TL;DR: In this paper, the PISCES-A nanostructures were exposed in the lower divertor of DIII-D using the divertor material evaluation system and two samples were exposed to deuterium H-mode plasmas.

TL;DR: In this article, the surface analysis showed the formation of 1.5 nm diameter He bubbles in the surface of W buttons after only a single DIII-D discharge, similar to the bubble layer resulting from the 2000 s exposure in PISCES-A.

TL;DR: In this paper, a mixed-material DIVIMP-WallDYN model is presented that simultaneously reproduces tungsten (W) erosion and deposition patterns observed during the DIII-D Metal Rings Campaign, in which a toroidally symmetric set of W-coated tiles were installed in the carbon (C) D III-D divertor.

TL;DR: In 2010, two thermo-oxidation experiments (?O-bakes?) were performed in the DIII-D tokamak Internal surfaces of the tokak, as well as a number of specimens inserted into the torus, were exposed to a mixture of 20% O2/80% He at a nominal pressure of 95?Torr (127?kPa) at a temperature of 350?360??C for a duration of 2?h.
