First divertor exposure experiments of a renewable boron pebble aggregate in DIII-D
Erick Martinez-Loran, Angelica Ottaviano, Santhosh T. A. Kumar +21
Boron pebble aggregate was tested for the first time as a high-heat-flux granular plasma-facing material in a tokamak divertor. Exposures of up to $q_{\parallel} = \SI{80}{\MW\per\…

Deuterium retention in pre-lithiated samples and Li-D co-deposits in the DIII-D tokamak
M. Morbey, F. Effenberg, S. Abe +10
Divertor designs involving liquid lithium have been proposed as an alternative to solid designs and wall conditioning techniques. However, Li affinity with tritium poses a risk for…
