Modelling of plasma-edge and plasma–wall interaction physics at JET with the metallic first-wall [PDF]
Physica Scripta, 2016 An overview is given on the recent progress on edge modelling activities for the JET ITER-like wall using the computational tools like the SOLPS or EDGE2D-EIRENE code. The validation process of these codes on JET with its metallic plasma-facing components is an important step towards predictive studies for ITER and DEMO in relevant divertor operational

Plasma-Wall Interaction in Magnetically Confined Fusions Plasmas [PDF]
Fusion Science and Technology, 2008 The control of wall loads in fusion devices, in particular with respect to the life time limitations of wall components due to material erosion and migration, will be decisive for the realisation o...

Fusion Science and Technology, 2006 The control of wall loads in fusion devices, in particular with respect to the life time limitations of wall components due to material erosion and migration, will be decisive for the realisation of a fusion power plant operating in steady state. In ITER the primary goal for plasma-wall interaction is the achievement of a high availability of this ...

X-ray spectroscopic study of charge exchange phenomena in plasma-wall interaction [PDF]
EPJ Web of Conferences, 2013 Jets of energetic ions launched at laser-burnt-through foils represent an efficient tool for investigation of plasma interaction with solid surfaces (plasma-wall interaction, PWI) and for description of transient phenomena occurring close to the walls ...

Effect of anisotropic non-Maxwellian electron distribution function on plasma-wall interaction in Hall thrusters [PDF]
, 2012 Due to the extreme plasma conditions in Hall thrusters, such as electron temperature anisotropy and non-Maxwellian electron distribution function (EDF), understanding the plasma-wall interaction is a very challenging task.

Studies of the non-axisymmetric plasma boundary displacement in JET in presence of externally applied magnetic field [PDF]
, 2015 Non-axisymmetric plasma boundary displacement is caused by the application of the external magnetic field with low toroidal mode number. Such displacement affects edge stability, power load on the first wall and could affect efficiency of the ICRH ...

Impact of plasma-wall interaction and exhaust on the EU-DEMO design
Nuclear Materials and Energy, 2021 In the present work, the role of plasma facing components protection in driving the EU-DEMO design will be reviewed, focusing on steady-state and, especially, on transients. This work encompasses both the first wall (FW) as well as the divertor. In fact,

Arc behaviour on different materials in ASDEX Upgrade
Nuclear Materials and Energy, 2021 Arcs, a source of dust particles and a localized erosion mechanism of the plasma-facing components, are found in all major fusion plasma devices. Measurements of arcs require diagnostics with high temporal and local resolution, which are not available at
