Spectroscopic investigation of ELM phenomena in the ASDEX-Upgrade divertor with high time resolution

  • 1. Max-Planck-Institut fuer Plasmaphysik, Garching (Germany)

Description

Improved tokamak H-mode confinement is associated with the formation of an insulating zone just within the separatrix. At a critical pressure gradient a sudden burst of MHD activity (an ELM) degrades edge confinement, releasing particles and energy into the scrape-off layer (SOL) which is subsequently transported to the divertor. Here, these phenomena are studied using spectroscopic diagnostics and target plate thermography of high spatial and temporal resolution. (author) 3 refs., 6 figs
