From: Hydrogen and helium trapping in hcp beryllium

Fig. 5

a EDX scan of bubbles in beryllium with overlaid high-angular annular dark-field (HAADF). The elements Al, Mg and Si can be found at the bubble surface. The concentration profile of the major impurity, iron, is plotted for comparison. The purple arrow marks the extraction position for the concentration profiles shown in b68.
