Abstract

Radial transport of poloidal momentum in the scrape-off layer (SOL) of ASDEX Upgrade was investigated. A reciprocating probe was used with a probe head containing six Langmuir probes with which the poloidal and radial electric field components and the density were determined. Separating all quantities into stationary and fluctuating parts, four components of the momentum transport were evaluated separately. We see a distinct change in behaviour between L- and H-mode discharges. Particularly the direction of momentum flux at the probe location is opposite between L- and H-mode.
