European experts in Plasma-Wall Interaction and Exhaust met in IPP Prague in the frame of the EUROfusion WP PWIE meeting (24-27 March 2025) to discuss recent progress related to particle & heat loads, erosion and material migration, T retention, plasma characterization & laser-based diagnostics, and wall conditioning in fusion devices.
Part of the meeting was devoted to progress in code development and bench-marking simulations
with scrape-off layer and plasma-surface interaction modeling. Last but not least, recent analyses
of diverse tungsten and beryllium components of tokamak JET after its last experimental campaign
were presented.
WP PWIE is one of the 4 pillars of the Plasma Science department of EUROfusion with the main
objective to cover high priority activities for ITER and to support DEMO, and more generally
tokamaks / stellarators exploitation. This is achieved by the qualification and lifetime
optimization of plasma-facing components, PWIE code development/simulations and benchmark
experiments, completion of JET components analysis, and in-operando diagnostics optimisation for
material composition and retention.
