Tungsten and Hydrogen in Edge Plasmas

Working Group 2

Plasma Experiments and Comparison Activities with Collisional-Radiative Models


Working Group 2a: Tungsten and Hydrogen Experiments with Fusion Devices and Linear Plasma Devices

Chair: Sebastiján Brezinsek

  • Tungsten ground state population experiments
  • Joint experiments and simulations on Tungsten influx determination in edge plasma region: UTA regions, W V – W IX line utilization, forbidden transitions in the visible range
  • Hydrogenic molecules in the detachment process
  • Hydrogen recycling with ro-vibrationally and isotopically resolved data including mixed hydrogen molecules
  • Benchmarking experiments with linear devices and high flux plasma devices

Working Group 2b: The inclusion of reduced photon opacity information in collisional-radiative models:

Chair: Sven Wiesen

  • 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
