Tungsten and Hydrogen in Edge Plasmas

Working Group 1

Atomic and Molecular Data Recommendation and Validation with CR Models


Missing tungsten data in edge plasma models

  • Rates for ionization, recombination and excitation
  • Multi-step ionization and excitation
  • Non-resonant charge exchange

Recommended tungsten and hydrogen data for edge plasma modelling

  • Large scatter in the various sets for W atomic data (in particular excitation rates)
  • Hydrogen molecular data: impact and need of vibrationally-, rotationally- and isotopically-resolved data; mixed molecules; limited data available for T, TH and TD
  • Metastable states of W
  • Uncertainties of W and hydrogen data: atomic data used in CRM dependent on the range of plasma parameters
