    Abstract

    Carbon migration has been investigated both experimentally and numerically by injecting isotopically marked methane (13CH4) at trace levels into a series of identical low-density, low-confinement mode discharges at the last day of the 2007 ASDEX Upgrade experimental campaign. The experiment is simulated with the DIVIMP code to test which assumptions are needed to reproduce the observed deposition pattern. Including a realistic poloidal flow profile was observed to be crucial in replicating the experimental results.
