In order to investigate fundamental processes of plasma-wall interactions of tokamak devices, specimens for Transmission Electron Microscope (TEM) observation were exposed to plasma of High-Field Tokamak TRIAM-1. TEM or SEM observation showed an initial process of droplet ejection from molten surfaces and low energy hydrogen-induced microstructures. Mechanisms of the damage processes observed and their implication to wall/limiter performance were discussed.
