Description
The Fokker-Planck code CQL3D has been used to investigate the effect of radial particle diffusion on ECCD current density profiles in the TCV tokamak. For two discharges with electron internal transport barriers (eITB), the jcd and the resulting q-profile have been calculated and reconstructed. The studied eITBs are of two kinds: fully sustained non-inductive eITB with off-axis co-current ECCD, or with a large Ohmic current and on-axis counter ECCD. It is shown that different diffusion profiles do modify the ECCD current density profiles, but that the resulting q-profiles are less influenced due to the resulting necessary self-consistent inductive current contribution
