Low deuterium retention in chemical vapor deposited tungsten with columnar grain structures under combined effects of displacement damage and helium seeding

Ting Wang, Arkadi Kreter, Peng Bi, Hanqing Wang et autres

Abstract Controlling hydrogen isotope retention is a critical challenge for plasma-facing materials (PFMs) in fusion reactors. Chemical vapor deposited tungsten (CVD-W), featuring columnar grain structures, has attracted increasing attention as a candidate PFM. However, its surface blistering and deuterium (D) retention behavior …
