Objectives

To increase the capability of Member States to undertake fusion plasma and fusion materials modelling by supporting the development of novel techniques in fusion reactor design through the enhancement of the global knowledgebase of atomic and molecular data for vapour shielding modelling, with a particular focus on liquid metals.

Specific objectives

Assemble, evaluate and recommend atomic and molecular data needed for the modelling of vapour shielding, particularly cross sections for ionization, recombination, charge exchange (CX), rovibrational excitation (for molecules) and momentum transfer. Also of concern are data for radiative processes inside vapours, including line shapes, emission and absorption coefficients, radiative cooling rates, stopping power, and other radiative properties of warm dense matter. Comparison of theory with experiment should be achieved wherever possible.

Assess the impact of impurities such as O, C and N in their interactions with liquid metal species, particularly Li.

Assemble, evaluate and recommend relevant data on metal hydrides for vapour shielding models, particularly those involving Li and Sn.

Investigate the effect of surface chemistry, especially hydrogen co-deposition, on sputtering and evaporation of plasma-facing materials.
