Formation of hot spots and arc ignition on tungsten with nano-tendril bundles under high-density hydrogen plasma exposure

Abstract Nano-tendril bundles (NTBs) are clusters of fuzzy nanostructures that form on tungsten surfaces when they are exposed to helium plasmas under specific conditions, reaching lengths of over 100 µm. Tungsten samples with NTBs and fuzz were exposed to high-density hydrogen plasmas in the Upgrad...
