Summary:
Tungsten nano structure, e.g. a bubble or a fuzz structure, has been studied recently by a lot of plasma-wall interaction researchers. The purpose of these researches is to avoid the decrease of the mechanical property and the heat conductivity of the original tungsten material. To achieve this purpose, we estimate the sputtering yield, the absorptivity and the mean depth of helium gas for the tungsten using BCA simulation code AC$ﾂforall$T (atomic collision in any structured target) We obtain the sputtering yield, the absorptivity and the mean depth of helium gases for the tungsten with crystal surfaces. We also found that these physical quantities depend on the crystal orientation of the target tungsten.
