Development of a Compact Divertor Plasma Simulator for Plasma-Wall Interaction Studies on Neutron-Irradiated Materials [PDF]

, 2017
0000-0001-7826-0046We have developed a compact divertor plasma simulator (CDPS) that can produce steady-state deuterium and/or helium plasmas with densities above ∼ 1018 m−3 for Plasma-Wall Interaction (PWI) studies of neutron-irradiated materials.

Comparison of ion cyclotron wall conditioning discharges in hydrogen and helium in JET

Nuclear Materials and Energy, 2023
This paper explores the plasma parameters of helium and hydrogen Ion Cyclotron Wall Conditioning (ICWC) discharges performed in JET as part of a He/H fuelling changeover experiment. The conducted study shows that plasma with a higher density is formed in

Charging of micro-particles in plasma-dust interaction [PDF]

, 2004
A microphysical description of the charging of dust grains in a plasma is presented. The model which is based on plasma-wall interaction processes predicts the dependence of the grain charge on the particle radius and on the particle temperature better ...

Global 3D full-scale turbulence simulations of TCV-X21 experiments with SOLEDGE3X

Nuclear Materials and Energy
First principle modelling of edge plasma turbulence including neutrals and plasma recycling on the wall remains a challenge, in particular due to the long time scales necessary to simulate to reach particle balance.

Pre-design of magnum-PSI: A new plasma-wall interaction experiment [PDF]

, 2007
The FOM-Institute for Plasma Physics Rijnhuizen is preparing the construction of Magnum-PSI, a magnetized (3 T), steady state, large area (80 cm(2)) high-flux (up to 10(24) H+ ions m(-2) s(-1)) plasma generator. The aim of the linear plasma device Magnum-
