description: This work is devoted to modeling the current flows in the Scrape-off layer of ASDEX Upgrade tokamak. An understanding of the physical processes in the Scrape-off layer is required for the precise determination of its parameters, in particular, the power decay length. In this paper, numerical simulation of four discharges of ASDEX Upgrade tokamak is performed by the two-dimensional SOLPS-ITER code. The simulation is based on the experimental data available. Good agreement with the experiment is obtained for all the studied discharges by the varying of the anomalous transport coefficients. Based on the simulation results, a thorough analysis of the current flows in the Scrape-Off layer was performed. As a result, the current structure in the edge plasma of a tokamak is presented and mechanisms of current closure are put for forward. The suggested structure is supported by the results of the simulations and the probe measurements for the ASDEX Upgrade tokamak.
