Fusion energy research relies heavily on plasma modelling to predict the behaviour of the plasma and to interpret spectroscopic and other diagnostics of the plasma during operation. Plasma-wall interaction and the associated sputtering and desorption of wall material into the plasma are extremely important in determining the plasma composition, the erosion of surface material and changes in surface composition and material properties, and ultimately the feasibility of fusion power production. Modelling of plasma-wall interaction requires a combination of plasma and neutral gas transport codes and atomic, molecular, and plasma-material interaction data. Modelling of impurity behaviour in the core plasma and understanding core plasma diagnostics requires use of atomic cross section data and spectroscopic data. It is important for fusion scientists to learn about sources of these data, how they are created and how they are used.
The purpose of the Workshop is to train potential new researchers in fusion energy in the basics of plasma modelling with use of atomic, molecular and plasmamaterial interaction data. Lecturers will describe experimental and (mainly) computational methods by which such data are obtained, for example “collisional-radiative” modelling to obtain atomic data and molecular dynamics and Monte Carlo simulations to obtain data on plasma-material interaction, and they will describe how these data are used in modelling and diagnostics of fusion plasma experiments.
Topics will include plasma-material interaction data for pure and mixed materials, electron impact and radiative processes for atoms and ions, formation and dissociation of molecules and charge transfer processes. Prominent researchers in each area will guide the Workshop participants through these categories of data and their use in fusion plasma modelling. Specific widely used data collections will be described and exercises will be undertaken to apply these data to plasmas with parameters typical of current fusion devices.
