Component development for operation in a large-scale fusion device requires thorough
testing and qualification for the intended operational conditions. In particular environments …

Mirrors will be used as first plasma-viewing elements in optical and laser-based diagnostics
in ITER. Deterioration of the mirror performance due to eg sputtering of the mirror surface by …

Molybdenum is used as plasma-facing material in tokamaks and as material for plasma
optical diagnostics mirrors. Harsh conditions of neutron irradiation, exposure to hydrogen …

Metallic first mirrors (FMs) are foreseen to play a crucial role for all optical diagnostics in
ITER. It is highly important for the FMs to maintain a good reflectivity both in erosion and …

Our studies were aimed to determine the damage threshold of molybdenum (Mo) and
stainless steel (SS) mirrors to provide the maximum fluence which the mirror surfaces could …

A set of stainless steel (SS) and molybdenum mirror samples located in the divertor and at
the outer mid-plane of the vessel were exposed in JET from 2005 to 2007. A selection of …

This paper presents a laboratory-scale experimental investigation about the laser cleaning
of diagnostic first mirrors from tokamak-like contaminants, made of oxidized tungsten …

A series of tests have been performed to validate the resistance of the Silicon Carbide (SiC)
mirror as the first mirror material of ITER VUV spectrometers to all ITER environmental …

Divertor and midplane material evaluation systems (DiMES and MiMES) in the DIII-D
tokamak are used to address a variety of plasma–material interaction (PMI) issues relevant …

The use of an injected neutral beam—either a dedicated diagnostic beam or the main
heating beams—to localize and enhance plasma spectroscopic measurements can be …
