摘要: Carbon transport and migration were studied experimentally numerically in a high-density, low-confinement mode plasma the ASDEX Upgrade tokamak. On last day of operation 2004–2005 experimental campaign, 13CH4 was injected into vacuum vessel from low field side midplane. A poloidal set tiles subsequently removed analysed for 13C deposition. In this work measured deposition profile is interpreted using impurity code DIVIMP. The simulated distribution deviates significantly profile. simulations indicate that promptly deposited at wall vicinity injection port, transported to divertor plate predominately via scrape-off layer. B2-EIRENE solution produce stagnant flow main layer, contrast measurements other tokamaks. This likely cause discrepancy between calculated Key model parameters DIVIMP varied determine their effect on
