Plasma – Wall Interactions


  • Physics of Plasmas interacting with a wall: sheath and pre-sheath, limiter and divertor configurations.
  • Plasma states (density regimes): attached vs. detached plasma, density limit, radiating plasma, rotation.
  • Removing the heat: power balance (stationary, transient, location of deposits, radiation, technical components at high fluxes.
  • Control of particle recycling, fuel flow, exchange with the wall; plasma-wall interaction: sputtering and materials, generation and screening of impurities, pumping helium, cryo-pumps.
