10 Past, Present and Future CRPs : Tritium Inventory in Fusion Reactors : Atomic and Molecular Data for Plasma Modelling : Atomic Data for Heavy Element Impurities in Fusion Reactors : Data for Surface Composition Dynamics Relevant to Erosion Processes : Characterization of Size, Composition and Origins of Dust in Fusion Devices : Light Element Atom, Molecule and Radical Behaviour in the Divertor and Edge Plasma Regions : Spectroscopic and Collisional Data for W from 1 ev to 20 kev : Data for kinetic modelling of molecules of H and He and their isotopes in fusion plasma : Erosion and Tritium Retention for Beryllium PlasmaFacing Materials (tentative) PlasmaWall Interaction of Tungsten and its Alloys in Fusion Devices (More tentative) Data for kinetic modelling of hydrocarbon ions in fusion plasma

11 CRP on Spectroscopic and Collisional Properties of Tungsten from 1 ev to 20 kev Objectives Concerned with W in all plasma regions, edge to core Theory and experiment are both represented, with overlap among and between the two Aim to produce validated database for tungsten in plasma Data needs Electronimpact, radiative and photoninduced, and heavy particle collision processes Crosssections for kinetic modelling Rate coefficients for macroscopic modelling Spectroscopic signatures for diagnostics Research Coordination Meetings First RCM: 1315 December 2010 Participants A.

26 Requirement for Plasma Modelling: Reliable data sets for AMNS data Data needs to be verified by an expert Data needs to be robust Data needs to be comprehensive Data needs to be easy to use Version control: know what data was used for a particular run, and which runs used a particular version of the data Needs to be efficient Needs to be able to address special needs Require a Recommended & Internationally Agreed Library for Atomic, Molecular, Nuclear, Surface Data
