Preparatory Consultancy Meeting for the Tungsten Ions CRP

The proposed Coordinated Research Project (CRP) on the Properties of Tungsten Ions in Fusion Plasmas will address data needs in the area of the ionization balance and spectroscopic and collisional properties of tungsten at temperatures between 1 keV and 10 keV, which are currently subject to large uncertainties and disagreements between theory and experiment.

This meeting, which was held in Room C0343 at IAEA Headquarters in Vienna from 29 – 30 August 2024, set out the scope of the CRP, identified potential participants, determined code comparison, benchmarking and evaluation activities, and established outcomes, performance indicators and a timeframe for the project.
