    Abstract

    Dissipation of the exhaust power in the tokamak scrape-off layer (SOL) is one of the key challenges for divertor operation in ITER and DEMO. Of particular concern is the mitigation of strongly peaked or asymmetrically distributed power loads on the low- and high-field-side target plates. In this contribution, we discuss the role of cross-field drifts in modifying the divertor power load distribution in the ASDEX Upgrade tokamak. A medium-density L-mode discharge exhibiting a typical, high level of asymmetry in normal field configuration (ion ∇B drift towards the lower divertor) is chosen for a detailed analysis.
