2nd Meeting of the Global Network for the Atomic and Molecular Physics of Plasmas

The second meeting of the IAEA Global Network for the Atomic and Molecular Physics of Plasmas will be held online from 6 – 9 December 2021. The Scientific Secretary is Christian Hill (Unit Head, Atomic and Molecular Data Unit).

This meeting will focus on aspects of the collisional-radiative properties of tungsten and hydrogen in the edge plasma of fusion devices, following on from a Technical Meeting on this topic held in March 2021.

If you wish to participate in this meeting, please register and, optionally, submit an abstract for a presentation on the IAEA Conferences meeting page.

Topics

  • 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
  • The inclusion of reduced photon opacity information in collisional-radiative models
    • Revised CRM with (semi)opaque lines
    • Full non-linear model or a reduced CRM
    • Isotope effects of collisional broadening in high plasma density
    • Wall reflection models for photons: on W and Be or deposited layers; surface roughness effects
  • Data needs for ITER
    • Accuracy improvement for ionization, recombination, radiation and CX rates of W
    • CR: to obtain reliable charge distribution of W for modelling W upstream migration and penetration to core plasma
    • Spectral lines of interest W0 to at least W64+
    • Dielectronic recombination rates and photon opacity for W vapour shielding during fast transients
