Comparison of recycling in the ASDEX divertor before and after hardening

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

Description

The original ASDEX divertor was not capable to dissipate the heat load of long pulse NBI and ICRH. In a partial reconstruction termed hardening, new water-cooled divertor components were installed. The modified divertor geometry resulted in some significant changes, e.g. in gas consumption and divertor pressure. Difficulties in obtaining a good H-mode are possibly connected to the modified recycling behaviour. However, a new regime with improved ohmic confinement (IOC) and reduced recycling is now found.
