Needs for cross-sections in fusion plasma researchFunded under: FP2-FUSION 10C
In describing the collision cross-section data needs for the present and future fusion programme, attention has been drawn to some of the actual practical difficulties of bringing the manifestly huge volume of available data into effective use in large fusion establishments. The disparate requirements of many applications from spectroscopic diagnostics through to purely theoretical plasma simulations must be balanced and consistent sources and qualities maintained. For these reasons, emphasis has been placed on management of data and on a modelling approach, generalised collisional radiative theory, which can ensure this. Needs in the three primary areas are examined: (i) confined high temperature plasma; (ii) neutral beams and beam penetrated plasma; (iii) edge, scrape-off-layer and divertor plasma; are examined. It is in these areas, particularly in beam penetrated plasma and divertor plasma, that strong continued development is anticipated over the next few years, and for which new refined cross-section data are essential. This report seeks to identify the reactants, classes of cross-sections, resolutions and broad precisions which are required to determine how they fit into the overall modelling picture.
