Erosion estimates for the divertor and main wall components from STEP

Nuclear Fusion, 2023
The tungsten erosion within Spherical Tokamak for Energy Production (STEP) assuming tungsten main wall and tungsten divertor has been estimated with ERO at the inner and outer divertor, at the inner and outer midplane and at the outboard baffle entrance.

Use of tungsten material for the ITER divertor

Nuclear Materials and Energy, 2016
AbstractSince the ITER divertor design includes tungsten monoblocks in the vertical target where heat loads are maximal, the design to protect leading edges as well as technology R&D for high performance armor-heat sink joint were necessary to be implemented.

Tungsten foil laminate for structural divertor applications – Joining of tungsten foils

Journal of Nuclear Materials, 2013
Abstract This paper is the fourth in our series on tungsten laminates. The aim of this paper is to discuss laminate synthesis, meaning the joining of tungsten foils. It is obvious that the properties of the tungsten laminate strongly depend on the combination of (i) interlayer and (ii) joining technology, as this combination defines (i) the condition

R&D of a strain monitoring system for the EAST tungsten divertor

Nuclear Materials and Energy, 2019
The tungsten divertor of the Experimental Advanced Superconducting Tokamak (EAST) device operates at varying temperatures and strong electromagnetic fields during plasma operation. In order to monitor the thermomechanical and electromagnetic responses of

Absolute optical calibrations using a simple tungsten bulb: Theory [PDF]

, 2001
The absolute spectral intensity calibration of optical detectors has always been difficult. In the past, this was only possible using expensive sources, which had been cross-calibrated against national standards. We describe a simple theoretical approach

1D kinetic modelling of the JET SOL with tungsten divertor plates. [PDF]

J Nucl Mater, 2013
In this work a fully kinetic model of the JET SOL with tungsten divertor plates has been developed. It includes the dynamics of main-ions (D+) and electrons, the neutrals (D, C, W) and the impurity particles (C+m, W+n). Our simulations show extremely low

Molecular deuterium behaviour in tungsten divertor on JET

Journal of Nuclear Materials, 2013
Abstract Molecular spectroscopy was used to observe molecular deuterium at the outer strike point of the new bulk tungsten JET divertor. The rotational and vibrational populations of the deuterium molecules in the ground state were determined from the deuterium Q-branches of Fulcher-α band emission ( d 3 Π u - → a 3 Σ

Initial growth phase of W-fuzz formation in ultra-long pulse helium discharge in LHD

Nuclear Materials and Energy, 2017
In order to confirm the formation of a tungsten fiberform nanostructure (W-fuzz) by helium plasma exposure in the large-sized plasma confinement device, the bulk tungsten with the size of 80 × 20 × 1.5 mm3 was inserted into the divertor leg position in ...

Determination of tungsten sources in the JET-ILW divertor by spectroscopic imaging in the presence of a strong plasma continuum

Nuclear Materials and Energy, 2019
The identification of the sources of atomic tungsten and the measurement of their radiation distribution in front of all plasma-facing components has been performed in JET with the help of two digital cameras with the same two-dimensional view, equipped ...
