The topics for the 8th International Workshop on Plasma Material Interaction Facilities for Fusion Research are:
- Development of plasma-material interaction facilities
- Testing of first wall and divertor materials
- Plasma edge and divertor physics
- Diagnostics for plasma and material surface
- Theory and modelling
Development of plasma-material interaction facilities
This work groups the technological issues across PWI devices. These include:
- developing plasma sources;
- understanding plasma heating;
- handling the heat-capturing components (including neutron-irradiated materials);
- operating high density plasmas with high ion particles and heat; and
- operating dedicated facilities with high heat fluctuations.
Testing of first wall and divertor materials
Conventional and advanced materials (including liquids) are to be tested for their use as plasma-facing materials in a reactor. The evaluation criteria include erosion, fuel retention, evolution of surface morphology and structural damage (cracking, melting).
Plasma edge and divertor physics
This activity includes characterizing the edge of the plasma and related processes such as plasma recombination. Developing methods to optimize ion particle and heat loads in plasma-facing components (including impurities and detachment) will also be examined.
Diagnostics for plasma and material surface
A strong focus of the PWI TCP is to develop advanced surface and plasma diagnostics. Sophisticated diagnostics are the key to a better understanding of physics mechanisms in the chamber.
Theory and modelling
The modelling activities are an integral part of the PWI TCP work program and knowledge gained is transferred tokamak and stellarator devices. Modelling activities include:
- atomic processes in the plasma at the heat extractor
- plasma in linear devices;
- surface modifications under plasma impact;
- hydrogen movement in plasma-loaded materials; and
- material damage under plasma and heat loads.
