Edge Localized Mode (ELM). 4. Recent progress of ELM plasma transport study in SOL and divertor

Selection of plasma facing components and ELM plasma transport phenomena at plasma detachment are described. Transportation of heat and particle flux to divertor at ELM, heat load of divertor and selection of the plasma facing components, irradiation time and heat load of divertor, plasma flow of divertor by ELM, transport of ELM plasma at plasma detachment, dynamics of ELM plasma runs across the magnetic field, plasma transport rate to the outside and heat and particle load of the first wall are stated. The life of divertor tile with tungsten and CFC (carbon fiber composite), change of the highest temperature and heat flux density of outside of divertor at ELM, change of magnetic coil fluctuation, ion saturation current density, Dα signal, heat flux density at ELM in JT-60U, the energy loss by ELM to heat load of divertor in JET, heat load pattern of outside of divertor in ASDEX-Upgrade, image of high-speed visible television camera at ELM in MAST, the peak value of ion saturation current density at JT-60U, and ELM plasma velocity in ASDEX-Upgrade are described.
