Tungsten erosion in the outer divertor of JET [PDF]

open access: yesJournal of Nuclear Materials, 2007
Erosion of tungsten in the outer JET divertor was determined with a set of tungsten coated divertor tiles during the 2001–2004 discharge campaign. The tungsten marker was strongly eroded, with the largest erosion at the outer strike point position, where more than 75% of the initial W disappeared. Strong erosion is also observed at the outer baffle and

Tungsten as a Structural Divertor Material [PDF]

open access: yesAdvances in Science and Technology, 2010
Refractory materials, in particular tungsten base materials are considered as primary candidates for structural high heat load applications in future nuclear fusion power plants. Promising helium-cooled divertor design outlines make use of their high heat conductivity and strength. The upper operating temperature limit is mainly defined by the onset of

Interpretive modeling of tungsten divertor leakage during experiments with neon gas seeding

open access: yesNuclear Fusion
Many existing and future tokamaks with tungsten divertors operate, or will operate, with low- Z impurity seeding, but the direct effect of these seeded impurities on tungsten Scrape-off-Layer (SOL) transport has not been explored in detail.

WEST full tungsten operation with an ITER grade divertor [PDF]

open access: yesNuclear Fusion
The mission of WEST (tungsten-W Environment in Steady-state Tokamak) is to explore long pulse operation in a full tungsten (W) environment for preparing next-step fusion devices (ITER and DEMO) with a focus on testing the ITER actively cooled W divertor ...

Impurity transport simulation in the peripheral plasma in the large helical device with tungsten closed helical divertor

open access: yesNuclear Materials and Energy, 2018
Long pulse plasma discharges in the Large Helical Device have been often interrupted by iron dust emission induced by electric arcing on the surface of the vacuum vessel.

Absolute optical calibration using a simple tungsten light bulb: Experiment [PDF]

open access: yes, 2003
Absolute spectral intensity calibration of optical detectors has always been difficult. Up to now it was only possible through the use of expensive sources, which are cross-calibrated against national standards.

Investigation of the impact of flux expansion on tungsten content and radiation in JET-ILW

open access: yesNuclear Materials and Energy, 2021
The present paper shows the results of the investigation about the effects of the flux-expansion variation at the inner strike point location on the tungsten content in the plasma core, and on the bulk radiation in JET-ILW.

In-situ TEM observation of the response of ultrafine- and nanocrystalline-grained tungsten to extreme irradiation environments [PDF]

open access: yes, 2014
The accumulation of defects, and in particular He bubbles, can have significant implications for the performance of materials exposed to the plasma in magnetic-confinement nuclear fusion reactors. Some of the most promising candidates for deployment into

A solid tungsten divertor for ASDEX Upgrade [PDF]

open access: yesPhysica Scripta, 2011
The conceptual design of a solid tungsten divertor for ASDEX Upgrade (AUG) is presented. The Div-III design is compatible with the existing divertor structure. It re-establishes the energy and heat receiving capability of a graphite divertor and overcomes the limitations of tungsten coatings.
