Introduction of Laboratory
We are addressing the interactions between plasma and materials from the viewpoint of the magnetic confinement fusion. The plasma-material interactions are essential processes for realizing fusion plasma on the earth. For example, a solid hydrogen injection is employed to fuel hydrogen isotope into high-temperature fusion plasmas. Plasma and solid hydrogen interactions are studied for understanding the fueling processes which consist of the solid hydrogen ablation and plasmoid homogenization. Furthermore, in the plasma facing materials, plasma materials interactions are caused by the incident particles from the fusion plasma. To understand the elemental process of the interactions, material analyses using various method including a transmission electron microscope are carried out.
