Divertor heat and particle control experiments on the DIII-D tokamakFunded under: EAEC-FUSION 12C
In this paper is presented a summary of recent DIII-D divertor physics activity and plans for future divertor upgrades. During the past year, DIII-D experimental effort focused on areas of active heat and particle control and divertor target erosion studies. Using the DIII-D advanced divertor system, control of the plasma density has been demonstrated. Divertor heat flux control by means of D(2) gas puffing and impurity injection were studied separately and in both cases up to a factor of five reduction of the divertor peak heat flux was observed. Using the DiMES sample transfer system, erosion data have been obtained on various material samples in well diagnosed plasmas. The results are compared with predictions of numerical models.
