摘要

To find plasma facing materials (PFM), which must endure a plasma irradiation, is one of the important issues in order to realize the nuclear fusion reactor. Tungsten material is one of the candidates of PFMs. Bubble or nano-structure formation in tungsten is observed under the irradiation of helium onto the tungsten surfaces. We pick up the invasion process of helium into PFM and we developed the binary collision approximation (BCA) simulation. BCA simulation is performed by AC∨T (atomic collision in any structured target) code. Using this code, we calculate the penetration depth and sputtering yield which are basic information to reveal the nano-structure formation.
