概要	Deuterium (D) retention in tungsten (W) subjected to pulsed D plasma bombardment (surface absorbed energy density Q similar to 0.5-0.7 MJ m(-2) at similar to 0.3-0.5 ms) has been investigated in a magnetized coaxial plasma gun. A high temperature desorption peak of D(2) appears at similar to 1000-1100 K following transients at similar to 0.5 MJ m(-2). At a higher Q similar to 0.7 MJ m(-2), the total amount of D retained in W is significantly reduced. Nano-sized helium (He) bubbles, created by steady-state He plasma pre-exposure at similar to 573 K, slightly lower D retention, while a significant reduction is observed for a W fuzzy surface formed by steady-state high temperature (similar to 1100 K) He plasma pre-exposure.
