Keywords:Beryllium, Microstructure, Gas retention characteristics

In-situ simultaneous measurements of gas retention property and microstructure evolution has been performed for beryllium irradiated with deuterium and helium ions.
Under irradiation and/or annealing was built to evaluate the dynamic gas release behavior in beryllium by directly association with microstructural changes.
