The behavior of bubbles and blisters in aluminum during 10 keV He + ion irradiation at 573 K was investigated. Processes of the evolution of surface damage were clarified using an in-situ electron microscope observation system. The difference among irradiation effects obtained by three kinds of experiments at room temperature was examined using both 15 keV H +2 and 12 keV He+ ions. The obtained results were interpreted by difference in the production rate of vacancies introduced by gas implantation and different mobility of these two ions in aluminum.
