Glow Discharge Boronization and Real-Time Boronization Using an Impurity Powder Dropper in LHD
Nuclear Materials and EnergyIn the Large Helical Device (LHD), boronization is utilized for wall conditioning, employing two distinct methods: glow discharge using diborane gas and the injection of boron powder into the plasma via an impurity powder dropper (IPD).

Global modeling of wall material migration following boronization in NSTX-U
Nuclear Materials and Energy, 2019 Boronization is commonly utilized in tokamaks to suppress intrinsic impurities, most notably oxygen from residual water vapor. However, this is a temporary solution, as oxygen levels typically return to pre-boronization levels following repeated plasma ...

Hydrogenic retention with high-Z plasma facing surfaces in Alcator C-Mod [PDF]
, 2009 The retention of deuterium (D) fuel in the Alcator C-Mod tokamak is studied using a new 'static' gas balance method. C-Mod solely employs high-Z molybdenum (Mo) and tungsten (W) for its plasma facing materials, with intermittent application of ...
