摘要：

Gas balance investigations were performed at the strongly pumped divertor tokamak ASDEX Upgrade. The gas inlet and pumping systems have been recalibrated, reaching an accuracy of about 3%, which is mostly given by uncertainties of the gas temperature. Clear saturation of the wall is observed after the wall is loaded with 19 X 10(21) at almost independent from details of the discharge program. For a saturated wall the retention of 1.5 +/- 3.2% is found. in former carbon wall experiments wall saturation is also found, but a higher D-retention is observed. (C) 2009 Elsevier B.V.
