for the first ITER tungsten (W) divertor, beginning with a reminder of the key elements defining the overall design, and outlining relevant aspects of the Research Plan accompanying the new “staged approach” to ITER nuclear operations which fixes the overall divertor ...

On the prediction and monitoring of tungsten prompt redeposition in tokamak divertors
Nuclear Materials and Energy, 2021 As net erosion of tungsten plasma-facing components in tokamak divertors is strongly reduced by tungsten prompt redeposition, predicting and monitoring tungsten prompt redeposition is crucial to estimate the lifetime of tungsten PFCs and the source of ...

Nuclear Materials and Energy, 2022 The new SAS-VW divertor in DIII-D has tungsten-coated components to enable the study of tungsten erosion and leakage from a closed, slot-like divertor. A proposed method of actively managing the tungsten impurities is to inject low-Z impurities, such as ...

Tungsten erosion and redeposition in the all-tungsten divertor of ASDEX Upgrade [PDF]
Physica Scripta, 2009 Net erosion and deposition of tungsten (W) in the ASDEX Upgrade divertor were determined after the 2007 campaign by using thin W marker stripes. ASDEX Upgrade had full-W plasma-facing components during this campaign. The inner divertor and the roof baffle were net W deposition areas with a maximum deposition of about 1×1018 W-atoms cm-2 in the private ...
